Park in front of the Monastery of Saint-Paul de Mausole.
GR Trail (White-Red) /PR (Yellow)
(S) Opposite the entrance to Saint-Paul de Mausole, take the Chemin des carrières on the right. Go alongside the outer wall of the monastery.
PR Trail (Yellow)
Take the first path on the right which leads to the valley of Saint-Clerg (1) . Up to the top of the valley, the circular walk will be signposted by the botanical trail waymarkers. First, go alongside a small olive grove and then past some old stone quarries (below).
After a hairpin bend, ignore the small path to the left. Go through the gate. On your right, you will see the wire fence of the Ancient site of Glanum (2) .
You are in the relatively shaded valley of Saint-Clerg, which is appreciated in hot weather. Ignore a path climbing gently to the left. Go through a small rocky gorge and pass by the nearby ruins of a chapel. Ignore two paths which leave to the left. After a sharp bend and a good climb, you will join a small tarmacked path which leads to the Caume plateau (3).
Don't take the route, instead take the path immediately on your left which slopes steeply. Ignore the two footpaths on your right and continue up to the top of this hill, where you will see a cairn.
From this 360° panoramic viewpoint (the view we've been aiming for), you will see: "Le Rocher des Deux Trous" down below. Go down the steep and rocky slope towards the rocky outcrop (the two holes are not visible at this level). You will meet a path. Continue straight on to go around the rock and admire the two holes formed by erosion. You can take some beautiful photos through these natural orifices.
Return to the track which we then take due south. It leads to the tarmacked route which we left earlier. Don't re-join this route, but instead continue onwards, taking the path on the left. It ends at the intersection of the route and a track which goes downhill (4).
GR6 Trail (White-Red)
Take the track on the left (Gaudre de Valrugues). After going downhill for a good distance in zigzags (the valley goes downhill steadily), cross through a small rocky gorge. At this point, the track is quite rutted as a result of torrential rain a few years ago. The track has never been restored.
Go through a gate (5), ignore the track crossing our route which descends straight on, alongside the properties. You will reach a crossroads of the waymarked paths (6).
GR 653D Trail (White-Red) / PR (Yellow)
Take the trail to the left, ignoring the other two paths on the left. Further on, the path is bordered on the left by low stone walls and shaded by magnificent oak trees, go through the two wooden gates.
At the small tarmacked path (7), take the right. Staying on it, it leads directly back to your point of departure by re-joining a section of the path we followed on the outward journey (1).
