Park at the top of Chemin du Coulet.
(S/E) Take the path that descends to the right. Ignore the path at the bottom of the valley and turn left to climb up opposite. When you see the vineyards, follow the path that runs alongside them towards the buildings of the La Verrerie estate.
(1) A few metres before the corner of the vineyard, leave the road and follow a path through the woods between the La Verrerie estate and the houses to reach the entrance to the château. Then take the road (closed to all vehicles) that climbs to the left.
(2) Leave the "La Verrerie" signposts and follow the path on the left, pass the first hairpin bend, then continue straight ahead uphill.
(3) At the junction with a wider track, continue climbing to the left. You will immediately find a pretty little cave on the right-hand side of the path. Continue climbing the path, pass the first hairpin bend immediately after a fire hydrant and continue for about 400 metres.
(4) At the next sharp left-hand bend, leave the path and take a small, unmarked trail that climbs up into the valley to join theGRP® Autour du Luberon further up.
(Note that it is also possible to continue along the path for 800 m and then turn right onto theGRP®.)
(5) Follow theGRP® on the right to reach the Aire de Bosse. Then take the marked path that climbs towards the cedar forest and Les Portalas.
(6) From Les Portalas, continue along the ridges. You will pass a fire cistern and shortly afterwards arrive at a panoramic view of the south with an orientation table. Continue along the ridge for about 40 m.
(7) A path, which is not very well marked but indicated by a small cairn, leads down to the arch via a slightly technical passage. You will reach the arch after about 200 m.
Pass under the arch to continue on a very steep path that descends southwards through the undergrowth and sometimes over scree to join a track at the bottom of the valley.
(8) Descend the track towards the west. After 1.5 km, you will come across signs indicating the climb to the ridges via the Vallon de l'Arc (trail closed from 1 March to 15 September to protect birds of prey).
Continue down the track to reach the Tapi crossroads.
(9) Take the path on the right (GRP® Autour du Luberon), towards Les Borrys and La Raveyrolle.
(10) Continue along the path (GRP®) ascending to the right, still towards Les Borrys. After 650 m, when you reach the plateau, continue to follow theGRP®, which leaves the track to follow a path on the left (cairn). You will rejoin the track further down. Descend for about 450 m.
(11) Just as you leave the wooded area, take a path on the left above the orchards. At the end of the orchards, after passing some beehives, continue along a path through the undergrowth towards the east.
(12) At the edge of the woods, follow the path southwards to rejoin the Chemin des Huguenots on the left, which will take you back to your starting point (S/E).
