To reach the starting point most comfortably, head down to the valley floor to the hamlet of Villard de l’Enclus; immediately after the bridge, turn right and follow the road for about 2.5 km towards the Bure cable car station (car park). Climb the short, steep tarmac slope to join the GR® path, which you follow to the left to enter the woods and reach the Cabane de l’Avalanche
Alternatively, at the Villard bridge, turn left onto the Route Forestière du Bois Rond (a forest track suitable for vehicles) to reach a car park near the Cabane de l’Avalanche. Beyond this point, vehicles are not permitted.
(S/E) Join the GRP® Tour du Dévoluy (red and yellow markings), which climbs gently along a track heading east-southeast towards the Col de Rabou.
(1) At an elevation of 1619, below the Vallon Froid, leave the GRP® and take a forest track on the right marked in yellow.
(2) Just after emerging from the woods, take the left-hand branch (the path seems to want to go straight on!). A few hairpin bends, amongst the blueberries, above the Bois Rond, will lead you to the shepherd’s hut and the entrance to the Vallon d’Âne (a good spot for a break or a picnic).
(3) Head down towards the sheep troughs near the hut; they are clearly visible. Then take the path on the right, marked in yellow.
(4) Just before the sheepfold, stay on the right-hand branch to enter the north-facing valley. The path is well marked and visible; a few hairpin bends in the lower section will take you to the Cabane de l’Avalanche. From there, head back to the car park (S/E).
