There are a few parking spaces in front of the town hall, and a parking lot just behind. It's a good starting point for hiking, but we prefer the Via Ferrata parking lot at the exit of the village.

As you climb up to the Col de l'Alpe, you will find a summit cross dating from the early 20th century. Erected in 1926, it was built to commemorate local climbers and hikers who lost their lives in the Alps.

Perched at an altitude of 1,799 meters under the rocks of Belles Ombres, the pass is one of the gateways to the Hauts de Chartreuse nature reserve. A few meters from the pass is the cross of the same name.
