Aiguille du Chardonnet, Granite summit in Chamonix-Mont-Blanc, France.

Aiguille du Chardonnet is a granite summit in Chamonix-Mont-Blanc that reaches 3824 meters and displays a distinctive pyramidal shape. The peak consists of solid granite formations with steep faces on all sides and offers several climbing routes of varying difficulty.

The first ascent was made on 20 September 1865 by R. Fowler, M. Balmat and M. Ducroz. The west ridge, long taken as the normal route, was first climbed on 1 August 1879 by P. Thomas, J. Imboden and J. Lochmatter, and the Forbes Arete on 30 July 1899 by L., H. and T. Aubert with M. Crettez. A winter ascent was recorded before 1914.

The peak forms part of the Mont Blanc massif and serves as a training ground where climbers from around the world test their skills before attempting harder expeditions. The granite faces here have become known among the alpine community as essential stepping stones for progression.

Climbers can reach the peak via two main approaches: the Cabane Albert Premier from the French side or the Cabane de Trient from the Swiss approach. The best season for climbing is during the warmer months when conditions are more stable and the terrain is more passable.

The Forbes ridge and Eperon Migot routes are among the most challenging climbing routes on the peak and demand advanced technical skills. These lines are favored by experienced climbers because they offer real difficulty and see less traffic than the standard approaches.
