Grande Fourche

Grande Fourche is a mountain summit in the Mont Blanc massif located in the Valais Alps. It sits between two major glaciers and forms part of a dramatic rocky ridge in this high-altitude region.

The summit became an important boundary marker between Switzerland and France during the establishment of Alpine borders. The border line was formally defined through international agreements that shaped the modern Alpine frontier.

Local mountaineering groups maintain detailed records of ascents to Grande Fourche, contributing to the documentation of Alpine climbing achievements through generations.

Reaching this summit requires advanced climbing and glacier travel skills from visitors. The approach demands careful preparation and familiarity with alpine conditions, as weather can change rapidly and glacial hazards are common.

The two glaciers on opposite sides create distinctly different climbing conditions on the eastern and western faces. These differences influence not only the difficulty level but also the ideal timing for an ascent.
