Gross Fusshorn, Alpine summit in Valais, Switzerland.

Gross Fusshorn is a 3,627-metre peak of the Bernese Alps in the canton of Valais, standing above the Oberaletsch Glacier. Its south ridge carries the Fusshörner, a group of smaller peaks, and a glacier called Driestgletscher lies on its east side.

The first documented ascent occurred in 1895 when Miss Bertram Hopkinson and her family reached the summit. This early mountaineering expedition was part of the region's growing Alpine climbing tradition.

The name combines German Fuss (foot) and Horn (horn), a common suffix for peaks in the Bernese Alps. The Fusshörner, a group of peaks on the south ridge of the Gross Fusshorn, share the same root. The mountain rises above the Oberaletsch Glacier in Valais, and the Driestgletscher lies on its east side.

The summit is reached from the Oberaletsch Glacier side, on the west, or past the Driestgletscher on the east; both approaches cross glacier ice, so rope, crampons and glacier travel experience are needed. The Fusshörner peaks on the south ridge stand between the two sides. Plan for the Valais location, where average annual precipitation reaches 2,221 mm.

The mountain gets its name from multiple smaller peak formations along its southern ridge, each known as individual Fusshörner. This collection of diverse summits makes it an interesting exploration destination for experienced climbers.
