(4) Heading south-west, the terrain becomes open and the path to the Col de la Fenêtre is clearly visible. At the first junction, take the path on the right, then after passing under a high-voltage power line, continue towards Plan de la Fenêtre, crossing several scree slopes. Join the path coming from Col de la Croix du Bonhomme. There is little elevation gain left to reach Col de la Fenêtre.
Enjoy the panoramic view of the Mont Blanc massif to the east and Beaufortain to the west.

(9) Head east towards Chenalettaz and you will come to another trail junction.
(10) Head north, begin the descent through the forest and reach L'Anery.
