The 14 Eight-Thousanders Ranked by Difficulty: From Cho Oyu (1.4%) to Annapurna (32%)

Cho Oyu is the standard first 8,000-meter peak for commercial climbers building toward Everest or other 8000ers. Generally, the Tibetan Northwest Ridge route is technically straightforward — essentially a walk-up with one steep ice band requiring fixed-rope climbing. Specifically, the established commercial guiding infrastructure means Nepali-led teams can support careful first-time 8,000-meter climbers through the entire expedition. Notably, Tibet access policies have periodically restricted Cho Oyu permits — climbers should verify current access before booking.

Manaslu sits alongside Cho Oyu as the accessible commercial 8000er, but with meaningfully higher avalanche risk that elevates the fatality rate. Generally, the Northeast Face route is well-supported by commercial operators with fixed-rope infrastructure and established Sherpa teams. Specifically, the 6% fatality rate reflects multiple historical avalanche disasters including the 2012 event that killed 11 climbers in a single avalanche. Notably, Manaslu’s autumn season (September-October) is often preferred over spring because of reduced avalanche exposure on the lower mountain.

Gasherbrum II is the safer commercial entry point to Karakoram 8,000-meter climbing, with a fatality rate comparable to Cho Oyu. Generally, the Southwest Ridge route involves glacier travel, fixed-line climbing on steeper sections, and a final couloir push to the summit. Specifically, Karakoram weather windows are shorter and less reliable than Nepal Himalaya windows, adding logistical complexity. Notably, GII is the first peak many climbers attempt as a Karakoram-experience builder before moving on to Broad Peak, the Gasherbrum I traverse, or eventually K2.

Everest’s tier placement reflects the unusual combination of extreme altitude (highest mountain on earth) with the most developed commercial climbing infrastructure ever built around an 8000er. Generally, prepared climbers using premium Western operators have summit success rates of 70-85% — meaningfully higher than the bare elevation would suggest. Specifically, Everest’s primary risks are altitude exposure (the summit push extends time above 8,000 meters), Khumbu Icefall objective hazard, and crowding-driven summit window pressure. Notably, the dramatic cost spread ($33K to $230K+) reflects real differences in safety margin between operator tiers.

Lhotse shares roughly 80% of its climbing route with Everest up to the South Col, then diverges into the technically demanding Lhotse Couloir for the summit push. Generally, the Couloir’s sustained 40-60 degree mixed ice and snow climbing is meaningfully more technical than Everest’s summit ridge. Specifically, this technical difference is the primary reason Lhotse is rated separately despite sharing route infrastructure. Notably, Lhotse offers the best value double-peak option via the Everest-Lhotse combo, which adds only $5,000-$10,000 over the Everest base cost.

Broad Peak is one of the more accessible Karakoram 8000ers with established commercial operator infrastructure operating from Pakistan’s Skardu region. Generally, the Northwest Spur route involves glacier travel and a long summit ridge, with the notorious false summit creating the classic Broad Peak summit-day decision point. Specifically, climbers who don’t recognize the false summit and turn around early consistently fail to summit the true peak. Notably, Broad Peak is often climbed as a Karakoram experience builder before Gasherbrum I or K2 attempts.

Shishapangma is the only 8000er located entirely within Tibet (China), and the last 8,000-meter peak to receive a first ascent in 1964. Generally, the North Face route is technically moderate but commercial access depends entirely on China’s Tibet permit policies, which have periodically closed entirely during politically sensitive periods. Specifically, the 6% fatality rate reflects an avalanche-prone summit ridge — the 2023 avalanche that killed two American climbers including Anna Gutu and Gina Marie Rzucidlo highlighted the persistent objective risk. Notably, Tibet access uncertainty makes Shishapangma the most logistically complex of the Tier 2 peaks despite its lowest elevation.

