The route
Starting from the Saint-Guérin dam, the loop climbs to the ridge of the Mont des Acrays (2,194 m) via the Passage de la Charmette. From the Passage du Miraillet, the view opens onto Lac de Roselend and the Mont Blanc massif.
The path is very busy and damaged in places. There is no water on the route. In summer 2026, the free Beaufortain shuttles served the Saint-Guérin dam.
What you see on the way
