These large cliffs indicate that this mountain is forclimbing enthusiasts. Hiking is possible but it’s frustrating to stop at the foot of the limestone cliffs. Climbing this mountain is only for climbers of a good level, otherwise the presence of a mountain guide is necessary.
If there is any snow left, you must be careful with the lapiaz which can hide holes under the snow bridges. The approach to the mountain is either via the Nant d’Alex valley or via the Aulp chalet. Before setting off on a hike, find out about the weather conditions, which can change rapidly at this altitude.
