8000ers Ranked by Difficulty: From Cho Oyu (1.4%) to Annapurna (32%)
“Climbing the eight-thousanders” sounds like one endeavour. It isn’t. The fatality-rate gap between the safest and most dangerous of the 14 peaks is roughly 19-fold. This guide ranks all fourteen 8,000 m peaks from easiest to hardest using a four-signal composite — fatality rate, technical difficulty, commercial accessibility, and weather-window reliability — and shows the right progression toward the most dangerous mountains on Earth.
Quick Answers: The Superlatives
The questions climbers ask most — answered up front, then explained in full below.
In one line: Cho Oyu is the easiest and safest; Annapurna I is the deadliest; K2 is the most technical; the two hardest overall are K2 and Annapurna. Most of the 14 are harder than Everest’s standard route — the exceptions being Cho Oyu, Gasherbrum II, Lhotse, and often Broad Peak and Shishapangma.

What Counts as an Eight-Thousander
The 14 eight-thousanders are the mountains with summits above 8,000 m (26,247 ft), recognised by the UIAA. They sit entirely in the Himalaya and Karakoram, across Nepal, Tibet, Pakistan, India, and China, and span from Shishapangma (8,027 m) to Mount Everest (8,848.86 m). They are the only places on Earth where climbers operate for extended periods in the “death zone,” where the body can no longer acclimatise.

Cho Oyu at one end is a commercially guided near-walk-up where careful first-time 8,000 m climbers can summit safely; Annapurna I at the other has historically killed roughly one climber for every three who reach the top. Elevation order tells you almost nothing about difficulty — which is why this ranking exists.
The 4-Signal Composite Method
No single number captures 8,000 m difficulty. Fatality rate alone misleads — Annapurna’s historical 32% reflects a different era than today’s ~13%, and K2’s technical demand outstrips peaks with similar nominal rates. So this ranking scores each peak on four signals, then combines them into a tier:
| 1 · Fatality rate | Cumulative deaths ÷ cumulative summits (Himalayan Database / 8000ers.com), weighing the modern era alongside the all-time figure. |
| 2 · Technical difficulty | The demands of the standard commercial route — steepness, exposure, fixed-rope dependence, rock and ice sections, route-finding. |
| 3 · Commercial accessibility | Whether reliable guided support exists — fixed-rope teams, base-camp logistics, Sherpa/high-altitude porter support, operator competition. |
| 4 · Weather-window reliability | How predictable and long the typical summit window is. Spring Nepal peaks have defined April-May windows; Karakoram windows are shorter and less reliable. |
The composite answers the practical question climbers actually face: given my experience and the support available, which peaks should I attempt, and in what order? The resulting tiers line up closely with operator-industry consensus.
The Master Ranking — All 14 Peaks
Ordered easiest (1) to hardest (14) by composite difficulty, grouped into four tiers. Note how little elevation predicts difficulty — Cho Oyu (8,188 m) is far easier than Annapurna (8,091 m).
| # | Peak | Elevation | Tier | Fatality | Why | Location |
|---|---|---|---|---|---|---|
| 1 | Cho Oyu | 8,188 m | 1 | ~1.4% | Walk-up + one ice band | Nepal-Tibet |
| 2 | Gasherbrum II | 8,035 m | 1 | ~2.4% | Glacier + couloir | Pakistan-China |
| 3 | Manaslu | 8,163 m | 1 | ~6% | Accessible but avalanche-prone | Nepal |
| 4 | Mount Everest | 8,848.86 m | 2 | ~3% | Altitude + crowding, not technique | Nepal-Tibet |
| 5 | Lhotse | 8,516 m | 2 | ~3% | Technical couloir above the Col | Nepal-Tibet |
| 6 | Broad Peak | 8,051 m | 2 | ~5% | Long ridge + false summit | Pakistan-China |
| 7 | Shishapangma | 8,027 m | 2 | ~6% | Avalanche ridge, Tibet-only access | Tibet (China) |
| 8 | Gasherbrum I | 8,080 m | 3 | ~9% | Japanese Couloir, sustained technical | Pakistan-China |
| 9 | Makalu | 8,485 m | 3 | ~9% | Technical summit pyramid | Nepal-Tibet |
| 10 | Dhaulagiri I | 8,167 m | 3 | ~13% | Remote, avalanche + weather | Nepal |
| 11 | Kangchenjunga | 8,586 m | 4 | ~15% | Remote, technical, little support | Nepal-India |
| 12 | Nanga Parbat | 8,126 m | 4 | ~21% | “Killer Mountain,” extreme weather | Pakistan |
| 13 | K2 | 8,611 m | 4 | ~22% | Most technical, “Savage Mountain” | Pakistan-China |
| 14 | Annapurna I | 8,091 m | 4 | ~32% / 13%* | Avalanche-dominated, most dangerous | Nepal |
* Annapurna I: ~32% all-time historical, ~13% modern era (post-2000) — better forecasting, fixed ropes, and commercial support have roughly halved the rate.
