Climbing Lhotse: The Fourth-Highest Mountain & Everest’s Technical Twin
At 8,516 meters (27,940 ft), Lhotse is the world’s fourth-highest mountain — and one of the most interesting 8,000m objectives in the Himalaya. Sharing Everest’s Base Camp, the Khumbu Icefall, the Western Cwm, and much of the Lhotse Face up to approximately 7,400m, Lhotse is inseparable from its famous neighbor until the routes diverge at the Yellow Band. The name itself — from Tibetan meaning “South Peak” — reflects this close geographic bond. This complete guide covers the Reiss Couloir standard route and the legendary South Face, the 2026 Nepal permit structure following the September 2025 fee increase to $3,000, the 1956 Swiss first ascent by Ernst Reiss and Fritz Luchsinger, Krzysztof Wielicki’s solo winter ascent on December 31, 1988, the rare Everest-Lhotse Double Crown, expedition costs of $40,000-$100,000+, and a complete recap of the 2025 season.

Elev: 5,364 mLhotse has an identity problem — it lives permanently in Everest’s shadow despite being the world’s fourth-highest mountain at 8,516 meters, and climbers often underestimate it precisely because it shares so much infrastructure with its more famous neighbor. But experienced climbers know better: Lhotse is technically more serious than Everest above the Yellow Band. Both mountains follow the identical route from Base Camp through the Khumbu Icefall and up the Lhotse Face to approximately 7,400m, where the paths diverge — Everest climbers traverse left toward the Geneva Spur and South Col, while Lhotse climbers continue right into the steeper upper Lhotse Face and the narrow Reiss Couloir leading directly to Lhotse’s summit. The couloir is named for Ernst Reiss, who with Fritz Luchsinger completed the first ascent at 2:50 PM on May 18, 1956, as part of the Swiss Everest-Lhotse Expedition that also made the second and third ascents of Everest six days later. Polish climber Krzysztof Wielicki completed the first winter ascent solo on December 31, 1988 — one of the most celebrated achievements in winter Himalayan mountaineering. The 2025 season produced strong Lhotse summits including multiple teams on May 15 and the rare Everest-Lhotse Double Crown attempt by Jocelyn Cayer and Ashish. This complete guide covers the Reiss Couloir standard route, the legendary South Face, the 2026 Nepal permit structure following the September 2025 increase to $3,000, expedition costs of $40,000-$100,000+, and the 2025 season’s hard-earned lessons.
Key Lhotse Facts: Elevation, Ranking & Route Overview
Before diving into routes, logistics, and the 2026 permit structure, here are the essential facts every Lhotse climber should know about Everest’s fourth-highest neighbor.
Why Lhotse Is More Serious Than Its Reputation Suggests
Lhotse is often mistakenly treated as “Everest with less commitment” — a cheaper, shorter, easier version of its famous neighbor. This is dangerously wrong. While Lhotse shares infrastructure with Everest for the lower two-thirds of the route, the upper mountain is technically more demanding than Everest’s South Col route, and the climb demands genuine 8,000m capability throughout. Here are the eight reasons experienced climbers treat Lhotse with the respect it deserves.
The Upper Lhotse Face Is Steeper Than Everest
Above the Yellow Band at approximately 7,400m, the Lhotse and Everest routes diverge — and Lhotse’s gets harder. While Everest climbers traverse left to the relatively moderate Geneva Spur and South Col, Lhotse climbers continue right up the steeper upper Lhotse Face into the Reiss Couloir. This upper section involves sustained 50-60 degree ice climbing with confined passages, exposed traverses, and cumulative vertical gain that demands technical competence at extreme altitude. Climbers who struggled with the lower Lhotse Face will find the upper section significantly harder.
The Khumbu Icefall Is Lhotse’s Too
Every Lhotse climber must navigate the Khumbu Icefall — the chaotic maze of seracs, crevasses, and ladder crossings between Base Camp and Camp 1. The Icefall is one of the most dangerous features in all commercial climbing, responsible for multiple deaths each decade including the 2014 avalanche that killed 16 Nepali workers. Lhotse climbers cross the Icefall multiple times during acclimatization rotations and the summit push — each passage carrying equivalent risk to an Everest climb through the same terrain. This is not reduced risk because the summit is different.
The Reiss Couloir Variability
The Reiss Couloir can vary dramatically in character from season to season. Some years present mostly ice climbing with clean fixed-line work possible. Other years feature significant mixed rock-and-ice climbing that dramatically increases difficulty. Couloir conditions are one of the key assessments operators make each season — when conditions are deemed too dangerous, otherwise-capable expeditions have been forced to turn back within meters of success. The couloir’s narrow width also creates bottleneck scenarios when multiple teams attempt summit on the same day.
Crowding With Everest Traffic
Because Lhotse shares infrastructure with Everest through the Yellow Band, Lhotse climbers share crowded fixed lines with the much larger Everest population. Nepal typically issues 450-500+ Everest permits in spring plus another 50-100 Lhotse permits, creating significant traffic on the Lhotse Face. Bottlenecks form at key transitions. Queuing occurs at fixed-line anchors. The 2024-2026 Nepal regulations requiring 1 guide per 2 climbers on 8,000m peaks have increased overall population further. Lhotse climbers cannot escape Everest’s crowds — they are inseparable companions.
Summit Day Above 8,000m
Lhotse summit day places climbers in the extreme death zone for 8-12 hours — less than Everest’s 10-14 hours but still significant cumulative exposure. Climbers depart Camp 4 (typically at 7,900-8,000m on the upper Lhotse Face), ascend through the Reiss Couloir to the summit at 8,516m, and descend back to Camp 4 all in a single effort. Oxygen management, hydration, and pacing decisions made lower on the mountain directly affect summit-day success. The altitude is less extreme than Everest but still demands strict discipline.
Serac and Rockfall Exposure
The upper Lhotse Face has exposure to serac fall from hanging glaciers above and rockfall from the mixed rock-and-ice terrain around the Reiss Couloir. Unlike Everest’s summit ridge which is primarily snow and ice with relatively stable surroundings, Lhotse’s upper mountain includes geological features that can shed rocks or ice without warning. Climbers passing through the couloir are exposed to these hazards, and some seasons have seen rockfall incidents force changes to route timing or even route closure.
The South Face Is the Hardest in the Himalaya
Lhotse’s South Face is a 3,300m vertical wall on the opposite side of the mountain from the standard route — and it is widely considered one of the most technically difficult and dangerous climbs on any 8,000m peak. The face has been climbed only a handful of times. Polish legend Jerzy Kukuczka died on the South Face in 1989 while attempting a new route. The face is not a commercial objective and is reserved for elite alpinists, but its existence as part of Lhotse shapes the mountain’s broader reputation and reminds climbers that Lhotse is genuinely serious terrain, not a “beginner” 8,000m option.
