Head to Notre-Dame de Bois-Vert (above La Fare-en-Champsaur) and park in the car park above the cemetery.
(S/E) Facing the cemetery, head right towards the west. The route starts on a forest track. Keep left on the track, which climbs in two hairpin bends through the larch forest for 400 m before continuing along the hillside.
(1) After crossing the first valley, the path through the woods is fairly easy going with a few short descents. The trail comes to a halt at the ramparts of a double valley, which you will need to cross via a path carved into the detrital cliff. There are no particular difficulties, except in the event of a storm! The path then turns into a pleasant, bucolic trail. You will reach a fork at the signpost marked "Clot de Ventecul" (1,330 m).
(2) Leave the forest track that descends to the left and continue straight ahead towards the Laye station. You are now in the Bois Vert National Forest. Cross the Ruisseau du Villard at the foot of the Pic de l'Aiguille. Reach the "Les Croussières" crossroads (1,350 m).
(3) Continue downhill to the left (ignore the path that climbs to the right). You will then reach a forest road at a place called Les Chaumattes (1,320 m).
(4) Continue along the road that branches off to the left (ignore the two paths on the right that lead to the Laye resort). Staying in the forest, cross the Villard stream again.
(5) Continue along the track, ignoring the small path that descends to the right (towards an elevation of 1220 m), and continue to a new fork at Les Selliers (1180 m).
(6) Leave the path that climbs to the left and continue on the road towards the houses. Cross the Torrent des Farelles again just before the road makes a wide bend. Cross the hamlet almost to the last houses (tarmac road) and continue to the junction with the D 217a (Route du Plantier).
(7) Take the path on the left (Chemin de Bois Vert) for 900 m. You will arrive at the sanctuary of Notre-Dame de Bois-Vert (1,213 m) via the chapel. Go around the cemetery on the right-hand side before arriving at the car park (S/E).