How to Read the Fatality Numbers
Fatality rates are the headline figure on any 8000er ranking, but they’re slipperier than they look — and understanding why is the difference between a useful number and a misleading one.
Historical vs modern. The biggest trap is era. Annapurna’s infamous ~32% is an all-time figure stretching back to 1950, before modern forecasting, fixed ropes, and commercial logistics; its modern-era rate is closer to ~13%. K2, Nanga Parbat, and the harder Karakoram peaks have all seen similar improvements. A 1970s death rate and a 2020s death rate describe almost different mountains, so this ranking weighs both rather than quoting the scariest number.
The denominator problem. “Deaths per summit” and “deaths per attempt” produce very different figures, and sources don’t always agree on which they’re using or how they count disputed ascents and descent deaths. Low-traffic peaks like Annapurna or Kangchenjunga also have small sample sizes, so a single bad season swings their percentage far more than it would on heavily climbed Everest.
Rate vs raw toll. Per-climber rate and total deaths are different questions. Everest and Mont Blanc have killed far more people in absolute terms simply because so many attempt them, even though their per-climber risk is comparatively low — see our fatality-rate ranking and death rates by mountain for both views.
Oxygen and style change everything. The figures here assume the standard commercially supported route with supplemental oxygen. Climbing without oxygen, in winter, or by a harder line raises the real difficulty of any of these peaks by a full tier or more — Everest without oxygen is a far more dangerous proposition than the ~3% suggests.
Tier 1 — The Accessible 8000ers
1.Cho Oyu — the safest commercial 8000er
The standard first eight-thousander. The Tibetan Northwest Ridge is technically straightforward — essentially a walk-up with one steep ice band on fixed rope — and established operators can support careful first-timers through the whole expedition. Tibet permits have periodically been restricted, so verify current access before booking.
2.Gasherbrum II — the safer Karakoram 8000er
The safer entry to Karakoram climbing, with risk comparable to Cho Oyu. The Southwest Ridge mixes glacier travel, fixed-line sections, and a final couloir. Karakoram weather windows are shorter and less reliable than Nepal’s, so many climbers use GII to build Karakoram experience before Broad Peak, Gasherbrum I, or K2.
3.Manaslu — accessible but avalanche-prone
Sits alongside Cho Oyu as an accessible commercial 8000er, but with meaningfully higher avalanche risk — the 2012 avalanche killed 11 in a single event. The Northeast Face is well supported with fixed ropes and Sherpa teams. Autumn (Sept–Oct) is often preferred over spring for reduced avalanche exposure low on the mountain.
Tier 2 — The Mainstream 8000ers
4.Mount Everest — maximum altitude, maximum infrastructure
Its placement reflects extreme altitude paired with the most developed infrastructure ever built around an 8000er. Prepared climbers with premium operators see 70–85% summit success — higher than the bare height suggests. The real risks are altitude exposure, the Khumbu Icefall, and crowding-driven summit pressure. The huge cost spread reflects genuine differences in safety margin between operator tiers.
