Vallée Ronde
This small sector gathers a few problems, half of them lichened (April 2016). Access : from Arbonne, follow the D64 in direction of Achères and park the car near the top of the 17 bends (same parking lot as for Le Bois du Rocher). Follow Le Chemin des Cassis for 300m : the boulders can be found on the left of the path, 200m before the motorway.
