From the D9 between Devesset and Saint-Agrève, at the lake access point, known as La Chaumette, park on the opposite side of the lake.
(S/E) The route starts by taking theGR®430north-east, downhill.
(1) After 300 metres, leave theGR® at a clearing and take an unmarked path on the left. This path is a little difficult to find, as it is not maintained and has some branches across it. Look out for the left turn after 150 metres.
(2) Cross a small stream. Continue to La Coste, inhabited all year round, and find a tarmac road. Turn right onto the road.
(3) Continue straight ahead on the road for 300 metres until you reach a place called Les Layses and take the wide forest path that climbs to the left.
(4) At the crossroads at the top of the hill, go down the path opposite, slightly to the left, to reach a gravel path. Take it to the left and follow it for 1 km to the end, at La Valette.
(5) The gravel path becomes a trail again. Follow it slightly uphill for 100 metres to reach a crossroads.
(6) Take the path furthest to the right, which descends steeply and is marked in white and yellow. This is a very pretty path to Bruas, where a signpost overlooking the road indicates that you are joining the GR®.
(7) Turn left. The path passes above the houses, then descends towards the bottom of the valley before climbing again towards Le Portier and the highest point (871 metres), where you can see Rochepaule.
(8) A cross, a bench in the shade, the entrance to the "Repaire du Lézard": this is a good place to take 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. After 300 metres (altitude 842), turn left towards Coméat. Then turn right towards La Grangeasse, a proud building that can be seen in the distance but loses its splendour when you get closer.
(9) At the end of the buildings, the path is blocked by scrub for about 50 metres. Go around this obstacle by walking along the edge of the field above, and rejoin the path immediately below where the passage is very clear. Follow it to the road at a place called Les Grangettes, a house with a water source.
(10) Take the road on the left towards the south for 500 metres, until you reach the D214 which comes down from Rochepaule. Turn right and pass in front of a Ukrainian "holiday camp" just before the bridge.
(11) Cross the road bridge. Turn right onto the road. Stay on the departmental road for about 1 km.
(12) Take the wide path on the right, crossing the stream. The path is marked in white and yellow for 1.2km until you reach a crossroads marked with a signpost.
Turn left uphill towards Devesset. Do not cross the Aygueneyre. The signpost is marked La Rouveure, which is actually only 500m further on. Follow the path, which is again theGR®, and return to the intersection you passed on the way out.
(1) Take the same route back as on the way there to the car park (S/E).
