Access: From Arboras, take the Departmental Road 9 towards Montpeyroux Gignac.
After a bus stop, take the D122 on your left towards Saint-Jean-de-Buèges, La Font du Griffe and Les Lavagnes. Continue along this road until you reach a flat area with a pink graffiti sculpture. Park at the Col de Cocalières dolmen.
(S/E) At the signpost, take the track.
(1) At the fork, continue straight ahead and pass a large farm building. Continue along this track for about 200 metres until you reach the next crossroads.
(2) At this junction, take the small path on the left. Follow the path. You will then walk along the Ruisseau du Joncas stream, sometimes in the stream, sometimes beside it. After about 2 km, look out for a cairn on your left.
(3) Take the path on the left that climbs up the mountain. There is a blue dot on the rock. Follow the trail, looking for signs of other hikers (there are quite a few in this area). The entrance to the cave will come into view, and it is easy to climb down. Return by the same route until you reach the path you left.
(3) Follow this path to the left.
(4) Almost at the top, leave the track on the left and take a path that descends to the right at the bottom of a hollow. From there, you can see the path that will take you back up to a large track.
(5) Turn right and follow this track for about a kilometre.
(6) Take a path on your right marked with a cross and a sign prohibiting motorcycles. Further down, you can see the top of the Cirque de l'Infernet below. This pleasant little path leads to a wide track.
(7) Continue to the end of the hairpin bend and follow this track to the right.
(8) Further down, leave theGR® for a small path on the right, which allows you to avoid this long track for a while. Leave two paths on the left to rejoin the track further down, at the Neolithic enclosure.
(9) Return to theGR®653. Follow the GR®. In a wide curve to the right, leave the track on the right and continue on the PR®. Reach the route taken at the start.
(1) Turn left to return to the Col de Cocalières (S/E).
