First ascent
In 1865 Amé Gorret, Martino Baretti, and Jean-Pierre Carrel reached a subsidiary summit on the crest of the mountain, which they subsequently dubbed Pic du Retour. Two years later, Daniel Ballay and Michel Payot guided Douglas Freshfield, C. C. Tucker, T. H. Carson, and J. H. Backhouse to the main summit.
