The deadliest 8,000-metre peak is not K2, and not in the Karakoram

Four of the fourteen 8,000ers sit in the Karakoram, and the range gets the reputation. The numbers, peak by peak, point somewhere else entirely.

Key facts

A high Karakoram peak under snow — four of the fourteen 8,000-metre mountains stand in this range — Four of the fourteen 8,000ers are here. Their records are nothing alike.

Of the 14 peaks above 8,000 m, four are in the Karakoram — K2, Broad Peak, Gasherbrum I and Gasherbrum II.
K2’s all-time fatality ratio sits around 20–25%, pulled toward ~13% by the record commercial seasons of 2022–23.
Gasherbrum II, the most-climbed Karakoram 8,000er, runs about 2% — among the lowest on the list.
The deadliest 8,000er by percentage is not in the Karakoram. It is Annapurna I, in Nepal.
None of these figures describe trekking. They describe climbing above 8,000 m.

The Karakoram is not uniformly deadly, and the single most lethal 8,000-metre peak is in Nepal rather than Pakistan. The range’s reputation is earned, but it is concentrated in specific terrain on specific mountains rather than spread evenly across it.

Pakistan’s Broad Peak claimed at least four more lives in an avalanche near Camp 3, reviving a familiar shorthand: the Karakoram is the world’s deadliest range, full stop. Seven decades of summit-and-death records tell a more specific and more useful story.

Four of the fourteen are in the Karakoram

K2, Broad Peak, Gasherbrum I and Gasherbrum II are the Karakoram’s share of the 8,000-metre list. The other ten sit in the Himalaya proper, most of them in Nepal.

That split matters because the two ranges are usually discussed as though they were rivals with a single score each. They are not. Within the Karakoram the spread between its safest and deadliest peak is wider than the gap between the ranges.

K2’s danger has an address

Most of what makes K2 lethal happens in one place: the Bottleneck, a narrow ice-choked couloir at roughly 8,300 m directly beneath a hanging serac wall. Climbers pass under it, slowly, with no way to hurry and nowhere to move sideways.

A steep ice couloir of the kind climbers must pass slowly and without shelter — The Bottleneck sits at 8,300 m, under a hanging serac.

A collapse there in August 2008 killed eleven climbers in a single day, the deadliest incident in the mountain’s history. The serac does not care how skilled the party below it is, which is why K2’s number resists the usual explanation that experience lowers risk.

Broad Peak kills in a different way

Broad Peak’s risk is exposure over time rather than a single hazard overhead. The summit ridge is a long, exposed traverse where climbers move for hours with little fixed protection, in a zone with almost no permanent rescue infrastructure.

Climbers moving along an exposed snow ridge, the kind of long traverse that offers no protection for hours — Hours of exposure, almost no rescue infrastructure.

Two mountains, two entirely different failure modes, both inside the same range and both feeding the same statistic. A range-level number cannot tell you which one you are signing up for.

Gasherbrum II is the counter-example

The most-climbed Karakoram 8,000er has one of the lowest fatality rates on the entire list, at roughly 2%. It sits in the range that everyone calls the deadliest.

A roped team ascending a snow slope — the most-climbed Karakoram 8,000er is also among the safest on the list — The busiest peak in the range is among the safest anywhere.

Gasherbrum II is the number that breaks the headline. If the Karakoram were uniformly lethal, its busiest peak would not be among the safest 8,000 metre mountains in the world.

The deadliest one is in Nepal

By percentage, Annapurna I in Nepal’s own Himalaya is the deadliest 8,000-metre peak, not K2 and not anything in the Karakoram. It is also far less famous for it, because fame follows height and difficulty rather than ratio.

The Annapurna massif in Nepal, whose highest summit carries the worst fatality ratio of any 8,000-metre peak — Annapurna I. Less famous, and worse.

That is the most useful correction in this piece. “Karakoram versus Everest” is the wrong frame entirely — the answer is neither.

Why the all-time number misleads

A fatality ratio is deaths divided by attempts, so it moves when the number of attempts changes, without anything on the mountain changing at all. K2’s record commercial seasons in 2022–23 added a large number of summits and pulled its running figure from the 20–25% all-time range toward roughly 13%.

The mountain did not get safer by a third in two years. More people climbed it, more of them lived, and the denominator moved. Read any of these ratios as a description of the era they were accumulated in, not as a fixed property of the rock.

What this means for anyone weighing a Himalayan trip

If you found this while working out whether trekking in Nepal is dangerous, none of these numbers apply to you. They describe climbing above 8,000 metres with supplementary oxygen, fixed rope and a summit push through the death zone.

Trekkers walking a Nepali lodge trail far below the climbing zone, where none of these fatality figures apply — This is the trek. None of those numbers describe it.

A lodge trek to Everest Base Camp tops out at 5,364 m and involves walking. So does Annapurna Base Camp at 4,130 m. The peak whose fatality ratio you just read about is visible from some of these trails, which is exactly why the dread transfers — and it should not.

What we would actually say

The honest hierarchy: trekking peaks like Island Peak and Mera Peak are a real step up from trekking and a different universe from an 8,000er — they need crampons, a rope and a guide, not a Karakoram CV. If a company quotes you an 8,000-metre expedition using a trekking-peak price and timeline, that is the warning sign, not the mountain’s statistics.

The range is not the unit of risk. The route is.
