Crêtes de Chamouse (N°1)

This route along the border between the Drôme and Hautes-Alpes departments offers panoramic views from the ridge! The vast expanse of mountain pastures is breathtaking. Not to be missed!


At the signpost, take the trail that descends to the left. At the intersection near the ruins, turn right and pass the “DFCI – Tussie Reserve” sign. At the next fork, turn right, follow the winding trail uphill, and cross a small stream. Continue up the trail until you reach a meadow. Continue straight ahead to reach a small path that runs alongside a fence. Follow this path and, further on, at the intersection, go straight ahead; you can also climb directly up to the ridge on the right. Cross a small dry stream and then a marl area. Then climb to the Col de Tous les Vents, preceded by a short stretch through the forest.
At the pass, continue along the trail to the right, then cross a national forest by taking a wide trail to the right.
At the next intersection, turn right and head uphill to reach the Col d’Izon (1,343 m).
At the Col d’Izon, turn right toward “Montagne de Chamouse – 1.5 km.” Follow the markers leading to the vast Chamouse mountain pastures. Cross the pastures to the summit of Chamouse (1,532 m). There is no longer a trail on this section of the route; follow the cairns. Descend 900 m along the ridge.
At the signpost, turn right onto a small path descending into the forest (“La Tussie” - 1,430 m) toward “Laborel.” Cross the beech forest and continue descending. Further down, the path becomes a trail. Follow this trail back to the starting point.
