To get to the starting point, from the village of Chastreix, take the D615 towards the Chastreix-Sancy resort. Follow it for about 5 km and park in the car park before a hairpin bend.
(S/E) Take the track that starts at the hairpin bend in the road. Follow it to a barrier at the edge of the forest, noting the rock (volcanic bomb?) on your left just before the edge of the woods.
(1) Go through the gate and continue along the track. Go through the barrier at the entrance to the woods and continue uphill. Walk past a ruin on your right and you will soon come to a fork in the road.
(2) Turn right, then left about a hundred metres further on. At the next fork, turn right and you will soon reach the next one.
(3) Don't hesitate to make a return trip to the edge of the woods to enjoy the view from the chicane. On your return, continue along the path on the right and head for the next fork.
(4) Continue straight ahead to the edge of the woods with an orientation table on your left.
(5) Enter the mountain pasture dotted with large erratic boulders, cross it on a slight descent, then exit the park and head for the stream.
(6) Cross it via the footbridge and continue along the wooden walkway that passes over the various resurgences of the Source de la Fontaine Salée until you reach a track.
(7) Turn around and return to the fork after the orientation table.
(4) Leave the route you have already taken and continue to the right until you reach the edge of the forest.
(8) Turn right into an area of broom, which tends to hide the path for a short distance. Cross the bottom of the valley and continue on the other side until you reach the next fork at the end of the mountain pasture.
(9) Continue straight ahead, uphill, on an old track, then along the hillside until you reach a picnic area.
(10) After passing through the gate, turn immediately left. At the next fork, turn right, join the road and follow it carefully to the left until you reach the car park after the hairpin bend (S/E).
