Parking above the hamlet of Les Borrys, under large pine trees, on the edge of Chemin du Degoutaou.
Orange markings
(S/E) With your back to the rubbish bins, turn right onto Chemin du Degoutaou, then left a few metres further on. Continue along this wide path which climbs gently through olive groves. After the last house, ignore the two tracks on the right and continue straight on until you reach the signpost for "La Reveyrolle".
Red-white markings
Leave theGR®97on your left and continue for another 50 metres on the same path.
(1) Leave the track and take a path on the right that leads into the boxwood and holm oak trees. When the wood becomes less dense, the markings join two paths coming from the right (only one shown on the map) and reach a track.
Red-white + orange markings
(2) Continue right on this flat track and leave a path on the right just before a bend. The track then slopes northwards and descends for a few hundred metres before joining another track. Continue in the same direction and you will reach the crossroads of "La Tapi" and its disused house.
Orange markings
(3) Take the path on the left towards "Vallon de la Tapi" and you will reach the signpost of the same name 700 metres further on, just after a path that branches off to the left.
No markings
(4) Leave the track and look for a small path that branches off to the left (due north) behind the sign. It disappears into the vegetation and you will have to bend down at times to move forward through this tunnel of greenery.
Pass a tiny water reservoir and continue. Further up, a cairn marks the start of a path on the left (not shown on the map), but ignore it and continue straight ahead on the same track.
You will come to a first rocky outcrop 5 or 6 metres high, fairly vertical and with medium-sized holds: this will be the most difficult to climb and there is no way to avoid it. Once you have passed this obstacle, continue along the path, passing a large rock shelter and a short scree slope to reach a second tricky passage.
Slightly higher than the first, this ledge will be easier to climb with easier holds. You can see pitons, which prove that this passage must have been equipped at some point. At the top, turn immediately right towards a small platform, as the path is not very visible. Continue climbing and pass a small scree slope, leaving a trail on the left in the scree and heading right to the foot of the cliff.
Blue markings (unofficial)
(5) Continue to the right on the path that runs along the bottom of the cliff, go around it and then start the climb. The markings are sometimes difficult to see and a little faded, so keep your eyes open. When you reach a fork, take the left-hand path (not marked on the map) and you will soon reach another fork.
(6) Continue left and finish the climb to reach the plateau. There is a beautiful view to the left of the rocky ridge of La Roque des Bancs with cedar trees above. Continue on the trail that slopes to the right (northeast), which is sometimes difficult to see in the vegetation, and join a path.
No markings
(7) Turn right onto this path and continue to cistern no. 41, located on the edge of the Route de la Forêt des Cèdres.
Yellow markings + green markings
Continue straight ahead on this tarmac road, passing a path on your left, until you reach the "Le Pré de Roustan" crossroads.
Yellow markings
(8) Turn right onto a path that leads through the cedar trees. After 600 metres, ignore a path on the left (wooden marker) and continue straight ahead on the path marked with a yellow cross. The route is marked with yellow dots. The path leads to a magnificent viewpoint over the Val de Durance.
Continue left, following the yellow dots, and when the trail descends, pick up the yellow markings coming from the left. Continue straight ahead until you reach the "Les Portalas" marker.
(9) Turn left towards the Forêt des Cèdres. The path winds downhill and joins the bottom of the valley.
No markings
(10) Take the path on the right, which is closed by a wooden barrier, cross it and head into the Vallon de Sanguinette. The trail descends, alternating between very wild and dark sections and other more open sections.
Climb down a rocky step of about 3 metres equipped with a rope. Continue downhill until you reach a path.
Red-white + orange markings
(11) Turn right onto the path and follow it for 400 metres until you reach a left-hand bend. Leave the path and take a trail on the right which rejoins the same path 600 metres further on. Follow it to the left and you will come to a crossroads marked with a sign for "Lauris - Vallauris". Turn right and continue climbing until you reach the signpost for "L'Aire des Bosses".
Orange markings
(12) Leave theGR®97trail on your left and continue straight ahead on the path that descends towards Vallon de la Tapi. A little further down, just before a left turn, leave the path that branches off to the left and continue on the same path, which begins a right turn just after. Walk along this path for a good three kilometres before you reach the signpost marked "Vallon de la Tapi".
(4) Continue downhill and head for the house at the "La Tapi" crossroads.
(3) Turn right and follow theGR®97along the same path as on the way there, which will take you back to the car park (S/E).
In the middle of the Arc valley, there is a sign saying "path closed from 1 March to 15 September" to protect large birds of prey (sensitive biological area). So we took a path on the left that climbs eastwards into the woods to reach a small pass. The trail is visible on the OpenCycleMap but not on IGN.
