Aletschhorn, Mountain summit in Valais, Switzerland
The Aletschhorn is a mountain summit in the Valais Alps rising to 4,193 meters and featuring steep rocky sections along its ascent. Multiple climbing routes cross glaciated terrain and exposed ridges to reach the peak from different starting points in the region.
The first recorded ascent took place in 1859 and established the peak as a significant goal for alpine explorers in the 19th century. Local mountain guides who completed that climb later led many other expeditions on the mountain.
The mountain draws climbers from around the world and stands within a UNESCO World Heritage site that reflects the geological and natural importance of the Swiss Alps. The area maintains strong ties to traditional alpine guiding communities that have shaped this landscape for generations.
The climb typically takes two days and requires alpine equipment as well as mountaineering experience. Starting points include towns such as Fiesch or Bettmeralp, from which routes lead into the mountain area.
The mountain sits directly adjacent to the Aletsch Glacier, the largest glacier in the Alps, which shapes climbing conditions through changing seasonal periods. Summer and autumn bring significant shifts in glacier conditions that affect the difficulty of the route.
