Geltenhorn, Mountain summit in the Bernese Alps between Valais and Bern cantons, Switzerland

The Geltenhorn (also spelled Gältehore) is a mountain of the Bernese Alps on the border between the Swiss cantons of Bern and Valais. It belongs to the Wildhorn massif and lies approximately halfway between the Arpelistock and the summit of the Wildhorn. Its north side is covered by the Geltengletscher glacier.

The sources record no first ascent or climbing history for the Geltenhorn; its documented past is cartographic and administrative. The summit lies on the Bern–Valais cantonal border, and the mountain belongs to the Wildhorn massif, between the Arpelistock and the Wildhorn summit. Its north side carries the Geltengletscher, the glacier that defines the peak's northern approach.

The name appears in two forms, Geltenhorn and Gältehore, reflecting the German-speaking Bernese side and the Valais side of the border ridge. The Geltengletscher on the north flank feeds the valley below, and the massif is climbed from both cantons, so the peak is a shared reference point for Bernese and Valaisan mountaineers.

This ascent requires mountaineering experience and proper gear due to steep sections and glacier travel. Villages in the valley can help with guides and equipment rentals to prepare for the climb.

The glacier on the north side is called the Geltengletscher, and it is this ice cover that separates the Geltenhorn from the Arpelistock and the Wildhorn massif. The peak is also spelled Gältehore in local usage.
