Description of the route

When you get to Saint-Rhémy, continue by car along the Gran San Bernardo road until you get to Baou, about 2 km from the mountain pass on the border. Park the car and leaving the pasture on the left, take route 13A which bypasses a path on the left, crosses a stream and goes up to a plateau surrounded by the peaks of Mont Fourchon, Drône and Grande Chenalette. When you come to another crossroad, keep on the same trail on the right and after crossing back over the stream, go across alpine meadows then debris terrain until you come to Fenêtre de Ferret.
It is possible to continue into Swiss territory along the red and white trail, which takes about 40 minutes to reach the Ferret lakes.
