Park your car near the drystone shelter at the start of Chemin de la Grange Neuve (above the village of La Roque sur Pernes on the D57).
(S/E) Start by following the road, then the path that passes in front of the Grange Neuve guest rooms and reaches a three-way junction.
(1) Turn left, walk a few metres and quickly leave the track to take the path that starts on the right. Further on, leave the GRP® on the left and continue to the hamlet of Les Barbarenques.
(2) Leave it on your right and continue almost opposite. Continue straight ahead at the next junctions, pass a pumping station and arrive at the access road to the quarries.
(3) Turn left and go down this road until you reach the next fork. Turn left and you will reach the chapel, the sanctuary, the hermitage and the Saint-Gens spring.
(4) Turn around and continue on the GR® trail, which starts at the hairpin bend, and you will reach the Miraculous Spring.
(5) Continue on the GR and climb up to the plateau at Rocher des Trois Luisants. In just a few metres, the magnificent view of Mont Ventoux gives way to an equally beautiful view of the Alpilles and Luberon.
(6) Descend from the plateau, continuing to the right at the next fork. At the fork in the track, head straight ahead and you will reach a three-way junction.
(7) Keep left and reach a fork a few metres after cistern 128.
(8) Continue to the right and follow the track that runs along a small valley on your right and join the path you took just after Grange Neuve at the start of the hike.
(1) Follow it to the left and, taking the opposite route to the one you took on the way there, reach La Borie (S/E).
