Head for a small bridge 500 metres south of Pradelle, where there is a small car park.
(S/E) Continue on the D135 south-west then south for 500 metres and reach the Maison Forestière des Raux (forest house) (fountain on the right-hand side of the road).
(1) 100 metres after the forest house, turn left and take the Chemin Forestier des Raux marked in yellow. The track climbs gradually (the first two paths marked on the right on the map are not visible on the ground). Make two turns and reach the first fork.
(2) Turn right onto the track (ignore the path that continues straight ahead). Follow a few hairpin bends, then the path levels out and arrives at a large platform at Col de la Bâtie.
(3) Continue straight ahead until you reach a half-erased sign marking the start of a path (ignore the path that continues uphill to the right). Follow this trail down through the undergrowth. When you reach a ruin (La Bâtie), cross a dry stream and continue down the path until you quickly reach a field.
(4) Follow the edge of the field to the left along the hedge. The trail is not very visible, but the hedge serves as a landmark. At the bottom corner of the field, follow the access path that leads close to La Brette. Turn left to reach the ford.
(5) Leave dry land and turn left into La Brette to begin your walk in the water. You can't go wrong, just follow the river.
(6) When the river makes a wide bend (Serre Pointu on the map), you are at the most beautiful spot on the route. Large boulders have broken away from the cliff and formed large pools of water that are perfect for swimming. You can get around the large boulders by following the paths on the left. Continue down the river. At times, you can walk along the riverbank or on sections of the path that go around certain obstacles. Further on, a beaver dam blocks the way (June 2017), but a path on the right allows you to go around it without disturbing the beaver family. Reach the mouth of the two rivers just before a bridge on the right.
(7) Continue to the left and walk up the Roanne. After three wide bends in the gorges, the landscape opens up a little more onto the valley and you arrive at the starting bridge. Cross the bridge and turn immediately left after the pillar to go back up to the car park (S/E).
