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.

Climb to the Col du Barioz via Les Fontaines and Le Charpieux. A technical climb after Les Perrins requires vigilance and some pushing. Please note: Passage after Les Perrins may be blocked during the summer by an electric sheep fence.
