This sector is located on the right bank of the river Essonne, to the opposite of Le Rempart d'Argeville, between Nanteau and Chantambre. The simplest access consists in taking the road of Buthiers (from Chapelle-la-Reine or by the D410) but just before the village, take the D53a in direction of Nanteau and Villetard for 4km900. Park just after a marked bend on the right, along the river (the boulders are visible from road). From the parking lot, take a path for 50m to the East, and then left in directly in the slope. Most o the problems are near the top of the hill. Caution! This sector is on a private plot, reserved to hunters in winter. One should be particularly discrete and respectful of the site, avoiding especially week-ends and hunting days.
