Park on the side of the D8F, about 750 m after the Col de Latrape when coming from Aulus-les-Bains.
(S/E) Take the path that climbs up the hillside (north-west). It climbs steadily to reach a small pass.
(1) Descend slightly and turn left, following the edge of the woods (markings not very visible), climb up through a field of ferns before beginning a descent that will take you to Turon d'Isaac (old barns that are starting to fall into ruin).
(2) Go through the gate on the right. The path passes under the two barns and continues into the woods (at a ruined barn, Mont Valier comes into view). Go past the gate of a renovated barn and turn left.
(3) You will come out onto a track; follow it to the left. At the next intersection, continue straight ahead.
(4) Turn left (note thefirst sinkholes on your right). Continue straight ahead on the path and keep to the path lined with low walls to reach a new intersection.
(5) Go left at Gouffre d'Ajéou with its stream that disappears into the bowels of the earth... Return to the path.
(5) Stay on the main path between the low walls (south-west). Pass by Fontaine du Trou. The path climbs to a beautiful viewpoint under a renovated barn. Pass in front of the barn with the flat tile roof and turn right onto the path at the edge of the forest (not very visible).
(6) A small sign indicates that the path turns left and then climbs to reach a track.
(7) Continue along the track opposite and quickly take a path on the left to return to Turon d'Isaac.
(2) Follow the same route back to the car park on the edge of the D8F (S/E).
