This is the classic and best-known route to Aletschhorn. It is a long high-alpine ascent on snow, ice, and mixed terrain, usually starting from the Hollandia Hut. The route is generally less technical than the steep north-face lines, but it remains serious because of its length, altitude, and glacier travel. The upper mountain can involve exposed ridge climbing and route-finding in poor visibility. Crevasses and snow conditions on the approach are important objective hazards. It is typically climbed as a two-day outing with an overnight at the hut.
