Tour Noir, Mountain summit in Valais, Switzerland

Tour Noir is a summit of the Mont Blanc massif on the Swiss-French border, standing between the Aiguille d'Argentière and Mont Dolent, south of the Aiguille de l'A Neuve. Its south-west side drops to the glacier of the same name, its north-west side to the Glacier des Améthystes, and its east side to the Glacier de l'A Neuve.

The summit formed through tectonic processes during the creation of the Alps millions of years ago. This geological history shaped the granite structures that now define the mountain's character.

The name Tour Noir, French for "black tower", refers to the dark rock of its north-west face, seen from the Argentière glacier. The summit lies on the Swiss-French border between the Aiguille d'Argentière and Mont Dolent, and is climbed from the Saleina side or from La Fouly in the Ferret Valley.

The mountain is accessed from La Fouly village, which has mountain guides and equipment rental services for technical climbs. Visitors should prepare for serious alpine climbing and bring complete mountaineering gear.

Tour Noir sits between the Aiguille d'Argentière and Mont Dolent, and its slopes feed three glaciers: the Tour Noir glacier to the southwest, the Améthystes glacier to the northwest and the A Neuve glacier to the east. The name Noir refers to the dark rock of its faces, which stand out against the snow and ice around them.
