Leave the car park and pass in front of the "Maison pour tous" then in front of the town hall.
At the crossroads, turn right towards Rue de l'Eglise. Stay on the asphalted road that climbs up to the wall made of large boulders and turn right on the dirt road that climbs.
At the top of the path, at the cross, take the track that heads off to the right and follow it.
