Manaslu Climb Guide: Routes, $3,000 Permit & the True Summit Controversy (2026)
Manaslu is the world’s 8th-highest peak and statistically one of the safer 8000ers — but the same conditions that make it commercially accessible also produced two of the most lethal Himalayan avalanches in modern history (11 dead in 2012, 2 dead in 2022). Plus the famous “true summit” controversy: for 65 years climbers were summitting the foresummit. Here’s the verified 2026 expedition planning data.
The History of Manaslu
Manaslu’s name derives from the Sanskrit word manasa, meaning “intellect” or “soul.” The mountain is also called Kutang in the local Nepali tongue, after a region of the Tibetan-Buddhist communities that surround it. It rises above the Budhi Gandaki river valley in central Nepal’s Gorkha District, roughly 64 km east of the Annapurna massif.
1950: Tilman Reconnaissance
British alpinist H.W. “Bill” Tilman led the first reconnaissance of the Manaslu region in 1950 during his historic Nepal Himalayan expedition. Tilman’s party photographed and documented Manaslu, providing the first detailed Western knowledge of the mountain. Japanese expeditions arrived shortly after.
1952-1955: Japanese Reconnaissance and Hostility
The Japanese Alpine Club, sponsored by the Mainichi Press, sent a five-member reconnaissance team to Manaslu in 1952 under the leadership of Dr. K. Imanishi. They explored the western approach via the Marsyandi valley but found it impractical due to a “tremendously steep wall of about 15,000 ft.” A 1953 Japanese attempt reached high on the northeast side. A 1954 attempt was forced back. Local hostility developed: after a 1954 avalanche destroyed a monastery and killed 18 villagers, locals believed the climbers had angered the mountain gods, and Japanese expeditions were blocked for over a year before returning in 1956.
9 May 1956: First Ascent
The 1956 Japanese expedition, led by Yuko Maki, fielded a 12-member team supported by sirdar Gyalzen Norbu (who had already summited Makalu with the French in 1955). They established Camp VI at 7,800m. On 9 May 1956, Toshio Imanishi and Gyalzen Norbu Sherpa made the first ascent. Two days later, Kiichiro Kato and Minoru Higeta reached the same point on 11 May 1956.
The 65-year summit controversy: Imanishi described seeing “two snow peaks on the right and a triangular rock pinnacle on the left” beyond his summit point. For decades, the climbing community assumed this was the true summit. It wasn’t. In 2020, mountaineering writer Mark Horrell and German climbing journalist Stefan Nestler began documenting the discrepancy. In 2021, Mingma Gyalje Sherpa (“Mingma G”) of Imagine Nepal Treks led a team to what was confirmed as the true summit. Team member Jackson Grove’s drone imagery showed a clear height disparity between the foresummit climbers had been using and the true summit ridge beyond it. In autumn 2022, Elite Exped’s Sherpa team became the first to fix ropes to the true summit, opening it to commercial teams. The Himalayan Database now requires climbers to reach the ridge point to count as a true Manaslu summit — though it has retained pre-2022 historical records as “summits.”
1971: Northwest Wall
The first ascent of the precipitous and dangerous Manaslu Northwest Wall of rock and ice was completed on 17 May 1971 by Kazuharu Kohara and Motoyoshi Tanaka, part of an 11-man Japanese team.
1972: Messner’s South Face
On 25 April 1972, Reinhold Messner made the third ascent of Manaslu overall via the South Face to West Ridge — his second 8000er. The expedition ended in tragedy when a fierce storm caught teammate Franz Jäger, who had turned back, and he died of exposure before reaching high camp.
1974: First Woman to Climb an 8000er — On Manaslu
On 4 May 1974, Naoko Nakaseko, Masako Uchida, Mieko Mori, and Jambu Sherpa from a Japanese women’s expedition reached the summit. This was the first ascent of Manaslu by women — and the first ascent of any 8000-meter peak by a woman in history. A landmark for Himalayan mountaineering.
1984: First Winter Ascent
On 12 January 1984, Polish alpinists Maciej Berbeka and Ryszard Gajewski completed the first winter ascent of Manaslu — only the second winter ascent of any 8000er after Poland’s 1980 Everest winter climb.
1997: First American Ascent
Charlie Mace made the first American summit of Manaslu, demonstrating that the mountain remained a serious objective even decades after the first ascent.