Gasherbrum I — also called Hidden Peak because it isn’t visible from any inhabited area — sits in the Karakoram alongside its more accessible sibling GII. Generally, the standard route via the Japanese Couloir on the Northwest Face involves sustained technical ice and snow climbing meaningfully more demanding than GII. Specifically, the technical step-up combined with shorter Karakoram weather windows produces the higher fatality rate. Notably, GI is often climbed after GII as the natural progression — climbers who summit GII first develop the Karakoram experience that transfers to GI’s more demanding terrain.

Makalu’s distinctive pyramid summit is the most genuinely technical of the commercially-climbed 8000ers. Generally, the Southeast Ridge route involves sustained rock climbing in mountaineering boots and crampons at extreme altitude — a combination that exposes climbers without prior technical rock background. Specifically, premium Western operators on Makalu increasingly require Cho Oyu or another prior 8,000-meter summit, and rock climbing experience in mountaineering boots is the de facto unwritten prerequisite. Notably, Makalu’s West Pillar route (Piolet d’Or winning ascents) is one of the hardest 8,000-meter climbs ever completed and remains an elite expedition objective.

Dhaulagiri’s tier placement is the most contested in the rankings — some operators rate it as a Tier 2 peak, while the 13% fatality rate places it firmly in serious 8000er territory. Generally, the Northeast Ridge standard route involves avalanche-prone slopes, weather variability that often forces summit bid abandonment, and less commercial infrastructure than Tier 2 Nepal peaks. Specifically, Dhaulagiri’s geographic isolation west of the main Annapurna massif limits operator competition and Sherpa team consistency. Notably, climbers building toward K2 or Annapurna I often use Dhaulagiri as the technical and weather-management test before committing to Tier 4 objectives.

Kangchenjunga, the third-highest mountain on earth, sits on the Nepal-India border with restricted access and limited commercial infrastructure compared to the Khumbu region 8000ers. Generally, the Southwest Face route via the Yalung approach requires technical fixed-line climbing, long summit days, and self-sufficiency that the Khumbu peaks don’t demand. Specifically, the religious tradition of leaving the actual summit untrodden (climbers traditionally stop a few meters short out of respect for the local Sikkimese beliefs) adds a unique cultural dimension. Notably, Kangchenjunga’s remote character makes rescue and evacuation meaningfully harder than on Everest or Lhotse — a factor reflected in the elevated fatality rate.

Nanga Parbat earned the “Killer Mountain” designation during early German expeditions that claimed numerous lives before Hermann Buhl’s solo first ascent in 1953. Generally, the standard Kinshofer route on the Diamir Face involves technical mixed climbing with sustained avalanche and rockfall hazard. Specifically, Nanga Parbat’s location at the far western end of the Himalaya creates uniquely volatile weather patterns — summer monsoon influence and high storm frequency create shorter, less predictable summit windows than Karakoram or Khumbu peaks. Notably, the 2013 Nanga Parbat base camp attack that killed 11 climbers added political risk to the technical risk, though security has since stabilized.

K2 is widely considered the most technically demanding of the 14 eight-thousanders — the “Savage Mountain” nickname captures its sustained technical difficulty across the entire route. Generally, the standard Abruzzi Spur involves the infamous Bottleneck section below the summit where climbers traverse beneath an unstable serac that has caused multiple avalanche disasters. Specifically, K2 demands more technical rock and ice competence than any other commercial 8000er, with sustained sections of mixed terrain that reward climbers with established alpine climbing background. Notably, recent commercial K2 seasons have seen meaningfully improved summit success rates due to better fixed-rope infrastructure and weather forecasting — but the underlying technical character and objective hazard remain unchanged.

Annapurna I — the first 8,000-meter peak ever climbed in 1950 — remains statistically the most dangerous of the 14 eight-thousanders. Generally, the 32% historical fatality rate reflects the early era of Himalayan climbing combined with Annapurna’s persistent avalanche risk and weather variability. Specifically, the modern era fatality rate has improved dramatically to approximately 13% with better weather forecasting, fixed-rope infrastructure, and commercial expedition support — but Annapurna remains the deadliest 8000er by any measure. Notably, the standard North Face route crosses sustained avalanche-prone slopes that no amount of operator expertise can eliminate as an objective hazard.
