No signposts
(S/E) Opposite the cemetery, turn left onto the road, then right onto Rue des Rollands. At the fork, continue straight ahead until you reach a T-junction. Turn right onto Chemin de la Montagne, which is paved at first but becomes a dirt track after the last house. The very pleasant climb through the holm oaks leads to a fork. Go up to the left, where the path narrows. About 300 metres further on, the slope levels out and the path joins a crossroads.
(1) Pick up a path coming from the left and continue right on a slightly more open flat section. The path climbs a little more and arrives at another open area (an old woodcut) which offers some views of the surroundings. Follow the path downhill and join the D732. Cross it and continue straight ahead in the same direction.
Yellow-green markings
The path climbs again and becomes a wide trail. 50 m after the road, look for a trail that climbs steeply to the left. Leave the trail and turn left to follow this trail, which rejoins the trail 200 m higher up. Follow the trail to the left to climb up to the D732 in the Pas de Boussière bend.
(2) Follow the path that goes around the bend on the left outside the barriers. At the end of the barriers, cross the road and climb up to the right to the viewpoint to admire the landscape (Vercors, Rhône Valley, Ardèche mountains, etc.). Return to the road and follow it to the right until the next junction. Turn right onto Chemin de Marquet, towards Mourras. Pass Ferme Marquet, Ferme Mourras on your left and then the houses of Mourras on your right to reach the Mourras sign.
Yellow-green markings + blue-red markings at times
(3) Leave the paved road and turn right towards Pas du Buis on a faint track in a field (it will be more visible as you climb). Follow a hedge of trees and boxwood and, at a fork, keep right. Continue in the same direction, staying close to a fence, until you reach a gate.
(4) Turn right, go through the gate and follow the path opposite, which enters a boxwood tunnel towards Danier. The path descends gently into the forest, widens and then reaches a fork. Follow the path on the left, ignoring the path that descends to the right. Shortly afterwards, turn left onto a wider path that descends and arrives at an esplanade (Danier).
(5) Follow the path straight ahead, quickly ignoring a path that descends to the left, and continue straight ahead to arrive at an esplanade (sign for Giraudon N63 cistern). Continue in the same direction on the track that descends to the Combe Grand crossroads.
(6) Continue straight ahead on the track for about 200 metres until the next junction. Leave the track and continue left on a path that winds through the woods for over a kilometre, with occasional views of the Rhône Valley and, further on, the Château. The path opens onto a clearing.
(7) Continue straight ahead on the track towards Les Terres Blanches. Leave a path on your right and a trail on your left (not visible on the map) and continue for a few steps to reach the Les Terres Blanches crossroads.
(8) Turn left onto the path towards the castle. Shortly afterwards, at the fork, follow the left-hand path which descends slightly. At the next crossroads, continue straight ahead to climb up towards the castle.
(9) Enjoy the panoramic view of the entire valley and retrace your steps to the track.
(8) Turn left and follow the track for 400m to reach the large crossroads at Gros Chêne (wooden gate on the right).

(10) Continue straight ahead towards Chapelle Sainte-Marguerite, leaving the path on the right for the return journey. At the next crossroads, turn right and follow the path uphill to reach Chapelle Sainte-Marguerite.
(11) Turn around and take the same path back to the Gros Chêne crossroads.
(10) Turn left and descend towards Combovin. At the foot of the village, cross a ford either on concrete blocks or on the raised footbridge. Pass a landscaped area and climb back up the paved road to the Lavoir crossroads. Turn right, pass in front of the temple and return to the cemetery car park (S/E).
