Annapurna Summit Success Rate: the deadliest 8,000er per attempt
Annapurna I (8,091 m / 26,545 ft) was the first 8,000 m peak ever climbed – and the 75 years since have confirmed why it was the last of the major eight-thousanders to see a second ascent. Its 16% overall success rate is the lowest of any regularly-climbed 8,000 m peak, lower even than K2, and its roughly 1-in-4 fatality rate is the highest in the Himalaya. The cause is a single, uncomfortable fact: the North Face’s avalanche hazard cannot be eliminated by skill, timing, or experience.
No other 8,000 m mountain kills a higher proportion of the climbers who attempt it.
Annapurna’s defining feature isn’t technical difficulty or altitude – it’s objective, uncontrollable avalanche hazard distributed across the entire North Face. That’s why even the most experienced climbers here show relatively low success rates, and why the gap between experience levels is smaller than on any other 8,000 m peak: the hazard is the equalizer.
The honest planning takeaway is unusual. On most peaks, preparation buys you a dramatically better outcome. On Annapurna, preparation lowers your risk at the margin but cannot remove the avalanche floor – every serious team accepts true uncontrollable risk as a condition of the attempt.

Success rate by month
A pre-monsoon May window – but shorter and more avalanche-loaded than Everest’s, because Annapurna meets the monsoon first.
Annapurna’s summit window is pre-monsoon May, shared with Everest and most central Himalayan peaks. But its position at the western edge of the massif means it intercepts monsoon systems before they reach Everest – the window is shorter, the avalanche loading from pre-monsoon snowfall is higher, and timing errors carry more severe consequences. The first three weeks of May produce the vast majority of summits. The critical signal in the data: avalanche loading increases sharply after about May 15, so teams positioned and acclimatized to attempt before mid-May consistently show better outcomes and lower exposure than those pushing into the final weeks of the season. Post-monsoon October sees fewer than 15 attempts a year – the monsoon loads enormous snow onto the North Face, keeping spring the strongly preferred window.
Success rate by route
The North Face is the standard modern line – and its rate is the lowest standard-route rate of any 8,000er here.
North Face
Modern standard route, three high camps, fixed ropes set cooperatively each season. Serious avalanche exposure throughout – unavoidable objective hazard. Most commercial support concentrated here.
Northwest Face / Dutch Rib
Different avalanche-exposure profile, less traffic, requires strong mixed-climbing skills. Small sample size adds uncertainty to the rate.
South Face
One of the great achievements in Himalayan mountaineering – extreme mixed climbing throughout, elite teams only, tiny attempt volume. Among the most demanding lines ever attempted at 8,000 m.
Guided vs independent
A 14-point gap – narrower than on peaks where rope-fixing is the main differentiator, because no team can eliminate the avalanche hazard.
| Factor | Guided / Sherpa-supported | Independent |
|---|---|---|
| Summit success | ~22% | ~8% |
| Primary advantage | Weather-window judgment – not technical guidance | Self-organized; relies on shared North Face ropes |
| Avalanche knowledge | Sherpa teams carry route-specific pattern knowledge | Avalanche hazard is equal regardless of team |
| Emergency response | Coordinated evacuation reduces response time from Camp 2 | Climber-arranged |
| Typical all-in cost | $20,000-$45,000 | $14,000-$28,000 |
On Annapurna the guided advantage reflects weather judgment and acclimatization-protocol enforcement more than technical guidance – because the avalanche hazard creates an irreducible objective risk that even the most experienced guided teams cannot eliminate.
Success rate by experience level
A distinctive shape: even the most experienced climbers show low rates, because objective hazard operates independently of skill.
| Prior experience | Success | Why |
|---|---|---|
| Fewer than 3 prior 8,000 m summits | 6% | Not an appropriate objective without extensive 8,000 m experience – the hazard adds to, rather than replaces, altitude risk |
| 3-5 prior 8,000 m summits (technical) | 16% | Solid preparation, but outcomes are still driven by which slope releases when |
| 5+ prior 8,000 m summits (demanding routes) | 24% | Better weather/timing judgment – but an irreducible risk floor no experience removes |
| Prior Annapurna attempt (route familiarity) | 36% | Strongest predictor; route-specific avalanche/timing knowledge is truly valuable |
The gap between experience levels is smaller here than on any other 8,000 m peak – objective hazard is the equalizer. The one factor that moves the needle most is a prior Annapurna attempt: return teams who survived a previous attempt carry irreplaceable experiential knowledge of the North Face’s particular avalanche patterns, timing, and weather behavior.
Most common turnaround reasons
On Annapurna, the boundary between “turnaround” and “fatality” is defined by avalanche events more than on any other mountain here.
Avalanche hazard – objective & uncontrollable
Persistent avalanche hazard from seracs and slope loading that timing, skill, and route choice cannot eliminate. Avalanche incidents have caused more Annapurna fatalities than all other causes combined; many turnarounds follow near-misses that reshape a team’s willingness to continue.
Weather – early monsoon & pre-monsoon storms
Annapurna intercepts monsoon weather before most central Himalayan peaks, and pre-monsoon snowfall after May 15 sharply increases avalanche loading. Teams that miss the early-May window often find conditions deteriorating faster than expected.
Extreme altitude illness above 7,000 m
HACE and HAPE are common above 7,000 m even in well-acclimatized teams; the technical North Face means more time at extreme altitude per attempt than on more direct routes.
Technical difficulty on the upper North Face
The serac-threatened sections above Camp 3 demand sustained mixed climbing at extreme altitude – more technical execution than many 8,000 m peaks at comparable altitude.
Team decision after an incident or near-miss
A sizable share of turnarounds follow witnessed avalanche incidents lower on the mountain – seeing the objective hazard materialize leads teams to correctly reassess.
Historical trend (1950-2025)
Modest improvement – but the fatality rate has not fallen proportionally.
Annapurna’s success rate has improved modestly from the pioneering era to the modern period, but remains the lowest of any regularly-climbed 8,000er. The main driver was the consolidation of attempts onto the North Face as the standard route around 1990, replacing the more lethal early approaches with a line whose hazard sections are at least better understood. The plateau since 2000 reflects the irreducible avalanche hazard that no amount of experience, equipment, or forecasting can eliminate. Crucially, the fatality rate has not improved in step with the success rate – Annapurna remains categorically more dangerous per attempt than any other peak in this database.
What these numbers mean for your planning
The four decisions most correlated with success – and survival – on Annapurna.
📅 Target early May
Arrive at base camp by mid-April for two full rotations. Avalanche loading rises sharply after May 15, so a May 1-15 summit window consistently shows better outcomes and lower exposure.
⚠ Accept the avalanche risk explicitly
The North Face hazard is objective and uncontrollable; no route, timing, or experience eliminates it. Every serious team discusses and accepts this as a condition of the attempt – honestly, before committing.
⛰ Complete 5+ prior 8,000 m summits
Annapurna is an advanced objective only. Prior experience on technically demanding peaks – ideally including serious avalanche terrain – is the minimum practical standard.
🌧 Use Annapurna-calibrated forecasting
The massif intercepts different systems than Everest; generic Himalayan forecasts underestimate how fast conditions deteriorate here. Meteorologists with Annapurna-specific experience give clearly better window guidance.