Three Years Without Summits (2014-2016)
Lhotse was not successfully summited in 2014, 2015, or 2016 — three consecutive seasons without a single ascent. The 2014 season ended after the April avalanche in the Khumbu Icefall killed 16 Nepali workers, effectively closing the mountain. The 2015 season was cancelled after the April 25 Nepal earthquake triggered an avalanche that killed 22 people at Everest Base Camp. The 2016 season saw limited climbing activity with no Lhotse summits recorded. The mountain resumed regular summit traffic from 2017 onward. This three-year gap illustrates how even “standard” 8,000m peaks can be closed by regional events — and why climbers need flexibility in their planning timelines.
Who Can Realistically Climb Lhotse?
Lhotse is one of the more accessible 8,000m peaks for climbers with solid mountaineering foundations — but it is not a beginner mountain, and the shared infrastructure with Everest does not reduce the minimum experience requirements. Understanding the actual prerequisites helps aspiring Lhotse climbers assess whether the mountain is a realistic next step or still years of progression away.
Minimum Experience Prerequisites
Reputable Lhotse operators typically require clients to demonstrate the following prior experience before acceptance:
- Multiple successful 6,000-7,000m summits — ideally including Island Peak, Ama Dablam, Baruntse, Himlung Himal, or similar peaks that build altitude experience and technical skills
- Strong fixed-line and jumar competence — the Lhotse Face and Reiss Couloir both involve extensive fixed-line work at steep angles
- Khumbu Icefall-equivalent experience — if not the Icefall itself, comparable icefall and ladder-crossing experience on other peaks
- Comfortable movement on 40-55 degree ice — the Lhotse Face slope character is directly applicable; climbers should have crampon technique ready before arrival
- Cold-weather endurance below -30°C — summit-day temperatures routinely approach -35°C with wind chill
- Mature high-altitude decision-making — particularly important given the crowding with Everest traffic and the potential for queuing at bottlenecks
Lhotse Is Appropriate For:
Experienced climbers targeting their first 8,000m summit. Lhotse is one of the more common “first 8,000m peak” choices alongside Manaslu and Cho Oyu because of its moderate technical demands, established infrastructure, and slightly lower summit altitude than Everest. Climbers with strong 7,000m experience can reasonably attempt Lhotse as their first 8,000m peak if they have appropriate technical skills.
Climbers preparing for Everest. Lhotse is widely recommended as Everest preparation because it uses the same infrastructure — the Khumbu Icefall, Western Cwm, Camps 1-2-3, and the Lhotse Face are all shared. A climber who completes Lhotse has genuinely practiced the skills needed for Everest, unlike more divergent preparation peaks.
Climbers pursuing all 14 eight-thousanders. Lhotse is one of the peaks that 14-8000ers project climbers often complete as part of an extended spring season in the Everest region, sometimes combined with Everest itself.
Climbers attempting the Everest-Lhotse Double. For climbers with exceptional fitness and two 8,000m summits of experience, the Everest-Lhotse Double — summiting both peaks in a single spring season — is one of the most respected achievements in modern commercial climbing.
Lhotse Is Not Appropriate For:
Climbers without any 6,000m+ experience. Despite the shared infrastructure with Everest, Lhotse remains an 8,000m peak with genuine technical demands. Climbers jumping from Colorado 14ers or alpine peaks directly to Lhotse are at elevated risk.
Climbers who view Lhotse as “Everest-lite.” The technical terrain above the Yellow Band is harder than anything on Everest’s South Col route. Climbers who approach Lhotse casually because they think it’s “easier than Everest” often find themselves overwhelmed by the upper mountain.
Climbers uncomfortable with Icefall exposure. Multiple Khumbu Icefall crossings during rotations and summit push expose climbers to the single most dangerous feature in Himalayan climbing. Climbers who cannot manage the psychological weight of Icefall crossings will struggle.
Climbers without 8,000m-rated gear. Lhotse’s technical terrain and extreme altitude demand proper 8,000m gear — a down suit, 8,000m boots, supplemental oxygen system, and quality technical climbing equipment. Climbers arriving with gear better suited to 6,000m peaks will fail.
A realistic progression to Lhotse for an aspiring 8,000m climber typically spans 4-7 years of serious mountaineering: 1-2 years building technical skills on alpine peaks (Rainier, Denali, Aconcagua), 2-3 years on 6,000-7,000m peaks (Island Peak, Ama Dablam, Baruntse), and then Lhotse as a first or early 8,000m summit. Climbers targeting Everest within the next 1-2 years often choose Lhotse specifically as preparation because the route overlap is so extensive. The key principle: Lhotse is a legitimate 8,000m mountain that demands legitimate 8,000m preparation, even if it can look deceptively accessible from Base Camp.
Lhotse History: From 1955 Reconnaissance to the Double Crown Era
Lhotse’s climbing history is tightly interwoven with Everest’s. From the first reconnaissance in 1955 through the 1956 Swiss first ascent, Wielicki’s 1988 solo winter climb, the deadly South Face attempts, and the modern Double Crown era, Lhotse has always lived in relationship with its famous neighbor. Understanding this history provides context for the mountain’s character and its place in world mountaineering.
Early Reconnaissance (1955)
The first serious attempt on Lhotse came in 1955 as part of the International Himalayan Expedition, a multi-national effort that included Swiss climbers and additional European members. The expedition approached the Western Cwm and attempted the northwest face of Lhotse, reaching approximately 8,100 meters before being driven back by unexpectedly strong winds and extreme cold. The expedition did not summit but produced critical reconnaissance data — including the identification of the steep couloir cutting up the northwest face that would become the successful line in 1956. The 1955 expedition also completed the first detailed map of the Everest region (a 1:50,000 photogrammetric map) under the direction of Schneider, and documented Khumbu cultural topics through short films.
The 1956 Swiss First Ascent
The successful ascent came through the Swiss Mount Everest-Lhotse Expedition of 1956, led by Albert Eggler. The expedition was planned from the start as a dual-summit attempt — Lhotse first, then Everest. The team reached Base Camp on April 7, 1956, and spent weeks establishing camps through the Khumbu Icefall and Western Cwm.
On May 18, 1956 at 2:50 PM, Swiss climbers Ernst Reiss and Fritz Luchsinger reached the summit of Lhotse via the northwest face couloir that now bears Reiss’s name. From Camp VI, they fought through biting winds and extreme temperatures, climbing through the steep snow couloir and over a band of green rock to reach the summit ridge. The wind was so severe at the summit that the climbers could not stand upright — they drove their ice axes into the snow and held on while taking summit photos.
Six days later, on May 24, 1956, the same Swiss expedition made the second ascent of Mount Everest (Jürg Marmet and Ernst Schmied), with a third Everest ascent the following day by Hans-Rudolf von Gunten and Adolf Reist. The 1956 expedition thus became the first in history to summit both Everest and Lhotse in a single season — a precedent that would inspire the modern Double Crown tradition.
