Departure from the car park on Place René Cassin: hiking information sign.
(S/E) Cross the RN104, take the street opposite for a few metres. At the first intersection, turn left and go up the alley and its stairs to the junction with Rue du 06 Juin 1944. Turn left, walk past the church, continue on this road to the next junction. Take the road on the right, following it and ignoring the other roads leading to housing estates and farmhouses.
At the end of this road, take the dirt track opposite. Walk along the bottom of Château de Cheylus until you reach the road and the Plot mast, turn right onto Route de Pansier, towards Le Pigeonnier, and follow it to the bridge. Cross the bridge and continue along this small road alongside the stream. At the Agau mast, follow the signs for Le Pigeonnier.
(1) At the first bend, leave the Pansier road and take the track opposite. Shortly after a large scree slope on the right, take a small path on the right, which shortens a bend in the forest track. After rejoining it, follow it to the right towards the hamlet of Grand Maleval.
(2) At this junction, turn right onto the main track leading up to the Pigeonnier farm. Stay on this track, marked with yellow and whitePR® signs, ignoring the various paths branching off to the right or left. Ignore the blue signs, which are for motorised vehicles. You will see the Pigeonnier farm: the track passes below it. Continue to the Pigeonnier mast.
(3) Follow the track to the left towards Serre de Gruas. At the next junction, continue straight ahead. After about 250 metres, take the track going up to the left. At the next crossroads, you will reach the Pertusol mast.
(4) Follow the track straight ahead towards Croix de Gruas. Stay on this track until the next junction.
(5) At the Serre du Pré mast, take the track on the left towards Croix de Gruas until you reach the three-way junction.
(6) Turn right and follow the track for about 50 metres until you reach the road and the Croix de Gruas mast. Go up the small road on the right until you reach the hamlet of Gruas.
(7) Continue along the ridge, heading north-east (you can also climb up to the pylon, the highest point of Serre de Gruas).
(8) At the Goulet de la Verrière mast, take the track on the right towards Saint-Cierge-la-Serre.
(9) Reach the Col de la Croix. Descend southwards, taking the track on the right, towards Aurelle. Further down, at the road, walk alongside the hamlet of Vignal. Continue along this small road.
(10) At the Aurelle mast, turn left, pass under the houses, and continue on the small road leading to the hamlet of Les Michaux. Cross the hamlet and continue south-southwest to the bridge over the Vendèze stream. Cross it, take and stay on this track (following the signs for "Le Pigeonnier") until you reach the next three-way junction.
(11) Turn right, heading west. Continue along this track until you reach the next crossroads.
(12) At this crossroads, turn left for about 700 metres until you reach another junction, then turn left: you will find yourself back on the track you took on the way there. Continue straight ahead until you reach the Pigeonnier mast.
(3) Turn left towards Flaviac; the track begins its descent through the woods.
(13) At a hairpin bend, turn right and continue along the track.
(14) Shortly before La Grange, turn right onto a narrow, very stony path (sign: Flaviac piétons). Descend through juniper trees and woods along this stony path, which in places overlooks and runs alongside a track but never joins it.
(15) At the Vialettes mast, turn left onto a path that quickly joins a small road. Follow it for about 400 metres. You will reach the Zayette mast.
(16) Then turn right and continue south. Turn right again onto the Chemin de la Montée de Flossac. At the end, turn left onto Rue de Rias, then right. Continue to the RD104, cross it and reach Place René Cassin (S/E).
