Starting from the square by Saint-Péray station, the start of the walk is in built-up areas; be sure to use the pedestrian crossings.
(S/E) Follow the railway line due south, towards the village of Guilherand. Pass in front of the Rémy Nodin wine cellar, then, after the Beylesse roundabout, past the greengrocer’s, go past the Fruitcoop buildings and continue southwards.
(1) About a hundred metres past the gate leading to the quays and the Fruitcoop car park, turn left between the two vineyards, following the fence of the first one, towards the railway line. At the foot of the railway embankment, head south until you reach Avenue Georges Clemenceau. Follow it to the right, then turn right again onto Avenue de Lyon. Cross at the pedestrian crossing, walk up the avenue heading north, and after about a hundred metres you’ll find the L’Arma passage on the left.
(2) Take this path, which winds through gardens and vineyards, to emerge onto Rue des Fourniers. Turn right onto the steeply ascending street and continue until you reach a cross. Turn right towards the water tower on Chemin des Gardes. The climb is quite steep but not very long. Pass a ruined barn to reach a plateau planted with vines, the Plateau des Gardes.
(3) After the last vineyard, the track becomes a path and winds along the hillside, with occasional short but steep climbs (take care in wet weather, as it can be very slippery). Always keep to the paths on the right and never return to the small tarmac road of the Val d’Enfer. After crossing a low wall with a set of steps, follow the flat path to the left which leads to the marl deposits above the Val d’Enfer. Follow a path carved into the marl to the right and join a gently ascending track leading to a section through rocky boulders.
(4) Climb over the boulders to reach a platform. Turn left onto the wide path, then take the road to the right for about a hundred metres. At the Les Enfers signpost, turn right heading due north towards the Crussol ridges. Follow theGR® 42, which climbs steeply through the holm oaks. After passing a small quarry on the left, you’ll reach a flat area facing the large quarry.
(5) Take the small path that heads off to the left then immediately turns right. The path descends into the quarry. On a short descent, turn right towards the second high platform of the quarry and head towards the far left. Pass in front of an old quarrymen’s house, of which a few remains are still visible, and keep to the paths on the right. After several ascents and descents, you’ll find yourself in front of another quarry (worth a quick look; there are also some quarrymen’s remains here).
(6) Head slightly to the left. After about 200 to 300 m, you’ll find a path leading down from the ridge. Follow it to the first hairpin bend; do not turn left but go straight on. This path winds along the hillside, sometimes ascending, sometimes descending. A little further on, you will come to a second path descending from the ridge; follow it and also head right under the holm oaks until you reach a third path descending from the ridges.
(7) Follow it to the left (caution: fairly steep descent). Walk past the Top Secret climbing site to reach a platform with a picnic table. Turn slightly right onto the path which leads to a signpost on the main trail. Turn right, walk for about 150 m, then continue left onto a wider path until you reach a hairpin bend below the Auberge de Crussol.
(8) Head left up the stairs then take the path towards Château de Beauregard. In front of the entrance to the château, turn right, walk past the château and then through the park to reach Avenue Asso. Turn right and at the roundabout, cross Avenue du 8 Mai and then the Ruisseau du Miallan.
(9) Turn right onto Quai du Docteur Bouvat towards the railway line, walk for about 300 metres and turn left to return to the station square (S/E).
