Cho Oyu Death Rate: why the safest 8000er still is not safe
Cho Oyu is the least dangerous of the world’s fourteen 8,000-meter peaks, with a death rate around 1.4 percent, and it is the mountain most climbers choose for their first 8,000er. But safest is not the same as safe. Roughly one climber in seventy who summits does not survive the mountain, a rate far higher than any Alpine peak. Here is what that number really means, why Cho Oyu earns its reputation as the most accessible 8,000er, and why the easiest still kills.
The safest 8,000er, and still one in seventy.
Cho Oyu’s death rate is around 1.35 to 1.4 percent, the lowest of the fourteen 8,000ers, with roughly 50 deaths against 3,680-plus summits. That is comparable to Everest’s roughly 1 percent and a world away from the deadly giants like Annapurna and K2. It earns the title through a largely non-technical standard route and strong commercial support. But roughly one death for every seventy summits is still far more dangerous than any Alpine peak per climber, and the “easiest 8,000er” label is exactly what leads climbers to underestimate it.
The death rate
The lowest of the fourteen, but still an order of magnitude above the Alps.
Cho Oyu, at 8,188 m (26,864 ft), is the sixth-highest mountain in the world, standing on the Nepal-Tibet border roughly 30 km west of Everest. Its name means Turquoise Goddess. Among serious mountaineers it is best known for one statistic: at roughly 1.35 to 1.4 percent, its death rate is the lowest of any 8,000-meter peak, some 50 deaths against more than 3,680 successful ascents. That makes it the safest of the fourteen and puts it close to Everest’s roughly 1 percent. Both sit far below the deadly 8,000ers, where the rate climbs into the teens and twenties. The honest way to read Cho Oyu’s number is therefore in two directions at once: reassuringly low for an 8,000er, and still far more dangerous per climber than the Matterhorn or Mont Blanc.
Why it is the safest
A gentle standard route, short summit day, and strong support stack the odds in the climber’s favour.
Cho Oyu’s low rate is no accident. Its standard Northwest Ridge route, climbed from the Tibet side, is largely non-technical, following gently angled glacier and snow terrain rather than the sustained steep climbing of K2 or the avalanche-swept faces of Annapurna and Nanga Parbat. The summit day is comparatively short and less committing, fixed ropes are in place on the harder sections, and a strong commercial infrastructure supports most expeditions. Objective hazard, the rockfall, serac, and avalanche danger that drives the deadliest peaks, is lower here than almost anywhere else in the 8,000-meter world. Lower technical difficulty and lower objective hazard together produce the safest big peak in the Himalaya, which is why Cho Oyu is the second most-climbed 8,000er after Everest and the standard choice for a first one.
Why climbers still die
The killer here is altitude, and the trap is the word “easy.”
Nothing about 8,188 m is easy. The leading causes of death on Cho Oyu are not falls or technical failure but altitude itself: high-altitude cerebral and pulmonary edema, cold, exhaustion, and sudden weather, with occasional avalanche or serac hazard on the route. The danger is amplified by perception. Because Cho Oyu is marketed and remembered as the easiest 8,000er, some climbers arrive with too little high-altitude experience, or press on toward the summit when the sensible choice is to turn around. Above 8,000 meters, in the death zone, that single misjudgment can be fatal on the gentlest terrain. The mountain’s low death rate reflects its route, not any softness in the altitude.
The label is true only in relative terms, and it quietly encourages underestimation. Cho Oyu still demands full 8,000-meter respect: proper acclimatization, high-altitude fitness, a hard turnaround discipline, and the experience to read your own body in the death zone. Treated as a genuine 8,000er it is the safest of the fourteen. Treated as a walk-up, it kills.
History & access
A landmark lightweight first ascent, and a standard route that depends on Tibet-side access.
How it compares
Cho Oyu anchors the safe end of the 8,000er spectrum.
| Peak | Approx. death rate | Risk profile |
|---|---|---|
| Cho Oyu | ~1.4% | The least dangerous 8,000er |
| Everest | ~1% | Low rate, huge absolute toll |
| Nanga Parbat | ~20% | Avalanche, technical scale |
| K2 | ~23% | Sustained technical, the Bottleneck |
| Annapurna I | ~13-32% | Serac and avalanche exposure |
The spread among the 8,000ers is enormous, and Cho Oyu sits at the safe end with Everest while the deadly peaks run ten to twenty times higher. That range is the whole point of comparing death rates: not all 8,000ers are remotely alike. For the full picture, see our death rates by mountain hub and the 8,000ers ranked by difficulty, and for the other end of the scale, the Nanga Parbat death rate.

Cho Oyu death rate FAQ
The questions people ask most.
What is the death rate on Cho Oyu?
Around 1.35 to 1.4 percent, the lowest of the fourteen 8,000ers, about 50 deaths against more than 3,680 summits. That is comparable to Everest’s roughly 1 percent and far below Annapurna and K2. Still, one death per seventy summits is far more dangerous than any Alpine peak per climber.
Is Cho Oyu the easiest 8000er?
It is the most accessible: a largely non-technical standard route from Tibet, fixed ropes, strong support, and a short summit day. But easiest is relative, and it is still a full 8,000-meter Himalayan peak that the label leads some to underestimate.
Why is it safer than other 8000ers?
Its normal route avoids the sustained technical climbing and severe objective hazards of K2, Annapurna, and Nanga Parbat. Gentle terrain, a shorter summit day, and strong infrastructure together give it the lowest death rate of the group.
Is it a good first 8000er?
Yes, it is the classic first 8,000er and a common Everest stepping stone, offering real 8,000-meter experience at the lowest death rate of the fourteen. It still demands acclimatization and respect, and Tibet-side access has been intermittently restricted.
What kills climbers on Cho Oyu?
Mostly altitude: HACE, HAPE, cold, exhaustion, and sudden weather, with occasional avalanche or serac hazard. Because the route is seen as easy, some climbers arrive underprepared or push on when they should turn back.
Methodology, sources & editorial standards
How this analysis was built, and the limits of what it can promise.
📋 Editorial standards & source verification
This Cho Oyu death-rate analysis cross-checks figures against the Himalayan Database and published 8,000er fatality studies. The roughly 1.4 percent rate, and the figure of about 50 deaths against 3,680-plus summits, are the most widely cited estimates and place Cho Oyu as the least dangerous of the fourteen. All figures are approximate and shift with each season and each source’s counting method.
The mountain’s safety reputation rests on its non-technical Tibet-side route. Its low rate reflects that route and its strong support, not any softness in the altitude, and it does not transfer to harder alternative lines or to underprepared climbers.
◆ Research-based, honestly framed
The Global Summit Guide editorial team has not climbed Cho Oyu, and no one on the team has summited an 8,000-meter peak. This analysis synthesizes authoritative fatality records and primary mountaineering reporting rather than first-hand experience of the mountain. The team’s own high-altitude experience includes Kilimanjaro (5,895 m, summited by Dawson Ludlow), Pico de Orizaba (5,636 m), Iztaccihuatl, Rainier-class glaciated volcanoes, and Utah peaks, which informs our understanding of commercial high-altitude operations. Death-rate statistics are objective and verifiable across sources, which is what makes a research-based synthesis useful here.
