The Col du Pillon connects the cantons of Vaud with the canton of Bern. The pass is located directly on the Les Diablerets mountain range, which is heavily frequented by tourists. Accordingly, expect some traffic on the road. The climb from Aigle is nevertheless well worth it, taking you through a long stretch of diverse mountain landscape.

The climb to the pass is done gradually on the Swiss side, but can still be strewn with snow at the start of the season. The French side offers beautiful, slightly steep green mountain pastures. A few mountain huts are accessible on the way, which can provide shelter in bad weather.

This pass is ideally located at the start of the GR5. It also gives access to the very beautiful ridges of Velan which give aerial and panoramic views of Lake Geneva, the cornettes de Bise and the Bise valley.

Very beautiful pass, very frequented by ibexes. From here the climb to the Cornette de Bise is a little steep but without technical difficulty.

The Pas de la Bosse is a pedestrian pass at 1,816 meters above sea level. It communicates the valley of Bise and the valley of Abondance. Take the time to admire the granite bars that tear the lawns of the massif. This landscape that surrounds the valley almost looks like a circus. It's splendid !
