Saint-Rémy lès Chevreuse
This very small sector is composed of a few problems on the boulder of "la Tête de Serpent" in the forest above the district of Le Rhodon. From the centre of Saint-Rémy, take the direction of Milon la Chapelle by la rue de Port Royal and park the car in that one or la rue Hoche or l'avenue d'Assas. Come back to le Chemin de la Butte aux Buis (that goes up from la rue de Port Royal) and take a path in the forest to the right. The boulder is visible 300m further on the left up the slope.
