Avoid leaving the paths and keep your dog on a leash from April to July.

This sector, mainly exposed to the North but quick-drying in its upper part, gathers 50 problems, most opened by Frédéric Buc.
Access: on the road from Courances to Arbonne, park the car at the aqueduct. Follow the underground part of that one by a path, up to the stairs of Montrouget. Go around the hill by the right (white marks) and arrive at Le Chemin de la Roche qui Tourne near Le Carrefour des Fauves. The boulders are on the East of that crossing, all in the plot 7, except Sinus-X which is located in the plot 6.
