You can park on the side of the D36, between Cellefrouin and Saint-Mary, on a clear, freely accessible plot on the left-hand side when coming from Cellefrouin, near the 129 mark and a small abandoned house.
(S/E) Follow the road to the right (north) and, after a few dozen metres, cross it carefully and take a path on the left that enters the woods. Ignore a path on the left and, at the next crossroads (elevation 126), go straight ahead.
(1) Shortly afterwards, take a forest track on the left. At the edge of the road, turn left onto a limestone track.
(2) At the next intersection, turn left and, at the fork shortly after, turn right. Continue straight ahead, heading south, and ignore the paths on either side. At the crossroads (elevation 140), continue straight ahead for about 200 m until you reach the next crossroads in a clearing.
(3) Then turn left (east). Ignore a path on the right and you will soon reach another intersection.
(4) Turn left, go straight ahead, heading north, and ignore any turnings on either side. At the crossroads (elevation 136), continue straight ahead and you will immediately reach another crossroads.
(5) Then turn right. Cross the D36 carefully and continue on the road opposite.
(6) At the next intersection, turn left at an acute angle. Go straight ahead to the edge of the D36 and return to the starting point (S/E).
