Park in the car park of the Pavillon de Chasse du Roi René, located on the right on the D7 connecting Luynes to Gardanne.
(S/E) From the car park, enter the landscaped park and walk to the banks of the Luynes river, then turn right onto the path that runs alongside the river (not shown on the IGN map). Leave the hunting lodge on your right. Walk to the wooden and cable footbridge and cross the river.
(1) After following the river, the path veers to the left (do not take the path on the right). Pass under the SNCF bridge and you will reach a vineyard. Take the path on the right and continue until you reach a small bridge, then take the path on the left which climbs steeply. You will then reach a small wooded valley. Climb straight up the rocks and rejoin the path above the rocky outcrop. Turn left and climb. You will soon see the chimneys of Gardanne.
At the fork, turn left (do not go up to the right). The path then runs along the left side of the factory road. The path approaches the factory buildings; continue along the main road via the path below.
(2) When you reach a path under a power line, turn left and continue straight ahead until you reach the road. Immediately take the path on the left that climbs to point 305. Continue downhill, following the power line. Pass a first crossroads with four paths and continue for a few metres to reach a second crossroads.
(3) At this four-way junction, turn left and you will come to a barrier marked MT202. Go through it and take the path that goes straight ahead (do not turn right or left). Continue straight ahead.
(4) Enjoy the view on your right: Sainte-Victoire Mountain, the slopes of the Valabre hills and the Gardanne power station. Continue straight ahead on the path, ignoring the path that descends to the left.
(5) Pass under the SNCF bridge and join the road. Turn left, pass the "Lycée Valabre" bus stop, then before the bridge over the river, take the path to the left of the road.
(6) Cross the wooden footbridge over the Luynes, then turn left onto the path that runs alongside the river.
Stay on this path until you reach the Pavillon de Chasse du Roi René and return to the car park (S/E).
