Aiguille de Roc, Alpine summit in Aiguilles de Chamonix, France

Aiguille de Roc is a 3409-meter peak in the Mont Blanc massif with nearly vertical rock walls. These sharp, dramatic faces make it a technical climbing destination that requires serious Alpine skills and experience.

The first ascent of Aiguille de Roc was made on 6 August 1927 by Alfred Couttet, Miriam E. O'Brien and Georges Cachat, after three failed attempts on 6, 13 and 29 August 1926. The 1926 tries involved Miriam O'Brien, her brother Lincoln O'Brien and another guide, then O'Brien with Vital Garny. The detached rock pinnacle rises on the south-east flank of the Aiguille du Grépon.

The peak draws mountaineers from around the world who come to test themselves on difficult rock walls. Local guides use this location to teach and mentor younger climbers in traditional Alpine techniques.

This climb demands proper mountaineering gear, strong fitness, and solid technical climbing ability. Most visitors work with mountain guides and plan for multiple days to acclimatize and manage the demanding ascent.

The Refuge de l'Envers des Aiguilles sits about 550 meters below the peak and serves as a shelter point for climbers. This mountain hut provides a crucial resting spot and supplies for those pushing toward the summit.
