Park in the car park by the village hall, on the edge of the D629, south of the village.
(S/E) Leave the car park, head back towards the village centre and cross to the other side of the Voûte Vauban, without continuing any further.
(1) Immediately turn right onto the dirt track. This section ofthe GR®7, Chemin de la Rigole, runs between two rows of trees and is known as Chemin d’en Bosc after passing the hamlet of the same name. You’ll come out onto the Route du Barrage.
(2) Cross it, continue straight ahead and, 50 m further on, leave theGR® by turning onto the path on the left,PR®. Descend to the path known as Chemin des Pêcheurs, follow it to the left to return to the Route du Barrage.
(3) Head right, towards the dam. Follow this section which crosses the Sor; at its end, the Chemin de Grange Basse begins, leading to a four-way junction.
(4) Head left towards the northern entrance to the hydroelectric power station. Climb following the yellow markings, which follow a wide track between woods on the left and meadows on the right. Reach the highest point in a small clearing.
(5) Continue along the curve to the left, on the almost flat track, heading north-east. Pass the hut and arrive in front of a large electrical transformer.
(6) Ignore the path branching off to the right; stay on the same track, ignoring all the subsequent paths veering off to the right. You will emerge onto a bend in the track.
(7) Head down to the right. ThePR® trail descends, initially gently, between woodland on the left and meadows on the right. As soon as it enters the forest, the gradient steepens over stony, difficult terrain. The descent ends at the banks of the Sor.
(8) Cross the river, then follow it to the left, emerging into a clearing. Walk 50 m to the right, towards the path overlooking a large culvert on the left-hand side of the track.
(9) Climb up the grassy path, follow the markings which pass in front of Plan Perdu and rejoin the wide white track you crossed earlier.
(10) Turn left and walk gently down towards the village and the D629.
(11) Turn left towards the Voûte Vauban.
