With the end of the lockdown we decided to push out a little bit to this classic switchback descent. Unfortunately it started to rain, hard just as we were arriving.

Follow the Pierre Grosse trail. At the end of the 33 hairpins take the right fork rather than crossing the torrent on the left. After about 20 meters of descent cross the Corbonne stream.

From the Massons car-park follow the signs to the "La tour d'Arces" then "Pierre Grosse"; carry on past the Pierre Grosse on the left to the end of the trail.
