Route designed by Christophe Stahl:

This 100 mile route starts and ends at Hotel Esprit Montagne in La Chapelle d'Abondance (Chablais Mountains, Haute-Savoie). It consists of 2 loops, one south of the hotel and one north of the hotel. So half way you come back to the hotel to start the second loop. It's a self navigation route with mostly trails but also parts where there is no trail and you walk trough the fields or over rocks. The climb to Fenêtre d'Ardens is a steep one, there is an iron cable for the last 20m straight up. So some climbing skills are required.
