Why some 8,000-metre peaks get climbed thousands of times and others almost never

People talk about the fourteen 8,000-metre peaks as if they were one brutal club, but the climbing record tells a very different story. Everest has been summited more than 12,000 times. Cho Oyu, its quiet neighbour, has thousands of ascents too. At the other end, Annapurna I and Kangchenjunga have only a few hundred summits each across the whole history of mountaineering. The gap between the most-climbed and least-climbed eight-thousanders is enormous — and it is not really about height. It is about danger, access, and whether a mountain can be guided.

The most climbed, and why

Everest is in a league of its own, with over 12,000 recorded ascents and more than 7,500 different people having reached the top. That is not because it is easy — it is because it is the highest, so it draws the ambition and the money, and decades of commercial operation have wrapped it in fixed ropes, stocked camps and Sherpa support. Second on the list is Cho Oyu (8,188 m), widely regarded as the most accessible 8,000-metre peak: a non-technical standard route, a drivable approach on the Tibetan side, and a strong safety record have made it the classic “first 8000er.” After those two the numbers fall away sharply. Gasherbrum II in the Karakoram is one of the few others with roughly a thousand ascents; most of the fourteen are counted in the hundreds.

These figures come from a single compiled dataset (MountainIQ, drawing on the Himalayan Database) so the peaks can be ranked side by side; they are cumulative and keep growing every season, and different sources count summits and deaths slightly differently. Everest’s “12,000+” total from the Himalayan Database is compiled to a later cut-off than the comparative row above, which is why the two Everest numbers differ.

The least climbed, and why

The bottom of the list is telling. Annapurna I, the very first 8,000er ever climbed, has among the fewest total ascents of all fourteen — and the highest death rate, roughly one fatality for every four summiteers. Its north face runs beneath hanging seracs that fall on their own schedule; skill does not remove that hazard, so climbers stay away. Kangchenjunga, the third-highest mountain on Earth, is remote, storm-prone and long, with only around 300 ascents. The technical Karakoram giants — K2, Nanga Parbat, Gasherbrum I — combine severe difficulty with a harsh, hard-to-reach range. In short, the least-climbed 8000ers are the ones that cannot be tamed into a guided, roped, high-success expedition. We break down why Annapurna I is the deadliest 8000er by fatality ratio in its own piece.

What the gap really measures

The lesson of these numbers is that summit count is a measure of accessibility, not of how “hard” a mountain feels to stand beneath. Height barely predicts popularity: the 8,188 m Cho Oyu is climbed a hundred times for every ascent of the shorter, deadlier Annapurna I. What a peak’s numbers actually track is whether it has a route that can be secured, an approach that can be reached, and a hazard profile that a well-run expedition can manage. Where all three line up, thousands go. Where objective danger dominates, the mountain stays empty — and, grimly, deadly.
