Park next to the town hall, Place de l'Église.
(S/E) Take the road opposite the church (PR®48well signposted all the way up), at the Treilles crossroads, take the path on the right and continue along the trail to cross the stream. After the fence, turn left, then take the road on the left that climbs towards the cliffs. Reach the hamlet of Mouilleron.
(1) Continue along the path that passes above the farm building, climbing in numerous bends through meadows and woods. After a ruin, turn right. The path climbs westwards through a remarkable beech forest. At the exit of the woods, pass in front of a stone house (superb) and come out onto the road.
(2) Turn right and continue to the Ouvrières crossroads, then climb the road on the left. At the second bend, take the path on the right into the woods. At the edge of the woods, follow the edge of the meadow (fence). Climb up the valley on the hillside and cross the marl. You will come out onto a carriageway.
(3) Turn left for a few metres, then right, and climb the slope under the pine trees (very steep).
At the Tournelle crossroads, continue straight ahead. The path climbs up a hillock and then zigzags.
At the edge of the woods, climb the scree of large stones at the foot of the Tournelle, then climb the rock chimney (the passage is equipped with metal handles but there are not enough of them, so be very careful not to slip!)
Caution here: At the top of the chimney, it is possible to climb to the summit of La Tournelle, but it is not very safe.
Once at the top of the chimney, climb up to the right onto the grass!
(4) Follow the path and walk along the ridges (not very well marked but follow it roughly) until you reach the first summit, then continue to Serre Gros (still steep) where you will encounter horses on the plateau!
(5) The path descends towards the south-east along the ridge, plunges into a beech forest, goes around a hillock and descends straight down to the Pertuis pass.
(6) Turn left and descend the slope through the undergrowth (very tall beech trees), a dark wood but with a soft carpet of leaves.
Descend to the junction with the Bisquerle trail. Continue to follow the red and yellow markings of the Tour du Pays de Die to the village. Cross the village and turn left at the bridge to return to the car park (S/E), but not before visiting the village.