Lhotse Shar and the Subsidiary Summits
Lhotse is not one mountain but a complex of four distinct summits:
- Lhotse Main (8,516m) — the highest point, first climbed 1956
- Lhotse Middle (8,414m) — remained the highest unclimbed named point on Earth until May 23, 2001, when a Russian team (Eugeny Vinogradsky, Sergei Timofeev, Alexei Bolotov, Petr Kuznetsov) completed the first ascent
- Lhotse Central II (8,372m) — a secondary subsidiary peak
- Lhotse Shar (8,383m) — first climbed May 12, 1970 by Austrians Sepp Mayerl and Rolf Walter via the southeast ridge
Each of these summits counts as a distinct climbing objective with its own history. Lhotse Middle’s late first ascent (2001) made it the last of the subsidiary 8,000m summits to fall — a reminder of how much objective climbing history remained even into the modern era.
The 1988 Winter Ascent
On December 31, 1988, Polish climber Krzysztof Wielicki completed the first winter ascent of Lhotse — climbing solo, one of the most celebrated achievements in winter Himalayan mountaineering. Wielicki’s winter ascent was part of the broader Polish winter program that dominated 1980s Himalayan climbing, with Polish teams completing first winter ascents of Everest, Kangchenjunga, Dhaulagiri, Cho Oyu, Manaslu, Annapurna, and Lhotse during the decade. Wielicki went on to complete all 14 eight-thousanders, joining Messner and Kukuczka in that elite club.
The South Face and Jerzy Kukuczka’s Death
Lhotse’s South Face — a 3,300m wall on the opposite side of the mountain from the standard route — has been the site of some of the most significant tragedies in Himalayan climbing. The face had defeated multiple expeditions by the late 1980s and remained a major unclimbed objective.
On October 24, 1989, Polish legend Jerzy Kukuczka — who had completed all 14 eight-thousanders the previous year, becoming the second person (after Messner) to do so — died on the Lhotse South Face during a new-route attempt. Kukuczka fell when a rope broke while leading a difficult pitch above 8,200m. His death was one of the most profound losses in 20th century mountaineering. The South Face has been climbed a handful of times since (including a contested claim by Tomo Cesen that was later retracted), but remains one of the most feared objectives in the world.
The 2014-2016 Lost Years
Lhotse saw no successful summits for three consecutive seasons — 2014, 2015, and 2016 — due to cascading Everest-region events:
- 2014: An April 18 avalanche in the Khumbu Icefall killed 16 Nepali workers, effectively ending the season. Most expeditions withdrew out of respect and safety concerns.
- 2015: The April 25 Nepal earthquake (magnitude 7.8) triggered an avalanche that killed 22 people at Everest Base Camp — one of the deadliest single incidents in Himalayan history. The entire season was cancelled.
- 2016: Although Everest saw limited summits, Lhotse did not record a single summit that year.
Regular Lhotse climbing resumed from 2017 onward and has continued with typical patterns ever since.
The Modern Double Crown Era
In recent years, the most prestigious Lhotse achievement has become the Everest-Lhotse Double Crown — summiting both peaks in rapid succession. The compressed version attempts both summits within 24 hours: summit Everest via the South Col, descend to the South Col, traverse to Camp 4 on the Lhotse side, and push to Lhotse’s summit. Mingma Dorchi Sherpa set a notable record in 2019, climbing both in just over 6 hours. The 2025 season saw a well-documented Double Crown attempt by Jocelyn Cayer and Ashish. The feat requires exceptional fitness, optimal weather windows, and the kind of preparation that modern commercial operations at the premium tier can support.
Lhotse’s Climbing Routes: Reiss Couloir & the South Face
Lhotse has two routes of significant mountaineering history: the West Face / Reiss Couloir standard route (used by 95%+ of all successful summits) and the legendary South Face (one of the hardest climbs in the world, attempted by only a handful of elite alpinists). Lhotse Shar and Lhotse Middle are separate summits with their own routes. This guide focuses on the standard route since it is the only realistic option for commercial climbing.
| Route | Country | Base Camp Elev | Key Features | Share | Character |
|---|---|---|---|---|---|
| West Face / Reiss Couloir | Nepal | 5,364 m (shared with Everest) | Khumbu Icefall, Western Cwm, Lhotse Face, Reiss Couloir | ~95%+ | Standard commercial |
| South Face | Nepal | ~5,200 m | 3,300m vertical wall, extremely technical | ~1-2% | Elite alpine |
| Lhotse Shar (8,383m) | Nepal | ~5,400 m | Southeast ridge, separate summit | Rare | Subsidiary peak |
| Lhotse Middle (8,414m) | Nepal | ~5,400 m | Technical traverse, first climbed 2001 | Extremely rare | Subsidiary peak |
West Face via the Reiss Couloir
The West Face route is the standard commercial route on Lhotse and the overwhelming choice for all guided expeditions. It begins from Everest Base Camp at approximately 5,364m — the same Base Camp used by Everest climbers — and follows the identical route through the Khumbu Icefall and Western Cwm up to approximately 7,400m on the Lhotse Face. The route was pioneered by the 1956 Swiss first-ascent expedition and has been the standard line ever since.
The route’s character evolves through distinct zones. The Khumbu Icefall between Base Camp and Camp 1 at 5,943m is a chaotic maze of seracs, crevasses, and ladder crossings maintained by the “Icefall Doctors” (SPCC) each season. The Western Cwm between Camp 1 and Camp 2 at 6,400m is a broad glacial valley — the “Valley of Silence” — with crevasses and hot temperatures in direct sun. The Lhotse Face rising above Camp 2 is a 1,125m wall of glacial blue ice at 40-55 degrees with occasional 80-degree bulges, requiring fixed-line work with jumars. Camp 3 is typically placed partway up the Lhotse Face around 7,200m. Above the Yellow Band at approximately 7,400m, the routes diverge — Everest climbers traverse left to the Geneva Spur while Lhotse climbers continue right up the steeper upper face.
Camp 4 for Lhotse is typically established at 7,900-8,000m on the upper Lhotse Face, not at the Everest South Col. Summit day involves ascending the final portion of the Lhotse Face, entering the Reiss Couloir at approximately 7,600m, and climbing 900+ vertical meters through the narrow couloir to exit near the summit cone. The summit at 8,516m offers dramatic views of Everest immediately north. Total summit day from Camp 4 takes 8-12 hours round trip — shorter than Everest’s 14-18 hours but still demanding at extreme altitude.
Lhotse South Face
The Lhotse South Face is one of the most formidable climbing objectives on any 8,000m peak — a 3,300m vertical wall rising from the Chukhung valley on the opposite side of the mountain from the standard route. The face has been the scene of many failed attempts, significant fatalities, and very few successful ascents. It is not a commercial climbing objective and is reserved for elite alpinists pursuing specific career-defining objectives.
