(S/E) Head towards Rochechinard on the left-hand pavement, then turn left to continue along the school (do not follow the signs for Rochechinard). Cross to the right-hand pavement and continue straight on to Avenue Léon Laurent (D76). Follow this avenue on the right.
(1) Just after a telecommunications pylon and at a pedestrian crossing, take the path between three large stones and continue over a magnificent bridge. Cross the D76 with caution and take the path opposite that climbs towards La Motte Fanjas. Return to the D76 at the entrance to the village, follow it for about 150 metres and, in front of the MC PHY factory, turn right towards the village centre.
(2) Turn right before the church and stay on this road for about 350 metres. In the bend, go down the path on the right and follow the pond below on the right. Continue along this path uphill to reach the Béchat farm. Turn left and continue along the small road that goes up to the right.
(3) Turn right after the high-voltage power lines, then take the first path on the left towards Fayolle. After 100 metres, turn left again and continue along the path until you reach the small road that leads to Les Massots (Chemin de la Fayolle).
(4) Turn right, keep right at Les Massots and continue towards the old quarry. When you reach the courtyard of a house, continue along the path that descends to the left to rejoin the Saint-Nazaire road. At the quarry, turn left onto the D209 road which climbs (caution: frequent traffic) to a place called Les Merles.
(5) Leave the road and turn right at the hairpin bend onto the wide path that climbs gently, then turn left towards Bois Savoyard. Enter the forest and climb the path, which winds around several bends before reaching a small road. Follow it to the right as it climbs.
(6) In front of a ruin, turn right onto the track that climbs, continue after the hairpin bend and pass in front of the pumping station. Enjoy the view of the Vercors, which lights up in the evening.
(7) At the bend, turn right into the woods and continue north-northwest towards La Calagne. Keep going in the same direction until you reach the crossroads at Tire-Vire.
(8) Continue straight ahead, still heading north, along the path that descends towards Saint-Nazaire. Be careful on a few steep sections before arriving at a small road.
(9) Turn right for about 30 metres, then turn left down Chemin de Cachenoix.
Continue downhill to the village, enjoying magnificent views of the Bourne and the aqueduct.
(10) Once you reach the village after a pleasant descent, turn right onto Rue du Bourg Souverain. Pass in front of the church as you descend, then turn left onto Rue Julie Chamat to return to the town hall car park (S/E).
