Depart from Barbières, cross the village towards the Col de Tourniol and park at the exit after passing the Pertuis (narrow passage between two cliffs). Small car park on the left.
(S/E) Pass through Le Pertuis towards the village of Barbières (climbing site on the left, cave on the right) and immediately turn left onto Route des Chovets (signposted, yellow/red markings forthe GR® de Pays du Tour des Monts du Matin). About 350 m further on, look out for the passage on the left between a wall and a house (fire hydrant).
(1) Turn left (if you miss this passage, take thefirst road on the left, which joins the route). The path goes around a property and joins the road (Chemin de la Garde). Continue straight ahead following the yellow/red markings, ignoring a road on the left leading to a property. The road becomes a path, climbs, and after a good kilometre reaches a good track at a small pass (signpost for Chemin des Buissonnats), turn left towards Le Soufflot (yellow and yellow/red markings).
(2) Continue along the track, following the yellow and yellow/red markings (there are several other unmarked tracks and paths). Continue until you reach a ford.
(3) There are two options for crossing the ford:
- either continue along the trail that goes around Les Baumettes (GR® de Pays),
- or take a more adventurous shortcut (marked on the map) (poorly maintained path, more stony, some brambles, slightly steeper, unmarked...). Then turn immediately left after the ford, continue roughly straight ahead, ignore a path on the left after 200 m, and about 400 m further on, zigzag from one path to another (left, right, left) to reach the Col de Côteplane and find theGR® de Pays markings again.
(4) From the Col de Côteplane, follow the yellow/redGR® de Pays markings for more than 2 km (passing the directional signs for "Champ des Pins" and "Le Soufflot des Crapaudes"). At the second signpost for "Le Soufflot des Crapaudes" (the signposts are about 50 metres apart), take the path opposite (south-east) which leads to the shoulder.
(5) From this point onwards, there are no more yellow/red markings, only a few old yellow markings that have faded over time, and occasionally some red arrows. This is where the steep climb to Pas de Saint-Vincent begins. The path, which is fairly well marked, follows the shoulder and then veers further south after a climb of about 100 metres, still following the shoulder. After about 50 metres, the path turns left onto the northern slope (a small, misleading path starts a few metres below, so be careful and do not turn left until you have spotted a large yellow mark and a red arrow on the trees).
(6) The path then runs along the rocks, and after about 150 metres, watch out for two cairns indicating the passage between the rocks, then turn right.
(7) The passage is not difficult, but it can be slippery! Be careful not to fall several metres. The path, which is not always easy to spot, climbs back up the shoulder (look carefully for the old yellow markings and any cairns!), and finally levels out to reach the rock chaos of the Pas de Saint-Vincent. At the junction with the path coming from the village of Saint-Vincent on the right, continue straight ahead and after a final climb, you will emerge at Pas de Saint-Vincent.
(8) From the pass, cross the pastures heading east, following the cliffs (with caution), the visible sections of the path, and sometimes weaving between the box trees. Reach the Sommet Pierre Chauve (cross), where the view of the cliffs and the Vercors is exceptional.
(9) Retrace your steps to the passage in the fence between the shrubs and box trees. Continue downhill through the pastures, gradually moving away from the cliffs along the fence. Reach a small shoulder and a large, clearly visible cairn.
(10) Turn left at the cairn and follow the fence, which heads south towards a large pasture clearly visible below. When you reach the pasture, cross it or continue along the fence (pass it so that it is on your right and you will soon find a well-marked path) heading east (respect the herds and keep dogs on a leash).
Head towards the ruins of Le Ronzier and shortly afterwards you will come to a crossroads.
(11) Turn left and then, a few metres further on, turn left again (pass between two fence posts). The very pleasant path completes the circuit around Pierre Chauve, gradually turning north-east. After 400 m, ignore a wide path on the right. After another 300 m, when the path turns right and then forks, take the left-hand path (the right-hand path joins the road prematurely at a hairpin bend). Reach the Col de Tourniol.
(12) Pass the pass heading north, and shortly after the memorial to the 1989 plane crash, take the path on the left. This well-marked path (a few orange horse riding route markers) crosses the D101 road several times (be careful). After 1 km of descent, you will arrive at the signpost for "La Grande Côte". Continue along the path towards Barbières.
(13) From this point, the path is marked in yellow, and the markings should be followed to Barbières. Sometimes on the north side, sometimes on the shoulder, the path joins the road at La Liore (signpost, small enclosure). Cross the D101 (take care) and find a path veering to the left until you reach another signpost a few metres away marked "Chemin de Cany".
(14) Then turn right. Continue to follow the yellow markings and ignore any unmarked paths. After about 1 km, you will come to a picturesque staircase. 400 m further on, you will reach the Route du Col (below the D101).
(15) At the signpost for "La Muletière", turn left towards "Camping Gallo-Romain" "Barbières". Go past the first hairpin bend and follow the road for about 250 m, then take the path that is not very visible in a field and starting at the second hairpin bend, heading north. Walk along a hedge on your right for 300 m (the path passes on the other side of the hedge, but is quite difficult to follow due to fallen trees and branches). Find the well-marked path at the end of the hedge, which turns left and descends towards the Ruisseau des Marais stream. Cross the stream (ford without removing your shoes) and walk along the left side of a house to reach the Gallo-Roman Campsite and the D101 road.
(16) Turn left onto the road and return to the car park where you started (S/E).
) You have to stay close to the box trees, as far away from the cliffs as possible.
