Start at the Col de la Vierge Clarisse.
(S/E) From the car park, head towards La Chapelotte (Red Ring).
(1) After walking for about 400m, take the ‘Sentier des Roches’ path on your right, marked with a Green Rectangle, until you reach the Grotte des Poilus.
(2) After the Grotte des Poilus, head back up the path you left a little earlier and turn right to reach the Croix Charpentier.
(3) At the Croix Charpentier, take the steep path which starts directly opposite (marked with a Yellow Triangle) towards the Pierre à Cheval. There is a viewpoint at the summit overlooking Pierre Percée and the lake. Follow this steep path to the next forest track.
(4) Continue to the right, following the Blue Crosses and heading towards the Roche de la Soye
(5) Turn left, heading towards La Menelle via La Roche de la Soye. Continue along the track down another steep descent to the D182.
(6) Follow the road for 500m towards Celles-sur-Plaine, passing the information and memorial centre for the Great War (1914–1918).
(7) At the fork with a fountain, turn right onto the ‘no entry’ path (except for residents), signposted with a Green Rectangle (Chemin de la Menelle) towards Pierre-Percée. Leave the fountain (decorated with flowers in summer) on your left and follow the path to the right which passes above the forester’s cottage.
(8) In the village, in front of the town hall, turn left and head down towards the lake along the small road that joins the D182A.
(9) Cross the road and follow the Red Ring signposts; this path runs alongside the lake.
(10) At a place known as ‘Les Ruines de la Xaveure’, continue to the right, heading north-east, following the MTB route markings (orange triangle and disc), which will take you back to your starting point, the Col de la Vierge Clarisse (S/E).
. I recommend this hike, but be careful not to buy waffles at Lake Pierced Stone because they are expensive!!!!!!
