Departure from the car park located at Impasse de Manon des Sources.
(S/E) With your back to the car park, turn right and then take Avenue du Pont on the left, where you will have a nice view of the castle ruins. Walk towards the roundabout and then towards the D46a (Route du Régage).
(1) About ten metres after the roundabout, leave the tarmac road. A small path climbs steeply up to the left towards the woods. It is marked in yellow. Follow these markings at first.
(2) Nice view, continue along the path.
(3) Immediately turn left onto the small path that descends just after the hunter's cabin, still following the yellow markings. You will descend into the valley. At the bottom of the valley, you will come to a small stream. In wet weather, a trickle of water flows in places. In the middle of summer, it is completely dry. However, after heavy rain, you can see a beautiful waterfall and several pools filled with water (see photos).
The yellow trail crosses the stream bed several times. It seems to disappear at one point among the rocks, but you can find it again without too much difficulty.
(4) The path then leads to a forest firebreak track at a barrier. Take the path uphill to the left. A little further on, it is concreted for about 100 metres.
(5) At the top, at a new gate, leave the yellow trail and the DFCI track and continue climbing to the right towards a hunting cabin, which you will pass.
The path continues to climb and then descends. You will then return to the DFCI track. Turn right at this intersection. The DFCI track descends to a small house.
(6) You are now at Font de Mule. About 500 m further on, there is a spring that flows all year round, but you will not pass it (see below for points of interest near the hike). Turn left at point 6 towards the small house, go through the gate and follow the path. The path runs alongside a small field and then plunges into Mau Vallon (meaning "bad valley").
This takes you down into the old bed of a stream. The valley is shaded and quite narrow in places. This path leads to the Chemin des Mules.
(7) Turn left and walk up this concrete path for about 50 metres.
When you reach the last house at the top of the path, a trail branches off to the left. This will take you up another valley.
(8) Turn right towards a ruined sheepfold 300 metres further on. Turn right at the sheepfold. The path passes behind the sheepfold. You will then come to a fork; take the left-hand path. Further on, a small path descends to the right towards a tarmac road: the "Montée de La Bergerie".
Cross the D7 and take Rue de La Source, then Avenue des Pegoulières. Follow this road to the end towards the village.
At the end of this avenue, turn right onto Avenue des Bellonnets, then Rue de l'Abbé Émile Vallier. Climb up towards the castle ruins, passing behind the church.
Then head back down Rue de l'Église to Place Louis Julien.
Further on, turn right onto the D46a and after a few dozen metres you will reach the car park where you started (S/E).