5.Lhotse — technical couloir above the shared Everest route
Shares roughly 80% of Everest’s route to the South Col, then diverges into the sustained 40–60° mixed ice of the Lhotse Couloir — meaningfully more technical than Everest’s summit ridge, which is why it’s rated separately. The Everest–Lhotse combo is the best-value double-peak, adding only $5–10K over Everest.
6.Broad Peak — Karakoram with commercial support
One of the more accessible Karakoram 8000ers, operated out of Skardu. The Northwest Spur involves glacier travel and a long summit ridge with a notorious false summit — climbers who don’t recognise it consistently turn around short of the true top. Often climbed before Gasherbrum I or K2.
7.Shishapangma — the lowest 8000er, Tibet-only
The only eight-thousander entirely within Tibet, and the last to be first-climbed (1964). The North Face is technically moderate, but access depends on China’s permit policy, which has closed entirely at times. The avalanche-prone summit ridge remains a real hazard — the 2023 avalanche killed two American climbers — making it the most logistically complex Tier 2 peak despite its low height.
Tier 3 — The Serious 8000ers
8.Gasherbrum I (Hidden Peak) — technical Karakoram
Hidden Peak — invisible from any inhabited area — sits beside its easier sibling GII, but the standard Japanese Couloir on the Northwest Face is sustained technical ice and snow, clearly harder than GII. The technical step-up plus short Karakoram windows drives the higher fatality rate. Most climbers tackle it after GII, transferring that Karakoram experience to GI’s steeper terrain.
9.Makalu — the technical summit pyramid
The world’s fifth-highest peak is a striking four-sided pyramid with a genuinely technical finish — the summit block demands rock climbing in crampons at extreme altitude, a different challenge from the snow-plodding of the easier 8000ers. First climbed in 1955 by Lionel Terray and Jean Couzy’s French team. Strong prior 8,000 m experience is essential.
10.Dhaulagiri I — remote, avalanche-exposed
The seventh-highest peak sees far fewer expeditions than commercial 8000ers — typically tens, not hundreds, of attempts per season — which means less fixed infrastructure and thinner rescue cover. Serious avalanche risk and notoriously variable weather push the fatality rate into the low teens. Climbers here are usually building remote-expedition discipline before Annapurna, K2, or the Karakoram.
Tier 4 — The Most Dangerous 8000ers
11.Kangchenjunga — remote and unforgiving
The third-highest mountain on Earth is technical on every standard route, remote, and lightly supported — a combination that has killed roughly one climber in seven. By tradition, climbers stop a few metres short of the true summit out of respect for the deity, a custom most expeditions still honour. First climbed in 1955 by Joe Brown and George Band.
12.Nanga Parbat — the “Killer Mountain”
The western anchor of the Himalaya earned its grim nickname through a long, lethal history before its first ascent — Hermann Buhl’s 1953 solo summit push, made alone and without oxygen, remains one of mountaineering’s most extraordinary feats. Immense faces, extreme weather, and serious objective hazard keep the fatality rate above 20%.
13.K2 — the “Savage Mountain,” most technical
The second-highest peak is the most technically demanding of the 14. Unlike mountains where the danger sits in one place, K2’s standard Abruzzi Spur demands expert climbing along its entire length, capped by the Bottleneck — a couloir beneath an unstable serac at ~8,200 m where the 2008 disaster killed 11 in a day. Even strong climbers with prior 8,000 m ascents face roughly one-in-four odds.
14.Annapurna I — the most dangerous of all
The first eight-thousander ever climbed (Herzog and Lachenal, 1950) has remained the deadliest ever since. Its danger is structural: avalanche-prone slopes and serac fall on the standard routes mean climbers can be in the wrong place at the wrong moment through no failure of skill or judgement. The ~32% all-time rate has fallen to roughly 13% in the modern era with better forecasting and fixed-rope support, but it remains the mountain with the highest fatality rate of the 14.

Which 8000er Should You Climb First?
