Aiguilles Rouges d'Arolla, Mountain summit in Valais, Switzerland

The Aiguilles Rouges d'Arolla form a mountain chain in the canton of Valais, running between the Lac des Dix to the west and the village of Arolla to the southeast. Three summits are distinguished: the main central summit at 3,646 m, a north summit at 3,594 m and a south summit at 3,584 m, the last set apart by a saddle and reached over a ridge studded with gendarmes. The group belongs to the Penninic Bündnerschiefer nappe, and glaciers cover parts of its flanks.

The massif's three summits were distinguished in early Alpine surveys: the main summit at 3,646 m, a north summit at 3,594 m separated by a shallow notch, and a clearly detached south summit at 3,584 m. The full ridge traverse, graded IV+ at one passage and otherwise III and II, became the rewarding objective. Geologically the group belongs to the Penninic Bündnerschiefer nappe.

The name Aiguilles Rouges refers to the red rock of the three summits, which rise between the Lac des Dix and Arolla. Climbers distinguish a main summit at 3,646 m, a north summit at 3,594 m and a clearly separated south summit at 3,584 m. The full ridge traverse, graded IV+ at one point and otherwise III and II, is the rewarding objective.

The group lies between the Lac des Dix to the west and Arolla to the southeast. The traverse of the whole ridge is the only truly rewarding route: grade IV+ at one passage, otherwise III and II, with many gendarmes on the ridge above the south summit (3,584 m). The north summit reaches 3,594 m.

The mountain ranks as the 23rd highest peak among 161 in the Hérens massif and holds position 63 out of 10,817 mountains in Switzerland.