The Two Avalanche Tragedies That Defined Modern Manaslu
September 23, 2012 — 11 dead. At 4:45 AM Nepal time, a large serac released above Camp 3 at 7,400m, triggering a slab avalanche that hit Camp 3 directly and impacted Camp 2 with a severe wind blast. Most of the 11 killed were sleeping in their tents. The avalanche followed 15 days of unceasing heavy snowfall — 5 to 6 feet of accumulated snow on the slope. Avalanche debris spread from 7,400m down to 6,300m. Russell Brice coordinated the helicopter rescue with Simrik Air. This remains one of the worst single-event tragedies in 8000-meter climbing.
September 26, 2022 — 2 dead. A second major avalanche struck between C3 and C4 at approximately 11:30 AM. American ski mountaineer Hilaree Nelson (49) — one of the most accomplished American climbers of her generation — was killed, along with high-altitude support climber Anup Rai (34). The 2022 tragedy was followed by another massive avalanche at base camp on October 1, 2022, that engulfed approximately 35 tents (no fatalities at base camp). Sherpa guide Dawa Chhiring Sherpa died in a separate higher-altitude avalanche the same morning. Multiple operators including Furtenbach Adventures and Madison Mountaineering withdrew their expeditions, ending what had been the busiest season ever on the mountain.
Lukas Furtenbach said at the time: “Heavy snowfall and no avalanche awareness or avalanche risk management — same as 2012.”

The Climbing Routes
Manaslu has four established climbing routes. Only the Northeast Face is commercially guided; the others are elite alpine-style objectives. There are no climbing routes from the Tibetan (north) side because the mountain sits entirely in Nepal.
| Route | First Ascent | Status | Notes |
|---|---|---|---|
| Northeast Face (Standard) | 9 May 1956 (Imanishi/Norbu) | ● Open · Standard | The 1956 Japanese route. ~98% of modern Manaslu summits. |
| Northwest Wall | 17 May 1971 (Kohara/Tanaka) | ● Open · Rare | “Precipitous and dangerous” rock and ice. Very rarely attempted. |
| South Face → West Ridge | 25 April 1972 (Messner) | ● Open · Elite Only | Messner’s third-ascent route. Serious alpine-style objective. |
| Northeast Buttress / Variations | Various | ● Open · Rare | Several variations on the NE face, including 2025 alpine-style attempts. |
Northeast Face — The Standard Route
Approach: The traditional approach is a 6–8 day trek from Soti Khola (or Arughat) through Machha Khola, Jagat, Deng, Namrung, Samagaon, and Samdo to Manaslu Base Camp at ~4,800m. Many 2025 expeditions now use helicopter fly-in to Samagaon Heliport, cutting the approach to 1–2 days.
Route character: From base camp, the route climbs onto the Manaslu Glacier with significant crevasse danger between C1 and C2. Above C2, the route navigates a serac-strewn section (the area of the 2012 and 2022 avalanches) before reaching C3 on the plateau below the North Col. Camp 4 sits at ~7,450m. From C4, the summit push climbs the steep snow ramp through the foresummit area to the true summit ridge.
Crux: Historically the crux was the C2–C3 serac zone (avalanche risk) and the final 50m to the true summit (the foresummit/true summit ridge, technical, corniced, and exposed). Since 2022, with fixed ropes to the true summit, the technical difficulty is well-managed for skilled climbers — but the avalanche risk in heavy-snow years remains unchanged.
Used by: All commercial 8000m operators (Furtenbach Adventures, Seven Summit Treks, Madison Mountaineering, Adventure Consultants, Imagine Nepal, 14 Peaks Expedition, Elite Exped).
Northwest Wall
Character: First climbed in 1971 by an 11-man Japanese team. The wall is rock and ice with significant objective hazard. Modern attempts are rare.
Key challenge: The wall is precipitous with sustained technical difficulty. Few teams attempt this route in modern era due to lower commercial demand and higher technical bar.
South Face / West Ridge — Messner’s Route
Character: Reinhold Messner’s 1972 route, the third ascent of Manaslu overall. The South Face is one of the largest faces in the Himalayas. Messner’s line traverses to gain the West Ridge for the final summit push.
Notable note: Messner’s teammate Franz Jäger died on the descent in a storm — a tragedy that shaped Messner’s later approach to climbing partners. A serious 2025 alpine-style ascent of the Southwest Face was reported by ExplorersWeb as one of the year’s top expeditions, indicating this terrain still attracts top alpinists.