The South Face became infamous in 1989 when Jerzy Kukuczka — the second person in history to complete all 14 eight-thousanders (after Reinhold Messner) — died on the face during a new-route attempt. Kukuczka fell when a rope broke while leading a difficult pitch above 8,200m on October 24, 1989. His death was a profound loss for Polish mountaineering and for the broader climbing community. The face’s reputation as a widow-maker was reinforced by multiple other fatal attempts in subsequent decades.
Tomo Cesen’s claimed solo ascent of the South Face in 1990 was later considered unverified by the climbing community, adding to the face’s mythology. A verified Russian expedition summited via the South Face in 1990. Subsequent ascents have been infrequent. The face requires sustained extreme-difficulty climbing at altitudes above 8,000m — the kind of sustained technical effort that pushes the edge of what is humanly possible in Himalayan mountaineering. Climbers researching the South Face should understand this is not a realistic commercial objective. This guide’s practical recommendations all assume the standard West Face route.
Lhotse Shar & Lhotse Middle
The Lhotse massif contains four distinct summits, three of which are above 8,000m. Lhotse Shar (8,383m) is the easternmost summit and was first climbed May 12, 1970, by Austrians Sepp Mayerl and Rolf Walter via the southeast ridge. Lhotse Shar sees occasional commercial activity and has been climbed several times over the decades, though it is significantly less popular than Lhotse Main.
Lhotse Middle (8,414m) was the most technically interesting subsidiary because it remained the highest unclimbed named peak on Earth until May 23, 2001, when a Russian expedition (Eugeny Vinogradsky, Sergei Timofeev, Alexei Bolotov, and Petr Kuznetsov) completed the first ascent via a technical traverse. The Russian ascent was one of the last major “first ascents” in 8,000m climbing. Lhotse Middle is essentially never climbed commercially — it requires a technical traverse that combines Lhotse Main and Lhotse Middle into a single complex objective.
For commercial climbers, these subsidiary summits are not alternatives to Lhotse Main — they are separate and more technical objectives. Climbers researching “climbing Lhotse” in the commercial sense are referring to Lhotse Main, and this guide’s logistics, costs, and planning advice all assume Lhotse Main as the objective.
2026 Lhotse Permits, Fees & Nepal Regulations
Lhotse climbing permits are administered by the Nepal Department of Tourism through the same framework that governs all of Nepal’s 8,000m peaks. The 2026 permit structure reflects the significant fee increase that took effect on September 1, 2025, with Lhotse’s spring permit rising from $1,800 to $3,000 — a 67% increase matching the proportional hike applied to all Nepal 8,000m peaks except Everest (which jumped from $11,000 to $15,000).
Effective September 1, 2025, Nepal raised climbing permit fees for all 8,000m peaks. Lhotse’s spring permit rose from $1,800 to $3,000 per climber — a 67% increase matching the proportional hikes applied to Kangchenjunga, Makalu, Manaslu, Dhaulagiri, and Annapurna I. Everest’s fee rose from $11,000 to $15,000 in the same announcement. Nepal cited safety, environmental protection, overcrowding management, and rescue infrastructure funding as justifications. The new fees are considered final for 2026 — expeditions applying now should budget the updated rates.
2026 Lhotse Permit Fees
Foreign climbers:
- Spring (March-May): $3,000 per climber — the overwhelming majority of Lhotse permits are issued in this category
- Autumn (September-November): $1,500 per climber — rare attempts
- Winter (December-February) & Monsoon (June-August): $750 per climber — specialized attempts only
Nepali climbers: Reduced rates proportionally lower than foreign fees, typically NPR 50,000-75,000 for spring ($400-600 equivalent).
Everest-Lhotse Combined Permits
Climbers pursuing both Everest and Lhotse in a single season must obtain separate permits for each peak — Nepal does not offer a combined Everest-Lhotse permit. The combined permit cost for 2026 is $15,000 (Everest) + $3,000 (Lhotse) = $18,000 in permit fees alone. Many operators building Double Crown expeditions include both permits in their package pricing, which is why combined Everest-Lhotse expeditions typically cost $70,000-$120,000+ total.
Key Regulatory Requirements
Beyond the permit fee, several Nepal regulations govern 8,000m expeditions:
- Permit validity: 55 days from issuance (reduced from the previous 75-day window per 2025 regulatory changes)
- Mandatory licensed guide: 1 guide per 2 climbers required on peaks above 8,000m since 2025
- Liaison officer: Nepal government Liaison Officer accompanies each expedition
- GPS tracking: Climbers required to carry GPS tracking devices per 2025 regulations
- Biodegradable waste bags: Mandatory for human waste — enforcement intensified in the Everest/Lhotse region after 2024 poo bag requirements
- Insurance requirements: Climbers must carry insurance with evacuation coverage; Sherpa and porter staff must be insured through the expedition operator
- Sagarmatha National Park entry fee: Separate fee for the national park covering the Everest region (approximately NPR 3,000-6,000)
- SPCC Icefall Doctor fee: Shared among all Everest-region expeditions using the Khumbu Icefall — this covers the rope-fixing and maintenance work that Lhotse climbers depend on
- Environmental deposits: Expeditions must provide environmental/garbage deposits refunded upon verified cleanup
Access Logistics
Lhotse uses identical access infrastructure to Everest because it shares Base Camp:
- International flight to Kathmandu: Tribhuvan International Airport
- Domestic flight Kathmandu → Lukla: 30-minute flight to Tenzing-Hillary Airport (frequently cancelled due to weather; often takes multiple attempts)
- Lukla → Everest Base Camp: 8-10 day trek through Phakding, Namche Bazaar, Tengboche, Dingboche, Lobuche, and Gorak Shep to Base Camp at 5,364m
The approach is one of the most popular trekking routes in the world and is well-established with numerous tea houses, lodges, and support services. The quality of the approach is actually higher than for most 8,000m peaks — a significant benefit of Lhotse’s Everest-adjacent location.
Lhotse Expedition Costs in 2026
Lhotse is significantly cheaper than Everest despite sharing infrastructure — the lower permit fee ($3,000 vs $15,000) drives most of the savings, with additional reductions from fewer oxygen bottles, simpler summit-push logistics, and smaller Sherpa teams. Lhotse is generally the most affordable way to climb an 8,000m peak in the Everest region.
Standard Expedition: $30,000–$55,000
A standard commercial Lhotse expedition in 2026 costs $30,000-$55,000 per climber for a full 6-8 week program. This tier includes the $3,000 permit, Liaison Officer fees, Base Camp services with meals and tents, fixed lines and group equipment, Icefall Doctor fee contribution, Sherpa support (typically 1:2 ratio), basic oxygen supply (4-5 bottles), and logistics management. Operators in this tier include Nepali outfitters with strong Khumbu region experience.
