(S/E) Take the grassy path under the cross. Begin a long climb through meadows and undergrowth, ignoring all paths that branch off to the right or left. You will come out onto a tarmac road and quickly reach the Chapel of Notre-Dame du Bon Secours on your left.
(1) Ignore the two private paths on the left and take a small path to the right of the barrier. Climb up through the meadow and then through the undergrowth, which quickly joins a forest track.
Take this track to the left and continue straight ahead, ignoring the paths that branch off to the right and left. After a sharp right-hand bend, continue to the ruins of the old monastery, where you will see a signpost.
(2) Turn left to reach the Saint-Médard Chapel. Enjoy the magnificent view of the syncline from here.
(3) Return to the previous crossroads.
(2) Take the path on the left that descends along the ridge to Pas Court.
(4) Turn right towards Pas Saint-Michel. Atthe first crossroads, turn left and ignore the path that descends to the right. At the hairpin bend, turn left and climb up to Pas Saint-Michel. Change sides here to descend and reach Pas de Faucon.
(5) Descend the north slope via a small, very steep winding path. Take care in wet weather. Continue until you reach a stony path. After a sharp left turn, take the path on the right to reach Blache Ronde.
(6) Take the tarmac road on the left and descend to the Bourbousson farm. Below the farm, continue along the tarmac path on the right towards the château to return to the Piegros sheepfold car park (S/E)
some sections are very tricky: steep slopes with stones and roots, so there is a risk of falling!
