Park in the Agachou car park, 500 m before the Résidence Lou Castel de Casteljau along the D452.
(S/E) Take the path at the end of the car park on the south side, which is very steep. Join the Chassezac river. At the bottom of the descent, follow it for a while, pass by a ruined house and gently climb back up towards the ruins of Château Cornilhon. Pass them and take the path on your left, which is very steep.
(1) Take the road on the right and cross the Salindres river via a concrete ford. Head north, passing Céven'Aventure, and cross the river again just before crossing it a second time.
(2) Turn right onto the uphill path and follow the numerous natural steps through the heath. Join the D452, cross it carefully and take the yellow-marked PR® path opposite. A hundred metres further on, you will rejoin the D452.
(3) Follow it for a few metres to reach the Jean Froment memorial and thefirst drystone shelter. Retrace your steps, cross the road and follow the yellow-marked path to the left again. Continue until you reach a crossroads of paths in a bend.
(4) Leave the yellow markings here and turn left onto the path marked with a yellow and white cross. You will soon reach the D452. Follow it for about 100 metres until you reach a crossroads.
(5) Turn right into the oak forest and climb up to Serre de la Ramade.
Be careful here: there are places where the path is not very visible: follow the cairns put in place by hikers or use the Visorando app or a GPS. The path continues downhill and leads to the D 452.
(6) Follow it to the left, heading north. At a bend in the road on the left, take the path opposite. You will soon find another drystone shelter on the left. Continue along this track until you reach an opening in the wall.
(7) Take the path on the right, heading east, until you reach another drystone shelter, then turn left towards a drystone shelter in poorer condition. Turn right here to join a wider path.
(8) Turn right heading south, then at thefirst crossroads, take the path downhill on the left. Wind your way between oak trees and rocks to reach a flat area. You will see a shallow cave on the left, which is easy to visit. Stay on the left edge of the woods to find the start of the path.
(9) Head left along the small uphill path, known as the Sentier Roche: be warned, this crossing is quite physically demanding. Cross a wood that bears a striking resemblance to the Bois de Païolive. Pass under a rock arch to reach a sharp limestone pavement. Cross it lengthwise and look for the yellow markings to leave the pavement. Continue along the path that winds between rocks and holm oaks. Exit onto a private road (authorised passage) and follow the instructions on the sign.
(10) Turn left and you will soon reach the hamlet of Coudon.
(11) Take the small tarmac road on the right for about a hundred metres. Turn onto the path on the right going up the embankment. Pass the house in Montchamp and you will reach a T-junction on a flat section.
(12) Take the path downhill to the left, continue this long descent with numerous scree slopes to the intermittent Merle stream and, after crossing it, you will come to a small tarmac road.
(13) Follow it to the right and you will soon reach a bend.
(14) Leave the road and take the path on the right, first downhill and then uphill, towards the cliffs overlooking the Chassezac. You will reach the top of the Chaulet climbing site.
(15) Keep to the left and enter the most physically demanding section, which involves climbing and descending among rocks and holm oaks. After a fairly technical descent, cross the small (often dry) Ceyrèdes stream.
(16) Head left towards the south to follow the climbing sites and come out at a very narrow passage between two rocks.
(17) Turn right to reach a crossroads with signs for the Agachou car park and head towards it (S/E).
