(S/E) From the small Viarrands car park, located above the Chèvre Verte lodge, head south-east and follow the path uphill towards the Croix de Roussieux for about 200 metres.
(1) At the Auches crossroads, turn right and follow theGR®91trail up to the Col de Corbières.
(2) Col de Corbières signpost: for the return trip, take the yellow-marked trail on the right, which climbs to the summit of La Vanige. Follow the markings carefully, as the climb to the summit is very steep but not particularly difficult.
(3) The descent is via the same route*.
(2) From the Corbières mast, take the yellow-marked path heading south-east, leading to the Col de Haute-Huche and Croix de Roussieux. Stay on this path, which climbs to the Clavelière ridge.
(4) At the Col de Haute-Huche mast, continue along the ridge path on the left, leading to Croix de Roussieux.
(5) At Croix Roussieux, descend through the woods, taking the yellow-marked path on the left (former route 97, which runs concurrently with 98). Stay on this marked path, which will cross a track further down.
(6) Follow it to the right for a few metres, then take the path continuing to the left.
(7) Reach the Sous le Rocher Blanc mast. Turn left and continue along this track marked in yellow and 97, keeping westwards. There will then be a series of descents over approximately 2.5 km, followed by a fairly steep but short climb and an easy passage over a collapsed ravine to the hamlet of Les Turcs.
(8) At the Turcs mast, continue slightly to the left along the track passing under the hamlet. The route is no longer marked, so follow this track to the Auches crossroads.
(1) Continue straight ahead and take the same path you took on the way there to reach the Viarrands car park (S/E).
