Go to La Penne-sur-Huveaune via Boulevard Voltaire. At La Penelle, turn right onto Boulevard Jean-Jacques Rousseau. On this road, take the second street on the right, then Chemin Raymond Retor, towards "Aqueduc/Forêt Penne-sur-Huveaune". Park after the aqueduct, where there is easy, shaded parking.
(S/E) Pass under the aqueduct and walk along the north side of the structure. At the fork at the edge of the woods, turn left and stay in the woods. Follow the wide dirt track to the cemetery wall.
(1) At the crossroads, take a small path opposite, which becomes more enclosed and shady. At the next fork, turn left and head south-east. The path then leaves the forest and reaches an open area, which is the highest point of the hike.
(2) Take a forest path to the right and then turn left with it. At the next junction, continue straight ahead (east then south-east). Stay on the main path and pass under a power line. You will arrive at a flat, wooded area.
(3) Then turn left. Walk north-west and ignore the paths branching off to the sides. Follow the forest track to the aqueduct and then the car park (S/E).
