Departure from La Ferrière (Isère) (Isère)
A circular walk through a rocky landscape shaped by glaciers and dotted with mirror-like lakes. After the peaceful mountain pastures of Lac Léat above the Haut Bréda valley and then the Combe Grasse, the walk takes you to the passes and peaks surrounding Puy Gris before descending towards the scenic setting formed by the lakes of Grande Valloire.
The hike can be done with an overnight stay in a mountain hut and can be combined with the easy ascent of Puy Gris: see the ‘During the hike’ section.
