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.

Magnificent and relatively easy pass, with basic fitness. Offers a magnificent view of Mont Blanc. Be careful though, the Chaos and the Col are currently completely covered in snow. Being in a group, I did not attempt the ascent of the Col which, without equipment, can be particularly slippery and dangerous. Possibility of going back down via Prayet towards Saint Pierre en Chartreuse. Tested in November, however, no problems observed, very accessible.