Annapurna I Climb Guide All Success RatesAnnapurna success rate FAQ
The questions climbers search most.
What is the Annapurna success rate?
~16% across all routes and the full 1950-2025 record – the lowest of any regularly-climbed 8,000er, lower even than K2. The modern North Face standard route in good seasons runs ~24%. The overall figure is held down by lethal early approaches, the extreme South Face, and irreducible avalanche hazard.
Why is Annapurna the deadliest 8,000er?
Its danger is objective and uncontrollable. North Face avalanche hazard from seracs and slope loading can’t be eliminated by timing, skill, or route choice, and it’s distributed across the whole face rather than confined to one section like K2’s Bottleneck. Avalanches cause more Annapurna deaths than all other causes combined.
What is the death rate?
Across the permitted record, roughly 1 in 4 climbers who attempt Annapurna I don’t survive – the highest fatality-to-attempt ratio of any 8,000er, alongside K2. The 1-in-16 rescue rate understates it, since many avalanche events leave no survivors. Maximum-limit evacuation insurance is essential.
When is the best time to climb?
The first three weeks of May. Annapurna meets the monsoon before Everest, so the window is short and avalanche loading rises sharply after ~May 15. Arrive at base camp by mid-April for two rotations. October sees fewer than 15 attempts a year.
How much experience do I need?
It’s an advanced 8,000 m objective. Climbers with fewer than three prior 8,000ers reach ~6%; 5+ prior summits ~24%; a prior Annapurna attempt is the strongest predictor at 36%. The practical minimum is 5+ prior 8,000ers, ideally including avalanche terrain.
How much does it cost?
Guided/Sherpa-supported ~$20,000-$45,000 all-in; independent ~$14,000-$28,000. A Nepal Mountaineering Association permit is required; independent teams still use the shared North Face ropes. The guided advantage is mainly weather judgment – the avalanche hazard is equal for everyone.

The one peak where preparation isn’t enough
On most mountains, doing everything right earns you a dramatically better outcome. On Annapurna, doing everything right lowers your risk at the margin but cannot remove the avalanche floor. If you climb it, climb it with clear eyes: target early May, bring deep 8,000 m experience, use Annapurna-calibrated forecasting, and accept the objective risk explicitly.
