Pleasant walk along the path, which once led to the Chalet de Lognan across the Glacier d'Argentière.
From the village of Le Planet, take the wide path that crosses the Petit Balcon coming from Le Tour and Argentière. Continue straight ahead in the forest and at the next fork in the road, continue straight ahead towards the moraine, crossing numerous couloirs under the Rocheray: a climb leads to the top of the place called the Pierre à Bosson: viewpoint.
DO NOT GO BEYOND: DANGER!
