Departure from the car park at the foot of the Cirque d'Archiane.
(S/E) Reach and cross the hamlet of Archiane.
(1) Head towards theGR®93(Chemin des Grands Espaces). The shaded trail climbs gently at the start in "la Combe de l'Aubaise".
(2) Ignore the path on the left that leads to a waterfall and continue climbing up the valley.
(3) Ignore the Cirque d'Archiane discovery trail on the right and continue the climb, which becomes steeper. Towards the end of the climb, a sign warns us not to linger under the rocky outcrop due to the risk of falling rocks! Here, we enter a rocky environment and walk over a series of long scree slopes.
(4) At the Carrefour des 4 chemins de l'Aubaise, where there is a large cairn, take the path that climbs left into the scree to finally reach the plateau.
(5). Turn around to enjoy the magnificent view of the gorge we have just passed through. Continue on theGR®93, crossing the "Plaine du Roi" where large slabs of rock provide a place to rest. Be careful of the sharp limestone pavement, however!
(6) At the 4 Chemins de la Ville fork, leave theGR®91on your left, which leads to Chatillon-en-Diois, and continue north. Magnificent panorama of Mont Aiguille and Grand Veymont on your left.
(7) After about 700 m, leave the path on the right that leads to the Bergerie du Jas Neuf.
(8) After about 600 m, leave theGR®93, which heads towards Pré Peyret, and follow the valley climbing to the left, which will take you to the sheepfold and its fountain, then to the Col des Hollowed-Out Tree Trunks Serving as Drinking Troughs.
(9) Continue climbing to the right up Montagne de la Ville.
(10) Enjoy the magnificent view over the Drôme valley and the 3 peaks. Return to Col des Hollowed-Out Tree Trunks Serving as Drinking Troughs.
(9) From the Col des Hollowed-out Tree Trunks Serving as Drinking Troughs, the return journey is via a little-used south-east facing path, which you follow either by azimuth or by cairns, to find the ruins of Jasse de la Ville at the bottom of a small valley.
(11). Then rejoin theGR®51and follow it north-east until you reach the junction with theGR®93.
(6) Take the same route back to the junction with the Sentier Découverte.
(3) Take the Cirque d'Archiane Discovery Trail and its information boards on the left. Then descend to the hamlet of Archiane and return to the car park (S/E).
