Access: on the D5 road between Le Rove and Ensuès-la-Redonne, park on the left-hand side of the road (take care) in a small designated area (rubbish container) which can accommodate two to three vehicles. This area is located directly opposite a former pizzeria and an upholsterer's workshop.
(S/E) Cross the road carefully and take a wide, stony track that climbs more or less parallel to the road until you reach the Tour d'Ensuès and its picnic area.
(1) Continue straight ahead and, at the first hunting car park, do the same to reach a second car park where you turn right. You will soon come to a crossroads marked by a large rock on the right-hand side and a sign indicating a buried pipeline nearby.
Turn left. A hundred metres further on, don't miss the wide path that branches off to the right and winds its way through low Mediterranean vegetation. Ignore a narrow path on the left that descends very steeply and continue for about fifty metres to reach a fork that does not appear on the IGN map.
(2) Turn left to begin the descent into the Régouvi valley. Join the very steep path you crossed earlier and follow it to the right. At the bottom of the valley, turn left onto a wide track that leads to a crossroads in a pine grove (wire fence and "Réserve de chasse" sign opposite).
Turn right and, at the junction with a track that makes a hairpin bend to the right, continue straight ahead uphill. At the crossroads at the top of the hill (large majestic pine tree), turn left. Ignore a wide path on the right and continue straight ahead to reach a large open space where several tracks intersect.
(3) Climb to the right towards a pretty wood of sparse pine trees. Reach the ridge and continue eastwards, following the power line on your left. When you reach a fork where three tracks lead straight ahead, take the left-hand track and continue climbing. At a large pylon, the view opens up: the Étang de Berre, Mont Ventoux, Sainte-Victoire and Pilon du Roi are easily spotted in the landscape.
(4) As you approach a small valley on the left with a few white rocks, turn left towards another pylon smaller than the previous one (do not hesitate to turn back if you have passed the valley).
(5) This is a tricky junction where I have placed a small cairn. At the foot of the pylon, look slightly to the right for the start of a very overgrown path that is barely visible on the ground. The path curves to the right and descends to the bottom of the valley, where you really have to fight your way through the last five metres.
Turn left onto a much clearer trail, pass a small electrical transformer, then cross a canyon before reaching a wide path where you must turn right. Ignore a trail starting on the left and continue to a hollow in the ground where several paths and tracks converge.
Turn left onto a wide path that curves sharply to the right before reaching a flat area. At the second grassy section, turn right at a 90° angle and continue for about 50 metres.
(6) This is a tricky junction where I have placed a small cairn. Bear left and look for a very faint trail on the embankment, which is particularly difficult to follow in the short vegetation but becomes clearer about 50 metres further on. At the next fork, take the narrow path on the right, which descends steeply and then levels out, curving to the right towards a small gorge that marks the beginning of the Juan valley.
(7) At the junction with a stony track, turn right and then right again at the next intersection to quickly reach a beautiful grassy, shaded area, ideal for a break, provided you stay away from the beehives attached to the rock face. Then climb up the wild Juan valley, which is very steep but widens out at a small pine plantation where a track joins from the left.
(8) Turn right and follow this track up to the first hairpin bend (elevation 158), where you should leave it and take a wide, partially grassy path on the left. Continue for about 400 metres until you reach a fork marked by two yellow painted markers (underground gas pipe) and a sign indicating a nearby pipeline.
(9) Start climbing the very steep slope on the right, which leads to a flat area where you will join a stony track. Follow this track to the left until you reach a metal barrier (information sign about the Conservatoire du Littoral).
Go around it and immediately turn right, walking alongside a few boulders arranged in a line. Follow a wide double track path overgrown with short grass. At the first fork, turn right, then at a solitary pine tree (be careful not to miss this intersection), turn left onto a narrower path that makes a wide circular loop to the left before joining a track at a concrete telephone pole.
(10) Turn right and continue along the power line. Begin a short descent (beautiful view of Ensuès-la-Redonne), pass a first path on the left, then take the next one, also on the left, to quickly reach a crossroads (small solitary pine tree).
Do not continue straight ahead but turn right to avoid hitting a large area enclosed by concrete walls that can be seen below. Ignore a path on the left.
(11) At the next junction (small cairn), turn left, go down the slope and then climb up opposite to reach the Tour d'Ensuès.
(1) Turn left to return to the starting point (S/E).
