From Bédoin, head towards Chalet Reynard on the D974 and join the Melettes car park at the side of the road 12 km further up.
Red and white markings for theGR®91B
(S/E) From the car park, at the Jas de Melette marker, cross the D974 and take the forest path towards Barragne. On the right are the ruins of Jas des Melettes.
Continue to a crossroads. Ignore the paths to the right and left and continue straight ahead on the path that descends to rejoin the track (the route on the map does not correspond to the markings on the ground).
Turn left and continue along the flat path to Jas du Roussas. Continue straight ahead towards Le Roussas, ignoring the path that goes up and down. Go down a small valley to find the Le Roussas signpost.
Yellow markings
(1) Leave theGR® on your left and head right for a few metres, then turn left towards Combe de la Grave. The small path climbs steeply, then continues along the mountainside before plunging back into the valley.
(2) At the crossroads, turn right and a few metres further on you will find another crossroads with the Combe de la Grave signpost. Take the left-hand path towards Jas de Couanche. 200 metres higher up, the path veers left to climb towards the cliff and then continues on to the ruins of Jas des Compagnons.
(3) Then turn right, heading north, to climb steeply. Next, the path veers west to descend towards Jas de la Couanche and its vast esplanade.
Red and white markings
(4) Turn right towards Combe Fiole Sud on the path that runs alongside the Jas and enters the forest. 200 metres further on, the markings leave the path and turn right to join a track at the Combe Fiole Sud signpost.
Turn right for a few metres until you reach the bend.
Yellow markings
(5) Leave the track and turn right onto the path that climbs up Combe de Fiole. Stay on the main path that climbs up the valley, ignoring the two paths on the left (which are not very visible on the ground). Very soon, ruins appear on the right and left of the path; these are the remains of ice houses.
Continue climbing, which is quite steep in places, passing the Rocher de l'Aiguille on your right.
Almost at the top of the valley, a cairn marks a path on the left (the route on the map does not correspond to the markings on the ground). Leave the path on the left and continue straight ahead until you reach a track at the Petit Pierre marker.
Turn left onto the track towards Jas des Pélerins. 200 metres further on, pass two cairns on your left and leave the track to climb up to the right on a path that joins the Jas des Pélerins marker planted higher up.
(6) Turn right towards La Fréchière to find Jas des Pélerins 100 metres higher up.
Ignore the yellow markings that leave to the left of Jas and follow the ones on the right that pass in front of Jas. Continue along this path on the mountainside, which cuts across a trail climbing up the valley and continues through scree and forest. After passing several small valleys, the path climbs again to get closer to the road.
(7) Just before reaching the road, the markings veer to the right. The trail on the ground is almost invisible, so you will need to look out for a few posts with markings on them and a few cairns. This is the most difficult part of the route.
The markings descend, return to a wooded section and then reach the bottom of a valley at the Jas de la Fréchière ruins. Turn right at a right angle to descend the valley and join a track at the La Fréchière marker.
(8) Continue straight down the valley on the path towards La Grave for about one kilometre.
(9) At the La Grave crossroads, take the path on the right that enters the Combe de la Grave for 1.7km.
Pass the Combe de la Grave signpost and continue straight ahead towards Le Roussas for a few metres to return to the junction you took on the way there.
(2) Leave the path, turn left under the trees and climb up the rocks to exit the valley. Cross the forest and descend into another valley. Turn right at the cairn and find the Le Roussas signpost.
(1) Turn left onto the path that climbs up to Jas de Roussas. Continue straight ahead, ignoring the paths on the right and left. 300 metres further on, the signpost directs you to turn right onto a path that climbs steeply to rejoin the track. Continue straight ahead on the path that leads back to the car park (S/E).
