Departure from Pont de Villard on the road between L'Enclus and Le Forest. Head towards Pré Grand and park after the building.
(S/E) Head south on the Route Forestière du Bois Rond to the Fontaine d'Hurtillier.
In June 2025, the water flowing from the fountain is announced as non-potable.
(1) Take the wide path that climbs up to the left through the woods (trail/mountain bike markings) and continue through the forest. Join the forest road.
(2) Turn left (GR® de Pays Tour du Dévoluy trail markers) towards Jas de Barges and Col de Rabou. Exit the woods and continue along the path. Find the start of the trail at three trees and a cairn on the left, without reaching Jas de Barge (sheepfold).
(3) Leave the GRP®. Take the well-marked path on the left. It is often used by mountain bikers. Cairns and bike markings replace the coloured markings. You will easily reach the Cascade de la Souloise waterfall.
(4) Continue along the obvious path that descends through the forest.
(5) Cross the stream for the first time, continue along the marked path and cross the river again to reach the first road you took, a few dozen metres from your car (S/E).
