Le Pilon du Roi via the four valleys

A very challenging circular route to Pilon du Roi, passing through four magnificent valleys: the Vallon de Mauvelle with its large limestone basins to cross, the Vallon du Pilon du Roi with its strangely shaped rocks that sometimes seem to be watching us, the more accessible Vallon de Fontvielle with its caves and springs, and the Vallon des Escombes, sometimes wild, sometimes calm, with its long tunnel of vegetation at the end of the route. A short stretch of tarmac through La Montade to return to the starting point.

Description of the walk

From Château-Gombert or Plan de Cuques, take the Chemin de la Grave (La Montade district). Park at the end of the road by a gate and a firebreak track where there are numerous parking spaces.

(S/E) Go through the gate and continue along the track until you reach the crossroads with the path leading to Vallon de Mauvelle. After a right-hand bend, take a wide left-hand bend.

(1) In this bend, turn right onto the unmarked path that leads into the valley. Cross a few rocky areas (see practical information section) and you will come to a fork.

(2) Turn left and cross the rock face using the ladder provided. A little further on, pass an old car wreck. Walk past a water retention basin. The path then widens and opens out into a clear area.

(3) Turn right onto the wide path, then take thefirst rocky path that climbs to the right towards the north-east. You will arrive at a hunting reserve (enclosed area), then at the large house of Le Caban. Go around the house on the right.

(4) Behind the house, turn right onto the path that descends under the pine trees. Caution: the descent is steep and slippery.
At the bottom, turn right onto the path, then left to climb north-west towards Vallon du Pilon du Roi. The landscape is magnificent. The last 400 metres are very steep. Stay on the left-hand path to reach the La Limace signpost.

(5) Pass under the Pilon du Roi and turn right towards Col Sainte-Anne, heading east. Stay on the track, pass below the ruins of Notre-Dame du Rot, and reach a crossroads at an elevation of 593 metres.

(6) Turn right towards the south in the direction of a large high-voltage pylon. Pass under this pylon.

(7) Immediately afterwards, turn left, heading east on the narrow path that descends into the heath, passes through a wooded area and arrives between two rock formations, with a view of a cave on the other side of the Vallon de Fontvielle slope.

(8) Turn right at the hairpin bend and descend into the valley. Leave the path that climbs towards the Grotte du Facteur on your right, then pass by a spring with a sign saying "water is rare and precious" (behind it, to the right of the small basin, is the actual spring). Continue downhill through the woods on a pleasant path. Arrive at the bottom of the valley where the path joins a fork.

(9) Go right. Then stay on the left. The path climbs. Shortly after the summit, you will come to a crossroads.

(10) Stay on the path that descends (some patches of tarmac) towards the ruins of Jas de Mimet. Keep to the right as you pass them, then turn left at thefirst intersection. Pass a shed and then some beehives. Join a track and take it to the left. After 200 m, you will come to a right-hand bend.

(11) In the bend, leave the track on the right which leads up a steep slope (at the start) to Puits de Besson, renovated by a hunting association. Pass the well and continue straight on, heading west to the Y-junction.

(12) Turn left, heading south. You will arrive in the Vallon des Escombes. The path is more difficult here, with numerous rocky slabs and potholes filled with water. See the chapter on practical information. The path then becomes flat and pleasant, leading to a grassy, open area where it narrows.

(13) From this point, the trail winds through dense vegetation and bushes. Be careful not to get scratched. Cross a very narrow rocky area and arrive at a long tunnel of vegetation where you will have to bend down to pass through. Arriving at a rock face, the tunnel then becomes inaccessible. Do not attempt to continue.

(14) Turn left onto a barely visible path that winds around the dense vegetation to arrive near a water retention dam. Follow the track that passes to the left of the dam.

(15) When you reach the second dam, descend into the basin. Near the rocks, on the right, there is a passage that allows you to climb above the rocks. Cross the smooth, slippery slabs, taking great care in wet weather. Pick up a path that climbs and passes next to a fire station. Keep left at a crossroads. The path descends towards some houses.