Standard Route Camp Structure (Northeast Face)
Commercial expeditions establish four high camps above base camp. The camp structure has been refined since the 2012 and 2022 avalanche tragedies, with most operators now positioning Camp 3 at a lower elevation than the 1956–2010 era.
The post-2022 summit standard: A Manaslu summit now requires reaching the true summit ridge point, not the foresummit. Operators announce climbing programs as “to the true summit” or note this distinction. If your operator is vague about which summit they target, ask directly — it’s the difference between a recorded 8000er ascent and an asterisked one.
Permits, Fees & Logistics
Manaslu falls under Nepal’s Department of Tourism expedition permit category for peaks above 8,000m. Permit fees increased significantly effective September 1, 2025, with most non-Everest 8000ers (Kangchenjunga, Lhotse, Makalu, Manaslu) jumping from $1,800 to $3,000 in the dominant season.
Note on Manaslu’s seasonal pattern: Unlike most 8000ers which are spring-dominated, Manaslu is predominantly an autumn mountain. Per the Himalayan Database, of 775 historical expeditions through end of 2023, 568 were in autumn, 182 in spring, and only 24 in winter. The Manaslu Restricted Area Permit applies because the trek passes through a restricted border region.
| Item | Cost (USD) | Notes |
|---|---|---|
| Climbing permit — Autumn (Sep–Nov) | $3,000 per climber | Most popular Manaslu season; permit valid 55 days from issue |
| Climbing permit — Spring (March–May) | $3,000 per climber | Less common for Manaslu; same fee |
| Climbing permit — Winter (Dec–Feb) | ~$750 per climber | Discount but rare attempts |
| Manaslu Restricted Area Permit | $100 first 7 days + $15/day after | Required for the trek approach |
| Manaslu Conservation Area Permit (MCAP) | NPR 3,000 (~$25) | Conservation area fee |
| Annapurna Conservation Area Permit (ACAP) | NPR 3,000 (~$25) | Required if trek exits via Larke Pass |
| Garbage deposit | $300–500 (refundable) | Refunded on proof of waste-out |
| Liaison officer | $2,500–5,800 per expedition | Government-assigned; mandatory above 8,000m |
| Helicopter fly-in to Samagaon (optional) | $500–800 one-way | Increasingly popular alternative to 6–8 day approach trek |
| Budget guided expedition | $14,000–18,000 | Nepali-operated, basic logistics, partial oxygen |
| Mid-tier guided expedition | $22,000–32,000 | Western/Nepali combo, full oxygen, dedicated Sherpa |
| Premium guided expedition | $35,000–45,000+ | Furtenbach, Madison — high Sherpa ratios, weather forecasting, hyperbaric tents |
2025 regulation changes: Effective September 1, 2025, Nepal requires one guide per two climbers on all peaks above 8,000m. Solo and alpine-style expeditions are no longer permitted without special arrangement. GPS tracking and biodegradable waste bags are mandatory. Death repatriation insurance with minimum NPR 5 million (~$37,500) coverage is required.
Best Time to Climb & Weather Windows
Manaslu is the only commercial 8000er where autumn is the dominant season. The reason: spring outfitters concentrate resources on Everest, Annapurna, Dhaulagiri, and Makalu, leaving Manaslu’s logistics infrastructure better-supported in autumn. The 2025 season had a strong summit cycle starting 20 September after the rope-fixing team summited, with over 600 summits in a short span.
| Season | Window | Conditions | Watch For |
|---|---|---|---|
| Autumn | Mid-September – Mid-October | Dominant Manaslu season; ~73% of historical expeditions | Lingering monsoon snowfall; avalanche risk in heavy-snow years (2012, 2022) |
| Spring | April – Early May | ~24% of expeditions; less crowded but less route prep | Operator focus on Everest/Annapurna reduces Manaslu support |
| Winter | December – February | Brutal cold; ~3% of expeditions | Reserved for elite alpinists (1984 Berbeka/Gajewski first winter) |
| Monsoon | June – August | No commercial climbing | Continuous snowfall, avalanche, low visibility |
The autumn paradox: Manaslu’s autumn weather windows can be short and unpredictable because the climbing season starts as the monsoon ends. Late-monsoon snowfall, like the 15 days of continuous snow that preceded the 2012 disaster, creates avalanche conditions that don’t reliably stabilize. Modern operators (Furtenbach, Madison, Adventure Consultants) now coordinate snow assessment between teams before committing climbers to high camps. Ask your operator about their avalanche risk protocol — it’s the most important question on Manaslu.
