Departure: north exit of the village of Parnans before the bridge over the Joyeuse.
(S/E) When leaving the car park, take the D123 on the right. Turn onto the first road on the left, Chemin Pré-du-Mulet.
(1) At the bend, continue straight ahead on a path. Stay on the same bank of the Joyeuse.
At the fork, go up a path on the right along an orchard, then into the woods. At the top, turn left and continue on the tarmac road to reach the hamlet of Replat.
(2) Take Chemin du Replat on the left. Pass the Bois Burais crossroads and reach the D123.
(3) Follow it to the left for a few metres, then turn right onto a dirt track. It descends into a valley. Continue along a track and rejoin the tarmac road at a house. Walk along the road for 250 metres until you reach a crossroads with a track.
(4) Turn left, taking a hairpin bend, onto Chemin Charaire and climb through meadows and woods.
(5) At the junction with the path leading to Buis Jaquet, continue along a small road until you reach the T-junction at Les Fenêtres (panoramic view).
(6) Turn right (GRP®Tour de Pays de Saint-Marcellin) onto the ridge road at the border between the Drôme and Isère departments. At the crossroads, climb straight up the Route des Crêtes, which leads to the orientation table.
Continue along the road on the plateau until you reach Bel-Air.
(7) Turn right onto Chemin de la Mine-d'Or, leaving the GRP®. Further on, continue along the dirt track, walk alongside a long livestock building and keep going downhill. You will come out onto a road in the hamlet of La Maladière.
(8) Turn left and then immediately right onto Chemin de la Maladière: the small road leads to the D123. Turn left to return to the Parnans car park (S/E).
