Park in the car park on the right on the road to the Ecomuseum, which you take on the left from the D7. The car park is 200m after the crossroads.
(S/E) Leave the car park via the road on the right that goes uphill. Continue for 300 metres and take the first road on the left, still uphill. The road then becomes a track.
(1) When you reach the hunters' car park, go through the gate on the left opposite. From this point, the hike follows the yellowPR® markings. After a short climb, take a small path on the left.
Very soon, you will see a viewpoint over Gardanne and the Étoile massif with the Pilon du Roi. Be careful, as the path runs along cliffs. The small path rejoins the main path. Take it on the left and continue straight ahead, leaving a path on your right.
(2) Don't miss the path that branches off to the left and is marked in yellow. On the left, you will see the cliffs. Follow the ruined wall. At the corner of the wall, at the sign saying "dangerous area - risk of collapse", keep to the path that crosses the wall through a passageway and follow the yellow markings. After a steep climb, the view opens up onto the Milles area: continue straight ahead, do not take the path on the right that leads to the antenna and you will come to a wide path.
(3) Cross the path (there is a wooden sign saying "Attention, passage de véhicule" [Caution, vehicle crossing]), the trail continues opposite, uphill, and then joins the path you crossed earlier. Continue along the path that descends to the right and join the leisure park, which you follow on the right.
(4) Join the D7 road and follow it to the SNCF bridge, then turn right and follow the railway line. Keep right on the marked path and cross a first path.
(5) Take the path on the right that goes uphill. At the top, go past the corner of the ruined wall and turn right to reach a gate.
(6) Keep left, do not go through the gate. The path is paved for a few metres as it passes the buried cistern. After a descent, you will come to another gate a few metres before a crossroads. Take the right-hand path which descends and joins the hunters' car park.
(1) Continue straight ahead and retrace your steps until you reach the Ecomuseum car park (S/E).