Essential Gear Checklist
Manaslu gear requirements are standard 8000-meter expedition kit. The mountain is less technically demanding than K2 or Kangchenjunga but the cold/wind at the summit ridge demands top-tier insulation. Avalanche awareness gear is increasingly carried on Manaslu given recent history.
High-Altitude Clothing
- 8000m down suit OR expedition parka + down pants (-40°C rated)
- Base layers (3 sets), heavyweight fleece, windproof shell
- Expedition mitts + liner gloves (3 pairs)
- Balaclava + buff + goggles (2 pairs, including summit-clear lens)
- Glacier sunglasses (Category 4)
Boots & Foot Systems
- 8000m triple boots (La Sportiva Olympus Mons, Millet Everest, Scarpa Phantom 8000)
- Mid-altitude double boots for rotations
- Crampons with anti-balling plates (Petzl Lynx, Grivel G14)
- Multiple sock systems with vapor barrier
- Insulated overgaiters
Technical Hardware
- Harness (full strength, sized over down suit)
- Helmet (essential for serac-prone C2–C3 section)
- Ice axe + Whippet for descent
- Ascender + descender + 4 locking carabiners
- 2 prusik cords + 2 slings
Avalanche & Comms
- Avalanche transceiver (increasingly required by responsible operators)
- Headlamp + 3 spare battery sets (cold-rated lithium)
- Personal first-aid + frostbite prevention kit
- Garmin inReach Mini 2 or sat phone
- GPS device (mandatory under 2025 regulations)
Difficulty & Safety: What the Fatality Statistics Hide
Manaslu has approximately 2,172 historical summits and 88 deaths — a 1.49% fatality rate, making it the 7th safest of the 8 Tibet/Nepal 8000ers (only Cho Oyu is safer at 0.59%). This is one of the reasons Manaslu is so often recommended as a “first 8000er” or “Everest preparation peak.” But the aggregate statistic obscures three real risks specific to this mountain:
1. Avalanche cycles. The C2–C3 section funnels snow from massive serac fields above. In heavy-snow years (2012, 2022), this terrain becomes a death trap. Eleven climbers died at C3 in 2012 sleeping in their tents; Hilaree Nelson died near C4 in 2022. If your operator commits to high camps before the snowpack has stabilized, you are taking on the same risk profile as the climbers who died in those years.
2. The crevasse field between C1 and C2. Manaslu’s lower glacier is one of the more active icefall systems on a commercial 8000er. Crevasses shift season-to-season. The fixed-rope system requires diligent crampon technique. Multiple non-avalanche fatalities have occurred from crevasse falls on this section.
3. The “easy 8000er” trap. Manaslu’s reputation as a beginner-friendly 8000er attracts climbers with less experience than its actual difficulty warrants. Per Alan Arnette’s analysis, this is a recurring factor in deaths: climbers who summit Mont Blanc or Aconcagua then attempt Manaslu without the 6000m+ experience needed to handle exhaustion and decision-making at altitude.
The good news: When conditions are favorable and the avalanche cycle holds, Manaslu has high summit success rates. The 2025 autumn season demonstrated this — over 600 summits in a clean weather window. Choosing an operator with strong snow-assessment protocols and being willing to abort in a heavy-snow year (as Madison and Furtenbach did in 2022) substantially mitigates the avalanche risk.
Featured Expedition Operators
The operators below run established Manaslu programs. When evaluating, ask specifically about: avalanche risk protocol, oxygen strategy, summit definition (foresummit vs true summit), and 2025 season performance. Recent history matters more on Manaslu than on most 8000ers.
Furtenbach Adventures
Austrian-led operator known for systems-driven, data-heavy expeditions. Lukas Furtenbach was vocal after the 2022 avalanche about the lack of avalanche risk management on the mountain — and Furtenbach Adventures was one of the first to withdraw teams that year. Modern, technology-forward approach including pre-acclimatization, hyperbaric tents, and rigorous snow assessment. Higher-priced tier. furtenbachadventures.com
Seven Summit Treks
Kathmandu-based operator with the largest Manaslu operational footprint each autumn. Coordinates rope-fixing and Sherpa logistics for the broader climbing community.