Premium Expedition: $55,000–$80,000
Premium Lhotse operators charge $55,000-$80,000 for enhanced expeditions featuring higher Sherpa ratios (often 1:1), more oxygen bottles (5-7), Western guides on the expedition, superior Base Camp amenities with private tents and heated dining, enhanced safety protocols with satellite communication arrays, and smaller team sizes. Operators in this tier include Adventure Consultants, Himalayan Experience (Himex), Seven Summit Treks, Madison Mountaineering, Alpenglow Expeditions, Elite Exped, 8K Expeditions, and Imagine Nepal.
Everest-Lhotse Double: $70,000–$120,000+
Combined Everest-Lhotse Double Crown expeditions cost $70,000-$120,000+ and require premium operator support. These expeditions typically include both permits ($18,000 combined), extensive oxygen supply (7-10 bottles), 1:1 Sherpa ratios, extended Base Camp duration, and specialized support for the compressed summit sequence. Only a handful of operators offer true Double Crown programs, and most require extensive verification of client capability before acceptance.
Additional Required Costs Beyond Expedition Fee
- Personal gear: $5,000-$12,000 (8,000m boots, down suit, technical climbing equipment)
- International flights to Kathmandu: $1,200-$2,500 round trip
- Travel insurance with high-altitude coverage: $800-$2,500 (critical given Khumbu Icefall exposure)
- Pre/post-climb Kathmandu hotels: $300-$800
- Tips for Sherpa and support staff: $800-$1,800 (higher for Double Crown)
- Personal communications (satellite phone rental): $300-$800
- Supplemental oxygen (if using beyond included): $400-$600 per bottle
- National park fees & local taxes: $100-$300
Total realistic Lhotse expedition budget: $40,000-$65,000 (standard), $65,000-$90,000 (premium), $90,000-$140,000+ (Everest-Lhotse Double).
Lhotse Gear Checklist
Lhotse gear requirements largely mirror Everest because of the shared infrastructure, with slight adjustments for the shorter summit day and technical terrain in the Reiss Couloir. Every climber should have robust 8,000m-rated equipment throughout — the shared Icefall and Lhotse Face do not forgive underprepared gear.

The Lhotse Face: The Defining Feature of Both Lhotse and Everest
No feature is more central to Everest-region climbing than the Lhotse Face — the massive wall of glacial blue ice that every Everest and Lhotse climber must ascend. Understanding the Lhotse Face is essential to understanding how both mountains are climbed.
What the Lhotse Face Is
The Lhotse Face is a 1,125-meter (3,690 ft) wall of glacial blue ice forming the western flank of Lhotse. It rises at sustained 40-55 degree pitches with occasional 80-degree bulges — creating one of the most iconic and demanding climbing features in world mountaineering. The face connects the floor of the Western Cwm at approximately 6,400m to the ridge system at approximately 7,500m where both the South Col (for Everest) and the upper Lhotse route branch off.
Two Critical Rocky Interruptions
Two named rocky features interrupt the Lhotse Face’s otherwise pure ice character:
- The Yellow Band — a prominent band of sedimentary rock (marble and phyllite) around 7,500m that gives the feature its distinctive yellowish color. The Yellow Band is where the Lhotse and Everest routes diverge — Everest climbers traverse left above the Yellow Band toward the Geneva Spur, while Lhotse climbers continue right up the steeper face.
- The Geneva Spur — a rocky rib above the Yellow Band that Everest climbers cross to reach the South Col. Lhotse climbers do not typically cross the Geneva Spur — they continue up the face instead.
Climbing the Lhotse Face
The Lhotse Face climbing technique is defined by fixed-line work. Climbers use jumars to ascend fixed ropes placed by Sherpa rope-fixing teams each season. The ice is generally hard blue ice that accepts crampon placements well, but the sustained angle demands efficient technique — climbers who struggle with jumar rhythm at altitude lose enormous amounts of energy on the face. The typical pattern is: jumar up 20-30 meters, pause to breathe, jumar again. Most climbers take 4-6 hours to climb from Camp 2 to Camp 3 during acclimatization rotations, and the summit push adds additional hours.
Hazards on the Lhotse Face
The Lhotse Face is not safe despite being the standard acclimatization zone for both Everest and Lhotse:
- Serac fall: Hanging glaciers above the face can release ice without warning. The 2016 death of Ang Furba Sherpa on the face is one example of Lhotse Face fatalities; there have been many others across decades.
- Rockfall: The Yellow Band area has produced rockfall incidents, especially in warm afternoons.
- Fall risk: The sustained steep angle means any unroped fall is catastrophic. Fixed-line discipline is absolute.
- Crowding bottlenecks: On summit day, large numbers of Everest and Lhotse climbers simultaneously ascend the face — creating bottlenecks at anchors and transitions.
- Exhaustion-related accidents: Descent after summit day, with climbers exhausted and potentially oxygen-depleted, has produced multiple accidents over the decades.
Experienced Everest-region climbers treat the Lhotse Face with the same respect they give the Khumbu Icefall. It is not a practice slope or a warmup — it is serious 7,000m+ climbing terrain that demands full technical competence.
Lhotse Safety, Mortality & Why Its Death Rate Is Lower Than K2
Lhotse’s historical death rate of approximately 5-6% is significantly lower than K2’s 20-25% or Kangchenjunga’s 20-22%, but still substantially higher than Everest’s 1-3%. Understanding why Lhotse sits in this middle category helps climbers assess risk realistically.