For most climbers with solid 6,000–7,000 m experience, the right first eight-thousander is Cho Oyu, with Manaslu as the main alternative and Everest viable with premium operator support. The point isn’t the single peak — it’s the progression. Climbers don’t start at 8,000 m; they accumulate years through peaks like Kilimanjaro, Aconcagua, and Rainier or Denali, then a first 8000er, before attempting Tier 3 or Tier 4 objectives.
Climbers who skip the build-up and attempt a Tier 3 or Tier 4 peak as their first 8000er face dramatically higher fatality risk than those who built the foundation systematically. Weight commercial accessibility heavily for a first 8,000 m attempt, and technical difficulty heavily once you reach Tier 3 and 4.

How This Differs From Our Pillar Guide
Global Summit Guide covers the eight-thousanders across two complementary pages, and it’s worth knowing which to use:
- This page ranks the 14 by difficulty — the composite tiers, the easiest-to-hardest order, and the superlatives (safest, deadliest, most technical). Use it to decide which peaks to attempt and in what order.
- Our 14 Eight-Thousanders pillar guide profiles every peak — full history, routes, records, and planning detail for each of the fourteen. Use it to go deep on a specific mountain.
Together they answer the two different questions climbers ask: which 8000er, and how hard? (here) versus tell me everything about this peak (the pillar).

Eight-Thousanders FAQ
What is the easiest 8000m peak to climb?
Cho Oyu (8,188 m) is the easiest and safest, with a fatality rate around 1.4%. Its Tibetan Northwest Ridge is essentially a guided walk-up with one steep ice band, well supported by operators – which is why it’s the usual first 8,000 m peak. Gasherbrum II and Manaslu are next.
What is the hardest 8000m peak to climb?
The two hardest are K2 and Annapurna I. K2 (8,611 m) is the most technically demanding, with sustained difficulty and the deadly Bottleneck serac; Annapurna I (8,091 m) is the most dangerous by fatality rate, historically killing about one climber for every three who summit.
What is the safest 8000m peak?
Cho Oyu, at roughly 1.4% – the lowest fatality rate of the 14. Its non-technical route, fixed ropes, and strong commercial support make it the safest, though no 8,000 m peak is truly safe.
What is the most dangerous (deadliest) 8000m peak?
Annapurna I, with the highest fatality rate of the 14 – around 32% historically and about 13% in the modern era. Its danger comes from avalanche-prone slopes that climbing skill cannot fully avoid.
What is the most technical 8000m peak?
K2, the ‘Savage Mountain.’ Its standard Abruzzi Spur demands expert technical climbing along its entire length, capped by the Bottleneck couloir beneath an unstable serac at about 8,200 m.
Which 8000m peaks are harder than Everest?
By their standard routes, most: K2, Annapurna I, Kangchenjunga, Nanga Parbat, Makalu, Dhaulagiri, and Gasherbrum I are all harder or more dangerous than Everest’s South Col route. Cho Oyu, Gasherbrum II, Lhotse, and often Broad Peak and Shishapangma are easier – Everest’s altitude is offset by unmatched infrastructure.
Which is the least-summited 8000m peak?
Annapurna I and Kangchenjunga are among the least-summited, with far fewer ascents than commercial peaks like Everest, Cho Oyu, or Manaslu. Shishapangma also sees relatively few attempts because Tibet permits periodically close.
How many 8000m peaks are there?
There are 14 – the only mountains on Earth above 8,000 m (26,247 ft), recognised by the UIAA. All lie in the Himalaya and Karakoram across Nepal, Tibet, Pakistan, India, and China, from Shishapangma (8,027 m) to Everest (8,848.86 m).
What are all 14 eight-thousanders?
By height: Everest, K2, Kangchenjunga, Lhotse, Makalu, Cho Oyu, Dhaulagiri I, Manaslu, Nanga Parbat, Annapurna I, Gasherbrum I, Broad Peak, Gasherbrum II, and Shishapangma.
Which 8000m peak should you climb first?
For most climbers with solid 6,000-7,000 m experience, Cho Oyu is the right first eight-thousander, with Manaslu as the main alternative and Everest viable with premium support. Building the progression matters far more than any single peak’s difficulty.