Frequently Asked Questions
The Nepal climbing permit alone is $3,000 in autumn (most popular season) post September 2025 fees. A guided commercial expedition typically costs $14,000–$45,000 depending on operator, oxygen strategy, and support level. Budget operators (Nepali-led, basic logistics) run $14K–18K. Mid-tier expeditions run $22K–32K. Premium operators like Furtenbach Adventures or Madison Mountaineering run $35K–45K with high Sherpa ratios and modern weather forecasting.
No. On 9 May 1956, Toshio Imanishi and Gyalzen Norbu Sherpa reached the foresummit, which was treated as the summit of Manaslu for decades. The true summit was not reached until 1976 by a joint Iranian-Japanese expedition. In 2021 Mingma G’s Imagine Nepal team reached the true summit, with team member Jackson Grove’s drone imagery clearly showing the height disparity between the two points. In autumn 2022, Elite Exped’s Sherpa team became the first to fix ropes to the true summit, opening it to commercial teams. The Himalayan Database now requires climbers to reach the ridge point to count as a true summit ascent.
Autumn (September–October) is the dominant Manaslu season — approximately 568 of 775 historical expeditions through end of 2023 occurred in autumn. The 2025 season had a strong summit cycle starting 20 September after the rope-fixing team summited. Spring (April–May) is possible but less common; outfitters typically concentrate spring resources on Everest, Annapurna, Dhaulagiri, and Makalu. Most years, autumn offers better infrastructure, more shared support, and stronger weather windows on Manaslu.
Manaslu is statistically one of the safer 8000ers. Per Himalayan Database data through 2022, Manaslu has approximately 2,172 summits and 88 deaths for a 1.49% fatality rate — 7th safest of the 8 Tibet/Nepal 8000ers, with only Cho Oyu safer (0.59%). However, Manaslu has had two major avalanche tragedies that skew the picture: 11 dead in 2012 (serac release above Camp 3) and 2 dead in 2022 including American ski mountaineer Hilaree Nelson. Manaslu rewards operators with strong snow assessment protocols; in heavy-snow years the avalanche risk on the C2–C3 section is real.
4–7 weeks total. The trek from Soti Khola or Arughat to base camp takes 5–8 days; many 2025 expeditions used helicopter fly-in to Samagaon, cutting the approach to 1–2 days. Acclimatization rotations and weather waits add 2–4 weeks at base camp. Summit pushes typically happen in mid-to-late September or early October. Descent and trek out takes 4–5 days (or 1 day with helicopter exit).
Manaslu is the most “beginner-friendly” 8000er in the sense that the technical climbing is lower than K2 or Kangchenjunga and the commercial infrastructure is strong in autumn. But it is not a beginner mountain. Most operators require demonstrated experience on a 6,000m or 7,000m peak, plus glacier travel, fixed-line ascending, and crampon/ice-axe proficiency. As of January 2025, Nepal increasingly requires climbers attempting peaks above 8,000m to have summited a 7,000m peak in Nepal first. The “easy 8000er” reputation is also one of the reasons Manaslu has historical deaths from underprepared climbers.
Manaslu is in central Nepal in the Mansiri Himal (part of the Gorkha District), approximately 64 km east of the Annapurna massif. Coordinates: 28.5497°N, 84.5597°E. The trekking approach typically starts from Soti Khola or Arughat. The helicopter fly-in option to Samagaon Heliport has become increasingly popular for commercial expeditions in 2024–2025.
Yes. On 4 May 1974, Naoko Nakaseko, Masako Uchida, Mieko Mori, and Jambu Sherpa — a Japanese women’s expedition — completed the first ascent of Manaslu by women and the first ascent of any 8000-meter peak by a woman in mountaineering history. This was a watershed moment for women in Himalayan climbing.
The name comes from the Sanskrit word manasa, meaning “intellect” or “soul.” The mountain is also called Kutang in the local Nepali tongue, after a region of the Tibetan-Buddhist communities that surround it.
Manaslu Map & Live Weather
Manaslu’s summit coordinates: 28°33’00″N 84°33’35″E (28.5497°N, 84.5597°E). The map below shows the summit and the surrounding Mansiri Himal — Manaslu sits ~64km east of the Annapurna massif, with the trekking approach following the Budhi Gandaki river valley from Soti Khola in the south.