Lhotse Mortality Statistics
Through early 2026, approximately 60+ climbers have died on Lhotse against roughly 900+ successful summits — a death rate of approximately 5-6%. Lhotse mortality patterns:
- Khumbu Icefall deaths: Shared with Everest expeditions, the Icefall has produced multiple Lhotse-related deaths over the decades, including during the catastrophic 2014 avalanche that killed 16 Nepali workers
- Lhotse Face fatalities: Serac fall, rockfall, and falls on fixed lines have claimed climbers over the years, including Ang Furba Sherpa in 2016
- South Face disasters: Jerzy Kukuczka in 1989 and others on the extreme South Face (not counted in standard commercial climbing statistics)
- Reiss Couloir incidents: The narrow summit couloir has produced falls and exhaustion-related deaths, though these are less common than other zones
- Altitude illness: HAPE and HACE account for a portion of Lhotse deaths, often precipitated by pushing through warning signs due to Everest-adjacent proximity
Why Lhotse Is Safer Than K2 and Kangchenjunga
Lhotse’s lower death rate reflects several structural factors:
- Shared Everest infrastructure: The Khumbu Icefall Doctors maintain the lower route, fixed lines are typically well-established by the time Lhotse climbers arrive, and helicopter rescue is available up to approximately 7,200m
- Shorter summit day: 8-12 hours from Camp 4 vs K2’s or Kangchenjunga’s 15-18 hours means less cumulative death-zone exposure
- Lower summit altitude: 8,516m vs K2’s 8,611m or Kangchenjunga’s 8,586m makes a meaningful physiological difference
- Better rescue response: Everest Base Camp’s medical infrastructure (Himalayan Rescue Association clinic, multiple helicopter operators) benefits Lhotse climbers equally
- Mature commercial operations: Operators running Lhotse expeditions have decades of Everest-region experience to draw on
Why Lhotse Is More Dangerous Than Everest
Despite sharing infrastructure, Lhotse is genuinely more dangerous than Everest because:
- Technical terrain above Yellow Band: The upper Lhotse Face and Reiss Couloir are steeper and more technical than Everest’s South Col route
- Narrower commercial experience: Fewer operators have deep Lhotse-specific experience compared to Everest
- Smaller Sherpa teams: Typical 1:2 ratios vs Everest’s 1:1 at premium tiers
- Less redundancy in fixed lines: Above the divergence point, Lhotse has less shared rope-fixing infrastructure
- Icefall Doctor work primarily serves Everest: Lhotse-specific hazards may receive less attention if Everest concerns dominate
Safety Principles for Lhotse
Experienced Lhotse climbers emphasize these principles:
- Respect the Icefall every crossing. Each Khumbu Icefall crossing carries risk — don’t become complacent after the 3rd or 4th time through
- Maintain fixed-line discipline on the Lhotse Face. Even experienced climbers have died from unclipping momentarily at transitions
- Plan Camp 4 timing carefully. Unlike Everest’s South Col which has multiple teams establishing camps, Lhotse Camp 4 often has fewer teams — ensure your operator has the tent infrastructure in place before you arrive
- Assess Reiss Couloir conditions pre-summit push. If conditions are marginal, don’t push through — the couloir has turned capable teams back many times
- Coordinate with Everest traffic on summit day. Large combined populations create bottlenecks; plan timing to avoid peak Everest crush where possible
- Reserve energy for the descent. Lhotse’s descent back through the Reiss Couloir, down the Lhotse Face, and through the Khumbu Icefall demands as much attention as the ascent
When to Climb Lhotse
Lhotse’s climbing calendar matches Everest’s because of the shared infrastructure — spring is the overwhelming standard season, with autumn seeing minimal activity and winter reserved for extreme specialized attempts.
Spring (Late April–May): Primary Season
Virtually all successful Lhotse summits occur between late April and late May. Climbers typically arrive at Base Camp by mid-to-late April, use late April for acclimatization rotations through the Khumbu Icefall and up the Lhotse Face, and target summit windows opening between May 10 and May 25 as the jet stream lifts off the Everest massif. The 2025 season produced strong summit activity in mid-May with multiple teams summiting on or around May 15, and the notable Everest-Lhotse Double Crown attempt by Jocelyn Cayer and Ashish later in the month.
Because Lhotse shares its season with Everest, climbers benefit from the heavily-worked fixed-line infrastructure established by Everest rope-fixing teams, the Icefall Doctor maintenance of the Khumbu Icefall, and the shared weather forecasting resources across the Everest-Lhotse population. The downside is crowding — Nepal typically issues 450-500+ Everest permits plus 50-100 Lhotse permits, creating significant foot traffic through shared terrain.
Autumn (September–October): Minimal Climbing
Post-monsoon autumn sees occasional Lhotse attempts but nothing like spring’s volume. The monsoon leaves the route heavily snow-loaded, increasing avalanche risk on the Lhotse Face. Shorter daylight and rapidly cooling temperatures compress the viable climbing window. Some operators offer autumn Lhotse programs for climbers seeking lower-crowd experiences, but success rates are lower and the infrastructure benefits of spring are largely absent.
Winter (November–February): Elite Specialized Only
Winter Lhotse was first climbed by Krzysztof Wielicki solo on December 31, 1988. Subsequent winter attempts have occurred but the peak remains rarely climbed in winter. Conditions bring temperatures below -40°C, jet stream winds routinely exceeding 200 km/h, and extreme cold combined with limited daylight. Winter Lhotse is not a commercial opportunity.
Monsoon (June–August): No Climbing
Monsoon season climbing is impossible due to continuous precipitation and extreme avalanche risk on the Lhotse Face.
Realities of the Summit Window
Key considerations for Lhotse summit timing:
- Window structure: Lhotse tends to see 2-4 viable summit windows (2-4 days each) across the mid-to-late May period
- Coordination with Everest: Summit windows are typically shared with Everest, so climbers must plan around peak-traffic days
- Icefall Doctor maintenance: Fixed lines and ladder infrastructure are maintained throughout the season; Lhotse climbers benefit from this shared work
- Jet stream lift: Summit windows open when the jet stream lifts above 8,500m, typically by May 10-15
- Monsoon arrival: Windows close as monsoon precipitation arrives, typically by late May or early June
- Ready-state required: Full acclimatization completed through rotations is essential — teams still rotating when windows open often miss them
Five Notable Lhotse Expeditions from 2025
The 2025 Lhotse season produced a revealing cross-section of modern Everest-region climbing — from large commercial teams to small independent pushes and the rare Everest-Lhotse Double Crown attempt. Here are five expeditions from 2025 that illustrate the realities of climbing the fourth-highest mountain.
Imagine Nepal Summit Team
Summit ReachedImagine Nepal reported successful Lhotse summits in May 2025, including Lin Zhiyong and Dipan Gurung. Their climb reflected the value of moving efficiently from the South Col, using favorable timing, and staying disciplined on steep terrain where momentum and control both matter. Imagine Nepal has been expanding their Lhotse programs in recent years, building on their broader Himalayan operational experience.
Climbing the Seven Summits Team
Summit ReachedClimbing the Seven Summits reported multiple Lhotse summits on May 15, 2025, with all members safely back at the South Col. Their result highlighted how important it is to treat the summit and return as one continuous effort rather than spending too much energy on the way up. The May 15 window aligned with strong spring conditions on the Everest-Lhotse massif.
Everest to Lhotse Double Objective Team
Double Crown AttemptThe 2025 season produced one of the better-documented Double Crown attempts by Jocelyn Cayer and Ashish, attempting to summit Everest and Lhotse within 24 hours — the rare feat sometimes called the Double Crown. The team used the South Col approach with a Lhotse Couloir finish, demonstrating that ambition only works when recovery is still strong enough for Lhotse’s technical terrain after an Everest summit. The effort highlighted both the possibilities and the extreme demands of sequential 8,000m summits.
Small Independent Push from the South Col
Summit ReachedSmaller Lhotse teams in 2025 faced the same steep upper route but with less built-in margin for delay, fatigue, or slow movement. This style of climb rewarded climbers who were already well acclimatized, technically comfortable, and realistic about how hard the final couloir can feel after a long expedition. Key themes: smaller team with less room for mistakes, steep upper route demanded focused movement, energy conservation was critical above Camp 4, and safe descent remained the main priority throughout the push.
