Take the D5 at Ensuès-La-Redonne and head towards Port du Rouet via Avenue du Vallon de l’Aigle. Park in the Rouet Plage car park (chargeable during the summer season).
(S/E) Head east (with the beach on your right) and walk for about 450 m along Avenue Blanche Calvet, then along Chemin des Eaux Salées. You’ll come to some steps on the right.
(1) Climb the steps to reach the esplanade of the Notre-Dame du Rouet Chapel. Explore the area, then retrace your steps.
(1) Turn right, then immediately left towards the DFCI CB111 track. Do not go onto the track but pass to the right of the fence and follow the light blue-marked path which descends to the right towards the east, runs alongside the railway line and leads to the Calanque des Eaux Salées beneath the magnificent viaduct. Note the seawater springs emerging from the pebbles. Admire the scenery. Pass under the viaduct and climb the numerous stone steps.
(2) Turn left onto the light blue-marked path. Further on, turn left at a light blue-marked Y-junction. Keep to the left and you’ll reach a junction with a track and a signpost.
(3) Continue straight ahead towards the Plaine du Bon Jean. After a sharp bend to the right, you’ll reach another signpost.
(4) Turn left onto the narrow path towards Le Bon Jean. After a stony descent, you’ll reach the vicinity of the D5 road. Walk alongside it on the left for about 150 m, heading towards La Plaine du Bon Jean, as indicated on a sign.
(5) Cross the road carefully and follow the unmarked but clearly visible path. This path winds its way northwards for some time through the Vallon du Bon Jean. Pass through a tunnel under the D9 dual carriageway at elevation 107. On the other side, the path heads off to the left through vegetation that has been spared by the fires. You’ll reach a Y-junction at elevation 106.
(6) Turn left and continue westwards. You’ll reach the foot of a high-voltage pylon and a junction of tracks.
(7) Turn left, then continue straight on southwards towards an underground cistern no. 341 at elevation 165. Rejoin the track further down and arrive at a Y-junction at elevation 132.
(8) Turn left towards Bon Jean, then further on, keep left, continuing in the same direction. You’ll catch a glimpse of the coastline. You’ll reach a Y-junction.
(9) Turn left towards the Vallon de Jaume, following the yellow and blue markings. Pass by the valley’s AOC olive grove, then reach the tunnel under the D9 at elevation 80. Go through the barrier.
(10) Turn left and continue the descent into the Vallon de Jaume. The path is narrow but easy to follow. After about 650 m, look out for a cavity carved into the rock on the left, containing old concrete structures.
(11) Turn left onto the path that runs past the cavity and walk for about 150 m. You’ll come to a Y-junction.
(12) Turn right onto an unmarked and barely visible path, heading south then south-west (GPS recommended). Ignore the paths to the left and right and stay on course. You’ll reach the top of a rock face.
(13) Carefully climb down a few rocks, using your hands for support, and you’ll come across the Grotte du Rouet on your left. Explore the area and then head back the way you came.
(13) Keep to the left, follow the ridge and you’ll soon reach a roundabout and some houses. Walk down the steep tarmac road known as the Montée de la Grotte to return to the starting point of the walk (S/E).
