Which 8,000-Metre Peak Actually Kills the Most Climbers? The Real Death-Rate Numbers, Explained
This week's avalanche on Pakistan's Broad Peak has renewed the Karakoram's reputation as the world's deadliest climbing ground — but seven decades of summit-and-death records show the real picture is more specific, and more surprising, than Karakoram versus Everest.
Pakistan's Broad Peak has just claimed at least four more lives in an avalanche near Camp 3, reviving a familiar shorthand among climbers and headline writers alike: the Karakoram is the world's deadliest mountain range, full stop. The real numbers, tracked peak by peak across seven decades of Himalayan and Karakoram mountaineering, tell a more specific and more useful story.
Key facts
- Of the 14 peaks above 8,000m, four sit in the Karakoram: K2, Broad Peak, Gasherbrum I and Gasherbrum II
- K2’s cumulative fatality ratio is around 20–25% across all-time attempts, though record commercial seasons in 2022–2023 have pulled the running figure closer to ~13%, according to mountaineering-statistics trackers
- Gasherbrum II, the most-climbed Karakoram 8,000er, has one of the lowest fatality rates of any peak on the list — about 2%
- The single deadliest 8,000er by percentage isn't in the Karakoram at all — it's Annapurna I, in Nepal's own Himalaya
The Karakoram's fearsome reputation is earned, but it is concentrated in specific terrain rather than spread evenly across the range. K2's notoriety centres on the Bottleneck, a narrow, ice-choked couloir at roughly 8,300m directly beneath a hanging serac wall; a collapse there in August 2008 killed 11 climbers in a single day, the deadliest incident in the mountain's history. Broad Peak's risk is different again: an exposed, multi-hour traverse near the summit ridge where climbers move for long stretches with no fixed protection, in a zone with almost no permanent rescue infrastructure. Gasherbrum II, by contrast, follows a comparatively gentle glacier route and has become the easy Karakoram 8,000er precisely because it avoids that kind of terrain trap.
| Peak | Range | First ascent | Est. fatality rate |
|---|---|---|---|
| Annapurna I | Nepal Himalaya | 1950 | ~27-32% |
| K2 | Karakoram | 1954 | ~20–25% |
| Broad Peak | Karakoram | 1957 | ~5% |
| Gasherbrum I | Karakoram | 1958 | ~8% |
| Gasherbrum II | Karakoram | 1956 | ~2% |
| Everest | Nepal Himalaya | 1953 | ~0.5% (spring 2026 season) |
Everest is the clearest illustration of the pattern. Spring 2026 was the mountain's busiest season on record, with 1,008 summits including 274 climbers on top in a single day, yet only five people died — a season fatality rate under 0.5%. That isn't because Everest is inherently gentle; above 8,000m, it is not. It's because Everest now carries the heaviest investment in fixed ropes, forecasting and Sherpa-led route preparation of any mountain on Earth. The Karakoram 8,000ers get a fraction of that traffic, and a fraction of that infrastructure.
What This Means for Anyone Weighing a Himalayan Trip
What this means for trekkers
The lesson isn't Karakoram bad, Himalaya safe — Nepal's own Annapurna I carries the worst odds of any 8,000er on this list. The real variable is terrain plus infrastructure: a fixed-rope, forecast-supported, well-guided route is dramatically safer than an unsupported one, whatever range it's in. That's exactly the calculation behind Nepal's trekking-peak system: summits like Island Peak and Mera Peak sit well below 8,000m, run on established guided routes, and post fatality rates nowhere near this list, which is why they're the standard first step for climbers building toward serious altitude rather than an unsupported 8,000m expedition.
For trekkers who want to stand close to this kind of terrain without the objective risk, a route like the Ama Dablam Base Camp trek puts you in full view of 6,000m-plus Himalayan giants without any of the exposure described above.
