Incredibly beautiful road, and quite demanding on gravel

Very steep, loose gravel, official XC E-MTB trail. If you like pushing your bike for a few hundred meters, this is a great trail!

Little-known and little-frequented pass, the climb is done alone and without a sound in the forest. The view is magnificent and on arrival, the refuge allows you to have a small drink (⚠️payment by species only). The road is in poor condition and it can be disturbing on the way down. If you have a Gravel and courage, the thirst route (Gravel/mountain bike path) allows you to reach the Col des Aravis and is magnificent. Enjoy your climb and for more advice, follow us on Komoot and Instagram @chouchou_team