Late-Season Lhotse Attempt Cut Short
Turned BackNot every 2025 Lhotse effort ended on the summit. The mountain continued to remind climbers that steep terrain above the South Col exposes weak pacing, poor recovery, and late decision-making quickly. A late-season attempt was cut short due to the combination of fatigue, timing, and deteriorating conditions in the Reiss Couloir. Turning around remained one of the strongest decisions available — a reminder that discipline is part of the skill set that makes Lhotse climbers successful across seasons.
What Climbers Learned on Lhotse in 2025
Beyond individual expedition outcomes, the 2025 season produced several practical lessons that apply across styles and approaches:
Do not treat Lhotse like a quick Everest add-on. One of the clearest 2025 lessons is that Lhotse deserves full respect as its own summit objective. Climbers would likely say they would budget more recovery, more focus, and more humility for the upper mountain. The assumption that Lhotse is “Everest without the summit ridge” misses that the Reiss Couloir is technically harder than anything on Everest’s South Col route.
Arrive at the South Col with more in reserve. Lhotse’s steep final terrain can punish climbers who have already spent too much energy lower down. A strong 2025 takeaway is that pacing and energy conservation matter as much as raw fitness. Climbers who pushed too hard during Khumbu Icefall rotations or on the Lhotse Face found themselves depleted when the technical summit day demanded strength.
Summit day stays technical when you are tired. The upper couloir does not become easier just because the weather is good. Climbers in 2025 would likely say they learned to keep movement clean, efficient, and deliberate even after long hours at altitude. Fatigued technique compounds across hours of effort, and the Reiss Couloir does not forgive sloppy movement at 8,300m.
Descent discipline is part of success. Several successful 2025 Lhotse climbs emphasized getting safely back to the South Col area before declaring success. Climbers would do well to think of the summit as the halfway point and protect enough focus and strength for the way down. The descent through the Reiss Couloir and upper Lhotse Face demands full attention even when climbers are exhausted from the summit push.
Choose timing carefully. Lhotse rewards teams that line up their summit day with good conditions and solid recovery. A rushed push can leave climbers too depleted for the most serious terrain near the top. The 2025 season saw better outcomes for teams that waited for truly stable windows rather than pushing on marginal days.
Turning around is still a strong decision. The strongest climbers are often the ones willing to stop before a manageable day becomes a dangerous one. Lhotse in 2025 reinforced that judgment is one of the most valuable summit skills — the late-season turnaround climbers made calls that preserved their health and capacity for future expeditions.

Frequently Asked Questions About Climbing Lhotse
How hard is Lhotse compared to Everest?
Lhotse is technically more demanding than Everest above the Yellow Band, despite being 332 meters shorter. Through the Khumbu Icefall and Western Cwm, climbers on Lhotse follow the exact same route as Everest climbers — they share Base Camp, share the Icefall fixed lines, and share Camps 1, 2, and much of Camp 3 on the Lhotse Face. The routes diverge at approximately 7,400m above the Yellow Band, where Everest climbers traverse left toward the Geneva Spur and South Col while Lhotse climbers continue right up the steeper upper Lhotse Face into the narrow Reiss Couloir leading directly to Lhotse’s summit at 8,516m. The Reiss Couloir is narrower, steeper, and more technically demanding than Everest’s summit ridge — it involves sustained climbing in a confined couloir with rockfall exposure and ice conditions that vary significantly by year. However, Lhotse’s summit death rate is approximately 5-6% historically, far lower than K2’s 20-25% but higher than Everest’s 1-3%. Climbers who have completed Everest often find the Lhotse summit day’s final 1,000m of vertical gain technically harder than anything on Everest’s South Col route.
How much does it cost to climb Lhotse in 2026?
A commercial Lhotse expedition costs $30,000 to $55,000 in 2026, with premium operators charging $55,000-$80,000 and combined Everest-Lhotse expeditions running $70,000-$120,000+. The 2026 Lhotse permit fee for foreign climbers is $3,000 for spring (March-May), up from $1,800 before September 1, 2025 when Nepal raised fees across all 8,000m peaks. Autumn permits are approximately $1,500, winter permits approximately $750. Beyond the permit, climbers face Nepali Sherpa fees ($8,000-$15,000 per private Sherpa), oxygen systems ($2,500-$5,000 for 4-6 cylinders), Icefall Doctor fees (SPCC) shared with other Everest-region expeditions, garbage and environmental deposits, Lukla flights, the 8-10 day trek to Everest Base Camp, insurance with evacuation coverage ($1,500-$4,000), and the mandatory liaison officer. Total realistic Lhotse budget: $40,000-$70,000 standard, $65,000-$100,000 premium. Lhotse is typically 30-50% cheaper than Everest because it skips the highest camps and summit-specific logistics, making it popular for climbers seeking an 8,000m summit on a tighter budget.
How long does a Lhotse expedition take?
A complete Lhotse expedition takes 6-8 weeks from arrival in Nepal through final descent, matching the Everest timeline because the two mountains share infrastructure. Typical timeline: Days 1-3 arrive Kathmandu, fly to Lukla (weather permitting). Days 4-11 trek to Everest Base Camp via Namche Bazaar, Tengboche, and Dingboche — the same approach as Everest climbers. Weeks 3-5 acclimatization rotations through the Khumbu Icefall into the Western Cwm, with climbs to Camp 1 at 5,943m, Camp 2 at 6,400m, and touches to Camp 3 at 7,200m on the Lhotse Face. Weeks 6-7 weather watching at Base Camp for summit windows in May. Summit push from Base Camp through Camp 2, Camp 3, Camp 4 (typically at the top of the Lhotse Face around 7,900-8,000m), and the final summit day via the Reiss Couloir. Descent back through Base Camp and return to Lukla. Lhotse can be slightly faster than Everest if climbers are well-acclimatized and efficient since it skips Camp 4 at the South Col and the Everest summit push — though most operators run similar timelines either way.
What is the Lhotse Face?
The Lhotse Face is a massive wall of glacial blue ice approximately 1,125 meters (3,690 ft) tall that forms the western flank of Lhotse. It rises at 40-55 degree pitches with occasional 80-degree bulges, creating one of the most iconic climbing features in Himalayan mountaineering. Both Everest and Lhotse climbers must ascend the Lhotse Face — Everest climbers use it to reach the Geneva Spur and South Col, while Lhotse climbers climb further up the face into the Reiss Couloir leading directly to Lhotse’s summit. Two rocky sections interrupt the ice: the Yellow Band (a prominent band of sedimentary rock around 7,500m where the Everest and Lhotse routes diverge) and the Geneva Spur (a rocky rib that Everest climbers cross to reach the South Col). Climbing the Lhotse Face requires sustained fixed-line work with jumars, good crampon technique on ice, and careful rope discipline. The face is exposed to serac fall from hanging glaciers above, and ice conditions vary significantly from year to year. Camp 3 is typically established partway up the face around 7,200m, making this the critical acclimatization zone for both Everest and Lhotse climbers.
