At the end of the regional road, follow the farm road on the left that, crossing the pastures, will lead you till the Chamolé chairlift arrival. From here continue on the path that leads to the homonymous lake. After the lake the path climb till the Col Replan (here you can find a hand-painted ceramic plate as a part of the didactic-naturalistic “Marmott Trail”). From here you can go down till Plan Fenêtre.