(16) Turn left onto Chemin Bonnabelles, then right onto Rue du Professeur Robert Debré. At the end of this street, continue straight ahead on a small path that passes between houses. Take Boulevard Jean Jaurès then Chemin de la Grave to reach the car park (S/E).

Notes

For information: the author's time was 6 hours 45 minutes (without a lunch break).

Important note:

- The Mauvelle and Escombes valleys are less well known and therefore less frequented. They are not marked on IGN maps as marked trails but as stream beds. You should therefore take precautions if you walk in these valleys. The route suggested here is shown on the IGN satellite map.

- There are many rocks along the route and numerous obstacles that can hinder progress.
- Narrow, overgrown passages (wear long clothing).
- Large, flat limestone slabs that are often wet. Be careful not to slip.
- Large limestone basins that can sometimes be difficult to cross.
- Take care after a storm, as the stream can flow strongly.

Worth a visit

Nearby: The Pilon du Roi lookout, the ruins of Notre Dame du Rot, the Col Sainte-Anne (orientation table and oratory), the Grotte du Facteur, the Baume des Pieds Ferrés, the Tombeau du Roi, springs.

A lovely, varied walk; best to avoid the Crête du Pilon in strong winds like yesterday, but it’s pleasant walking through the valleys.
Thanks for this route

Hello, and apologies in advance for this negative review.

We did not enjoy this hike for several reasons:
- the vegetation is aggressive and luckily we had windbreakers and trousers, otherwise we would have been scratched all over.
- The valleys are steep-sided and the landscape is uninteresting.
- The view from the summit is not particularly attractive (pylons and view of the Meyreuil factory).
- The trails are poorly maintained.
- Hunters were out and about...

Perhaps we have become too demanding from hiking in the Calanques, Sainte-Victoire and Sainte-Baume.

A somewhat long hike. Slightly challenging, but no real difficulties. The view from Pilon du Roi is very beautiful.
Hike completed on 30 November 2025. The arbutus trees were covered with fruit! 😋

An interesting hike due to the variety of the route. The paths are stony, so do not attempt this hike with unsuitable footwear. Some paths could do with some maintenance as there are quite a few brambles and shrubs and sometimes branches blocking the way. Long trousers are recommended to avoid scratches. The climb to the Pilon du Roi is certainly superb but quite steep. If you take certain precautions, this is a hike that I would recommend.

A very beautiful, challenging hike indeed. Suitable for experienced hikers. The climb to Pilon du Roi is very steep. Protect yourself from brambles in the valleys with clothing that covers your arms and legs. The end of the route on tarmac is a relief for your feet and legs.

The route has been cleared, with virtually no brambles, and the tunnel of vegetation has been cut back (at the start of the tunnel, take a small detour to the right and then head back down into the valley), making it easier to pass through.
There are a few large boulders and some jumps that are within reach of experienced hikers.
At the end of the route, at the last dam, take the return path that climbs over the rocks on the right.
Overall, this is a route for regular hikers who enjoy being in touch with nature.
We made a detour to the Col de Ste Anne then rejoined the trail, which made for a total of 19 km with 800 m of elevation gain.

A very beautiful hike that is clearly challenging, the climb to the Pilon du Roi is indeed very steep. The passage through the four valleys is really very pleasant. Long clothing is recommended because of the brambles. At the end of the route, there is a bit of tarmac, but it is good for the legs.

A very beautiful hike with a perfect description. At the end of the route, in the Escombes valley, we missed a small detour, although it was clearly described by Vusky, which would have allowed us to avoid crawling under the brambles and sarsaparilla that have invaded the valley. Look for a tree trunk on the ground on the left and continue slightly to go around it on the right to find the valley a little further on.

Yes, the route is difficult, but by turning off before the end of the last valley, you miss the tunnel of vegetation (site of an American plane crash in 1943).

Very pretty hike, challenging. The last valley after point 13 becomes difficult at the end of the day.
. Between points 12 and 13, you can turn right and return via the valley above Mont Blanc.
