From the D9 between Devesset and Saint-Agrève, near the lake access point at a place called La Chaumette, park on the opposite side of the road, away from the lake.
(S/E) The route starts by following theGR®®430north-eastwards, downhill.
(1) After 300m, leave theGR®® at a clearing and turn left onto an unmarked path. This path is now easier to find following timber extraction work. Make sure you spot the left-hand bend after 150m.
(2) Cross a small stream. Continue to La Coste, which is inhabited all year round, and follow a tarmac road. Turn right onto the road.
(3) Carry on straight along the road for 300 metres to the hamlet known as Les Layses, then take the wide forest track that climbs to the left.
(4) At the crossroads at the top of the hill, head back down the path opposite, slightly to the left, until you reach a stony track. Take this to the left and follow it for 1 km to the end, at La Valette.
(5) The gravel track becomes a footpath again. Follow it, climbing slightly for 100 metres, until you reach a crossroads.
(6) Take the path furthest to the right, which descends steeply and is marked white and yellow. A very pleasant path leads to Bruas, where a signpost overlooking the road indicates that you are joining theGR®®.
(7) Turn left. The path passes above the houses, then descends towards the bottom of the valley before climbing again towards Le Portier and on to the highest point (871 metres), from where you can see Rochepaule.
(8) A cross, a bench in the shade, the entrance to a farm: this is a good spot for a break before heading back down.
Set off again, turning right towards the south-west along a pretty path that is quite narrow at the start, until you reach Les Grangettes. I have omitted the detour via La Grangeasse where the path has disappeared.
(9) A place known as Les Grangettes: a house with a water point that was dry in September 2026.
(9) Take the road on the left heading south for 500 metres, until you reach the D214 coming down from Rochepaule. Turn right; you’ll pass a Ukrainian ‘holiday camp’ just before the bridge.
(10) Cross the road bridge. Turn right onto the road. Stay on the departmental road for about 1 km.
(11) Take the wide track on the right, crossing the stream. The track is marked in white and yellow for 1.2 km until you reach a crossroads marked by a signpost.
Turn left uphill, towards Devesset. Do not cross the Aygueneyre. The signpost indicates ‘La Rouveure’, which is actually only 500 metres further on. Follow the path, which is once again theGR®®, to the junction you passed on the way there.
(1) Follow the route back in the opposite direction to the car park (S/E).
