(S/E) Park in the car park in front of the abbey. Head east and take the path that runs alongside the D561a. Cross the D23 with caution and continue along the D561a for about 40 metres.
(1) Cross this road with extreme caution as there is no pedestrian crossing. Take the forest track (DFCI 221) on the right, which crosses the Marseille canal further on and climbs gently towards the ridges. The noise of traffic in the valley gradually fades away.
(2) Pass cistern 322 and reach the junction with cistern 186 just after leaving a track on the left.
(3) Ignore the Vallon des Pierres Rouges path on the right and continue straight on to cistern 162.
(4) Take the path furthest to the right, which descends gently into the forest until it crosses the Vallon de la Baume path.
(5) Turn completely left and continue along the hillside until you reach the EDF THT pylon located about a hundred metres before another cistern.
(6) Take the small path on the right that passes under the pylon and descends into the valley. The path quickly follows the course of a (dry) stream at the bottom of the valley. Be careful, as the stones can be slippery. A small 5-metre-high stone waterfall requires particular attention but is easily passable using the few roughly hewn steps. You will then reach a pleasant path through pine, boxwood and oak trees.
(7) At the end of the valley, after passing a wide path on your right that leads back into the mountains, walk along the sports fields and then cross the Marseille canal
(8) After the canal, immediately turn left onto Rue du Castellas, cross Boulevard de la Paix, keeping to the left to use the pedestrian crossing. Continue for about 20 metres, then turn left onto Rue Albert Camus. Walk past the old town hall, then continue straight on Rue Georges Clémenceau.
(9) Turn right onto the small Rue de Vaudois, which ends in an alleyway. Turn left onto Rue du Temple, take a look at the Protestant temple and the information panel on the history of the Waldensians in the valley. Continue along this street, then turn left onto Rue de la Calade, which will take you to the castle
(10) Follow Avenue de Silvacane to the right. This is the least pleasant part of the route, with poorly maintained verges.
(11) Keep to the right at the three-way junction and continue straight ahead.
(12) Just before the T-junction, at the pedestrian crossing, turn left onto the path that runs alongside the road to reach the car park (S/E).