Who was the first to climb Lhotse?
Swiss climbers Ernst Reiss and Fritz Luchsinger were the first to reach the summit of Lhotse on May 18, 1956 at 2:50 PM, as part of the Swiss Everest-Lhotse Expedition led by Albert Eggler. The team reached Camp VI high on the northwest face, and Reiss and Luchsinger made the final push through the narrow couloir that now bears Reiss’s name — the Reiss Couloir — which leads directly to Lhotse’s summit ridge. Six days later, on May 24, 1956, the same Swiss expedition made the second ascent of Mount Everest (Jürg Marmet and Ernst Schmied), with a third Everest ascent the following day by Hans-Rudolf von Gunten and Adolf Reist. The 1956 expedition thus became the first to summit both Everest and Lhotse in a single season — a significant logistical and climbing achievement at the time. Fritz Müller of the expedition also completed scientific glaciological observations that contributed to Himalayan ice research. The first winter ascent of Lhotse came 32 years later on December 31, 1988 by Polish climber Krzysztof Wielicki — who completed the climb solo, one of the most notable achievements in winter Himalayan mountaineering.
Can a beginner climb Lhotse?
Lhotse is not a beginner mountain despite being the cheapest and most accessible 8,000m peak after Manaslu and Cho Oyu. The Khumbu Icefall alone is one of the most dangerous features in commercial climbing, and the Lhotse Face requires sustained fixed-line work at extreme altitude. Minimum recommended prerequisites: multiple successful 6,000-7,000m summits (Island Peak, Ama Dablam, Baruntse, Himlung Himal are common), proven ability to move safely through icefall terrain with fixed ladders, strong jumar and descender technique on steep fixed lines, comfortable movement on 40-55 degree ice, cold-weather endurance below -30°C, and mature decision-making under oxygen-depleted conditions. Lhotse is often climbed as a ‘first 8,000m peak’ by experienced 7,000m climbers, particularly those targeting the 14 eight-thousanders or using Lhotse as Everest preparation. It’s generally considered slightly easier than Everest overall because the summit day is shorter and the route spends less time in the extreme death zone, but the technical climbing in the Reiss Couloir is harder than anything on Everest’s trade route. Climbers without any 8,000m experience should build through one lower-altitude 8,000m peak like Cho Oyu or Manaslu before attempting Lhotse.
What is the Reiss Couloir?
The Reiss Couloir is a narrow steep ice couloir on Lhotse’s upper northwest face, named for Swiss climber Ernst Reiss who (with Fritz Luchsinger) used it to make the first ascent on May 18, 1956. The couloir cuts upward through the face from approximately 7,600m to just below Lhotse’s summit at 8,516m, providing the only practical line to the top for commercial climbers. The Reiss Couloir features sustained 50-60 degree ice with occasional steeper sections, narrow passages where only one climber can move at a time, and exposure to rockfall and serac hazards from the surrounding faces. Summit day climbers enter the couloir after traversing right off the main Lhotse Face above the Yellow Band, ascend through the couloir for several hundred meters, and exit near the summit cone for the final summit push. The couloir can vary significantly in character from year to year — some seasons it is almost entirely ice requiring crampons and ice tools, while other seasons it has significant mixed rock-and-ice climbing that increases difficulty. Conditions in the couloir are one of the key factors operators watch when assessing Lhotse summit feasibility each season, and the route has turned back otherwise-capable expeditions when couloir conditions were deemed too dangerous.
When is the best time to climb Lhotse?
Late April through May is the overwhelming best time to climb Lhotse, matching Everest’s primary spring season. The pre-monsoon spring offers the best combination of settled weather, climbable conditions through the Khumbu Icefall, and stable high-altitude weather windows. Summit windows typically open between May 10 and May 25 as the jet stream lifts off the Everest massif. The 2025 season produced multiple summit days in mid-May including a strong window around May 15 when multiple commercial teams reached the top. Because Lhotse shares infrastructure with Everest, the spring crowds are significant — Everest typically issues 450-500+ permits in spring and Lhotse adds another 50-100. The combined Everest-Lhotse population creates logistical pressures through the Khumbu Icefall. Autumn attempts (September-October) are rare but possible; some operators occasionally offer autumn Lhotse programs. Winter Lhotse has been climbed only once — December 31, 1988 by Krzysztof Wielicki — and is reserved for elite specialized mountaineers. Monsoon season (June-August) is not climbable. Climbers should arrive at Base Camp by mid-April to allow full acclimatization through multiple Khumbu Icefall rotations before summit windows open.
What is the Everest-Lhotse double crown?
The ‘Double Crown’ or ‘Everest-Lhotse Double’ refers to the rare achievement of summiting both Mount Everest and Lhotse in a single season — or in the most elite version, within 24 hours. Because the two mountains share the same Base Camp, Khumbu Icefall, Western Cwm, and Lhotse Face up to approximately 7,400m, experienced climbers with extensive 8,000m preparation occasionally attempt both summits during one spring expedition. The compressed version attempts the double in under 24 hours: summit Everest via the South Col, descend back to the South Col area, then traverse to Camp 4 on the Lhotse side and push to Lhotse’s summit. The most recent well-documented 2025 attempt was by Jocelyn Cayer and Ashish. The double crown is extraordinarily demanding — it requires exceptional fitness, optimal weather in a narrow window, strong Sherpa support for both summits, and the ability to perform at the limits of human capacity at extreme altitude for an extended period. Most climbers who attempt the double take several days between the two summits rather than the 24-hour compressed version. Combined Everest-Lhotse programs cost $70,000-$120,000+ and are offered by several premium operators for climbers with appropriate experience.
Which Lhotse route is the standard commercial route?
The West Face route via the Khumbu Icefall, Western Cwm, Lhotse Face, and Reiss Couloir is the overwhelming standard commercial route on Lhotse, accounting for 95%+ of all successful summits. The route is essentially identical to Everest’s South Col route from Base Camp up to approximately 7,400m above the Yellow Band, where the two routes diverge — Everest climbers traverse left toward the Geneva Spur while Lhotse climbers continue right into the upper Lhotse Face and Reiss Couloir. The route was pioneered by the 1956 Swiss expedition and has been the standard commercial line ever since. The infamous Lhotse South Face — the 3,300m wall on the opposite side of the mountain — is one of the most technically difficult and dangerous climbs in the world, and has been climbed only a handful of times. Polish climber Jerzy Kukuczka died attempting the South Face in 1989. The South Face is essentially never attempted by commercial expeditions and is reserved for elite alpinists pursuing specific objectives. Lhotse Shar (8,383m) and Lhotse Middle (8,414m) are separate subsidiary summits that are occasionally climbed but count as distinct achievements rather than alternatives to the main Lhotse summit.
