Description of the walk

Access: Reach the car park via the D80. Cross the village of Nans-les-Pins and, when you reach the centre, do not turn left towards Sainte-Baume, but continue straight ahead on Boulevard de la Mecque until you reach the Chapelle des Pénitents Blancs. Then turn left onto Chemin de l'Orge and park in the small car park on the right, close to the chapel. If there are no spaces, continue along Chemin de l'Orge to park further away at the side of the road.

(S/E) Walk back towards the Chapelle des Pénitents Blancs, go around it on the right and start this hike by following the yellow markings on the concrete path heading south-west.

(1) At the first fork, continue straight ahead towards the Huveaune (yellow markings). Continue west-southwest. At a fork (altitude 510), follow the left path and continue along the hillside until you reach a cistern.

(2) At the crossroads, continue straight ahead (yellow markings) and descend to the intersection with a path on the left.

(3) Follow this path marked with a yellow cross, which will take you to the right bank of the Huveaune and the "Chemin des Aumèdes" track. At this point, turn right and cross the wooden bridge over the Huveaune.

(4) Turn left to follow the Huveaune river along its left bank. At the first bend to the right, turn left and head back down towards the river. Follow the path that runs alongside the river, heading south-east then south. Further on, admire the magnificent natural rock pools.

(5) At the two wooden bridges on the left, cross and follow the path to the south (green markings) which climbs towards the Grotte de Castelette.

(6) At the first crossroads, there are no signs, but turn right (west) to reach the entrance to the Castelette Cave (green markings).

(7) Retrace your steps.

(6) Back at the crossroads, turn right towards the south (green markings) to reach the Plan d'Aups plateau. Magnificent view of the north face of Sainte Baume and the southern slope of Sainte-Victoire mountain. Continue following the green markings.

(8) There is a shorter alternative route at this point. See practical information.
Otherwise, continue slightly uphill towards the south until you reach a junction with a track, following the green markings.

(9) Follow the track to the left (east) until you reach the junction with theGR®9, marked by a sign on a tree on the right.

(10) Follow theGR®9to the left (north-east, red and white markings). Cross the D80 and continue along the Sentier des Roys (north-east) on theGR®9. Leave the road, walk for about 550 metres and, at a fork, turn left (GR®9) towards the Oratoire de Miette, which you will reach 300 metres further on.

(11) Begin the descent towards Nans-les-Pins. Walk 700 metres and cross the Nans-les-Pins road (D80) again. Continue down the windingGR®9until you reach the junction with theGR®9A.

(12) At this point, leave theGR®9and continue right (north) on theGR®9A(red and white markings). Follow the road for 300 metres and cross the road on the left. Walk alongside the buildings of a horse farm.

(13) Leave the discovery trail on your left and continue straight ahead. Pass through the hamlet of La Jolie and follow Chemin de l'Orge north to the chapel car park (S/E).

Notes

This hike requires good walking shoes and plenty of water.

(8) Turn left and take a very pleasant path that runs under a small rocky outcrop at the edge of the plateau and joins the D 80, which you cross to reach the Chemin des Roys.

Worth a visit

1) Origin of the pools. Explanation found on the internet:

Near its source, the water of the Huveaune is turquoise in colour and magnificent basins have formed. This colour is thought to be due to the presence of bacteria. These bacteria have accelerated the chemical reaction and layers of limestone have been deposited on the branches and leaves that have fallen into the stream, forming "petrified" basins.

2) Chemin des Roys: a path that was used by many kings of France, popes and pilgrims travelling from Saint-Maximin to the Grotte de Marie-Magdeleine. This cave is located in the Sainte-Baume cliff above the hostelry. There are also oratories along this route. These allowed pilgrims climbing the holy mountain to pray and meditate, but also to stop and rest.

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

A lovely walk. We set off early in the morning to make the most of the springs and pools. Because after 11.00 am, it was absolutely heaving.
As for the route, it was relatively easy up to the pools and the cave. The return via the green route was trickier just after the cave as it was barely visible, or rather, not very visible.
It’s very important to have a fully charged phone and perhaps a spare battery to follow the route on Viso Rando.
Apart from that minor hiccup, it’s perfect.

The walk is particularly interesting, but the problem is finding a parking space in NANS LES PINS at the start, especially on Sunday 19 April!
The route was very busy, and the village of Nans is absolutely lovely!

A fairly long hike, covering 16km and 983m of elevation gain in just under 6 hours, chosen because of the strong Mistral wind up in the hills. The approach walk was a bit long, but good for warming up before tackling the Humeveau and its pools. It felt as busy as usual; groups of pensioners were doing the route in reverse that day, on a weekday. At the weekend, it must be a real struggle.
The pools are lovely with their little waterfalls. Great for photos. The cave above is quite off the beaten track and not much to write home about. The view over the Plan d’Aups is magnificent, with the path winding through the open trees. The descent is a bit long with quite a few stones. All in all, a good hike with some interesting sights, but a bit long. Also worth seeing are all the wayside shrines...

A very beautiful hike, done in the rain with the Huveaune river so high that it was impossible to ford. The Castelette cave is not to be missed. Magnificent arrival on the plateau at the foot of Sainte-Baume.

A very interesting hike with a variety of landscapes, particularly along the Huveaune and its magnificent pools, but the description is rather confusing and lacks detail (the yellow cross markings are confusing as they normally have a completely different meaning), and following the GR9 at the D80 is unpredictable. A GPS is very useful.

A very beautiful route, which we did in winter. The springs were flowing, except for the highest one. At this time of year, the valley floor is very cool. We ended with a short detour to Nans le Vieux. Not to be missed!

The ideal hike takes place 3 to 4 days after rainfall, and in spring this is when the colours of the water in the pools, ranging from green to blue, are at their most magnificent!

A very beautiful hike in superb winter weather. Beautiful view of Sainte Baume and Sainte Victoire.
In the distance, the snow-capped peaks of Chiran and Moure de Chanier (Verdon). The Castelette cave, with its large chamber, ends in a siphon. Climb back up to the cave at point 772 via a steep path. Beautiful view from the summit, with a magnificent sunset.

We completed the route with a visit to the old village of Nans. Access from point 13 in the description requires a bit of navigation. Otherwise, there is a good path a little further to the left that leads to the entrance of the marked area. It's an interesting opportunity.

A very beautiful hike through varied landscapes. There was no water in the pools at this time of year, but we will do the hike again in spring! You absolutely must visit the cave, which is magnificent (bring a headlamp if possible). There is a nice little platform for picnics (beautiful view) 200 metres from the cave, taking the path that goes uphill. After going to the cave and back, the climb out of the valley is quite steep but in good condition (didn't see any green markings, so thanks to Visorando for the trail!). The return trip is quite long (you may want to use the alternative route at point 8 to shorten it a bit) but not difficult.

A beautiful hike, but best done when the spring is flowing.
The climb up to the plateau is quite degraded by recent rains.
The descent via the Chemin des Roys is similarly dangerous for ankles.
Significant erosion and no recent maintenance.
Best left for spring when there is water.

A good level of walking on varied and very pleasant trails, mostly in the shade, so I recommend this hike in hot weather

It's always a pleasure to hike in the Massif de la Sainte Baume and admire the sources of the Huveaune. Especially after a very rainy winter. Admittedly, the climb from the sources to the plateau is always a challenge, but we love to suffer at times like these.

The hike is signposted from the start in Nans, from the small car park near the chapel. Very pretty and can be adapted to suit different lengths. Best avoided at weekends.
