Randonnée - La Chaux summit

Isenau - Col des Andérets - Col d'Isenau - Sommet de la Chaux - Arpille - Isenau

A moderately difficult route with different views of Les Diablerets, Pays d'En-Haut and Lake Arnon (Arnensee).

From Isenau, take the small road for approximately 300 metres to La Marnèche and then the Isenau Mountain Chalet. Then follow the footpath to Col des Andérets and fork left to Col d'Isenau. Then start the climb to the La Chaux Summit. The route continues along a ridge then into a little cirque to Arpille. From there, continue on the narrow path that crosses below the summit of La Chaux to the Isenau Mountain Chalet, and then to Isenau.

In Isenau, there are 2 options:
No. 1: return to Col du Pillon via Lake Retaud (approx. 1 hr)
No. 2: return to the village by the Crêtes path (approx. 1 hr)

Try some of the local produce at the Isenau Mountain Chalet (cheese, serac, etc).
Stop at the La Marnèche snack bar with its beautiful terrace offering stunning views of the Les Diablerets mountains.
