Way to tell em , tiger ! <| sep |> From what I ' ve seen and read , it goes 1 . Everest has the most total deaths because it also has the most inexperienced mountaineers trying it . It isn ' t technically difficult , but more people die of exhaustion on Everest because of a lack of experience and physical training . 2 . K 2 is climbed by experienced mountaineers only , but has a horrendous mix of technical spots , as well as random chance , such as the Bottleneck and the serac . You can be the best of the best , but if a piece of ice falls off of that serac at the wrong time , in the wrong place , you ' re fucked . 3 . Annapurna I is avalanche country . A huge portion of the deaths are due to avalanches . They happen often , and all over the place . This means that it ' s even more random than K 2 .
