Go straight across the roundabout and follow Rue de Marcale, which veers slightly to the right. After 50 metres, turn left and follow the path uphill (signposted "voie sans issue" [dead end]). After 100 metres, look for a gate on the right with two lions above it. Continue for another 20 metres and leave the path to take a trail on the left that starts at the corner of another gate. Join the road at the entrance to the Château de Beauregard.
(1) Turn right and follow the road uphill (tarmac), then quickly leave it and turn right onto a beautiful paved path. 250m further up, pass several flights of steps to come back onto a small road. Turn left towards the car park and quickly turn right onto the track that runs alongside the car park.
(2) You will arrive at a building and the Verdure theatre. Go around the building on the left and follow the steps on the right that lead up to an esplanade. Continue climbing on the left, following the path again. 20 m further on, continue left towards Soyons. Enter the ruins of La Villette through an old fortified gate. At a crossroads at the foot of a solitary tree, turn right and stay on the main marked path to reach the ruins of Crussol Castle. It is possible to visit the ruins, but be careful of the unsecured areas at the edge of the cliffs.
(3) Follow the path that climbs southwards along the ridges, sometimes through holm oak woods or in open country offering beautiful views of the Rhône Valley.
(4) At the Chardancet signpost, continue in the same direction towards Soyons along the ridge, leaving the path that descends to the right and leads to the Théâtre de Verdure. 500m further on, at the Ployes le haut signpost, continue in the same direction.
(5) When you reach the Les Écoles signpost, continue in the same direction, leaving the path on your right. About 200 metres further on, turn left at a crossroads and continue on the path that passes just below the ridges.
Pass the old quarries, ignore a path on the right that descends and continue straight ahead on the stony path. Begin the descent, then after a left-hand bend, follow a vineyard to reach a paved road at the Les Enfers signpost.
(6) Turn right onto this road towards Soyons.
Yellow and white signposts

Cross a footbridge and continue straight ahead on the path. Go under the D533, pass a footbridge that crosses the Mialan on the right and continue straight ahead. 20 metres further on, the path turns sharply left, crosses Place Henri Richard and joins Rue Ferdinand Malet.
