Park near the church of Saint Barthélemy de Vals.
(S) From the car park, take Rue du Vercors towards Saint Vallier.
(1) At the intersection with the D500, turn left towards the dancing rocks.
From there, follow the large yellow and red loop trail around the hills.
Continue on the D500. A few metres before the sign indicating the end of the village, take the paved road that climbs up to the left.
At the end of the road, take the well-marked grassy path (yellow and red) between the two houses.
(2) At this point, leave the path on the left and continue straight ahead (there is a faint yellow-red mark on a tree on the left).
(3) When you reach a farm, cross the road and continue straight ahead along the path. Follow it down to the tarmac road and turn right. Follow this road for about 50 metres.
(4) After the house, turn left onto Route des Landières, which continues as a carriageway. You are still following the yellow-red markings.
The path leads to a road near a farm. Continue straight ahead on the road that climbs uphill. Do not take the yellow-marked path that branches off to the left towards a recent house on the right. Continue on the tarmac road.
(5) Then, just before a road that branches off to the left, leave the road and take a path that descends to the right. The yellow-red mark is painted on a rock at the foot of a sign prohibiting access to the orchard.
Go down this path, cross a small stream and then go over a small wooden bridge to reach the signpost for Les Fosses.
(6) When you reach the Les Fosses signpost, leave the Grande Boucle des Collines circuit and follow the
to head towards the Riverolles stream, following a path marked in yellow.
After about 400 metres, the path joins the Riverolles stream. Turn right and follow the stream without crossing it, keeping it on your left and ignoring any other paths, even those that are marked. In spring, seasonal flowers carpet the undergrowth and the edges of the path.
(7) After about 1.2 km, you will arrive at the Croix de Romans, a small wooden cross on the left before a stone bridge. Cross this bridge and turn right onto the paved road.
(8) On this road, the Route des Roches, just after the Saint Barthélemy de Vals 3 km milestone, take the dirt track on the left. Follow it for about 100 metres, then leave it on the left and take a grassy path that runs alongside a fence and leads to a track suitable for vehicles.
Climb this path, which runs alongside a sand quarry, to rejoin the Route des Roches and follow it to the top.
(9) The destination of the hike is there: the dancing rocks. Turn right onto the Traversée des Roches path. Explore the site at your leisure.
Once you have finished, continue along the Traversée des Roches path to reach the farm at the waypoint (3) and return by retracing your steps along the same path you took on the way there (E).
