Circular above the Plan du Castellet

A very easy walk that will allow you to see some fossils, surrounded by vineyards and olive trees, with beautiful views of the hilltop villages of Le Castellet and La Cadière d'Azur. Between 1824 and 1949, a lignite mine (a type of coal between peat and hard coal) was operated at the Fontanieu site; a few very discreet remains of this operation can still be seen here and there. Those interested in geology will enjoy "reading" this landscape.

Description of the walk

If you are coming from Bandol, take the D559b road that follows the motorway. Just after passing under the motorway, turn left into the tunnel that goes back under the motorway (towards Domaines Bunan) and park in the car park on the left at the tunnel exit, opposite the recycling bins.

(S/E) Take the small road that climbs north-west towards the Bunan estate, along the small Vallat de Fontanieu stream. You will soon come to a crossroads with a footpath.

(1) On the left, in the middle of the vegetation, is a clay quarry that was once accessible via the path that starts at the edge of the vineyards. This site, which contains a large number of fossils, is currently inaccessible as it is private property.
Continue along the road. Further up on the right, you will see large buildings that are former miners' dwellings, converted into a rural lodge.

(2) In the bend above, you can climb up to the left along the Vallat de Fontanieu to search the rocky embankment on the left.

(3) Return to the road and continue to the left.

(2) A little further up, take the road on the left at the Chemin de Fontanieu Bis sign. You will climb up to a pretty cirque-shaped site with terraced vineyards and olive groves. You will reach a crossroads in the embankment in front of you.

(4) Take the road on the left, and after about 600 metres, crossing the Vallat de Fontanieu valley, you will find the Fontaine de Fontanieu fountain below the road.

(5) We retrace our steps to the previous crossroads.

(4) Continue straight ahead until you reach the Bunan road.

(6) Turn left onto this road, heading towards the Bunan estate, whose château you will reach after 500 metres.

(7) In front of the château, you can enjoy a break in a pretty little park laid out for visitors.
Continue along the road, passing a wall above which you can see a huge barrel. At this point, the road ends and continues along a rocky path marked GR®. After crossing a wooded area, you come to an open space with a clear view of the Pibarnon estate and its château.

(8) Retrace your steps and take the path that descends to the left towards the north and passes through vineyards. Soon, this path descends steeply in the form of a sunken lane in a very clayey area. Be careful, this section is almost impassable when it has just rained and requires the use of a pair of walking sticks.
After this perilous descent, you come out into a very open area of vineyards, with a magnificent view of both the hilltop village of Le Castellet and La Cadière d'Azur. Further down, you pass the pretty hamlet of Le Moutin on your right (but there's no reason not to stop off there) and continue downhill towards Fontaine Saint-Jean.

(9) Continue up to the right along the Chemin de Saint-Jean until you reach the crossroads, where you turn right onto the Chemin de l'Argile, which first crosses the Vallat de Saint-Jean before climbing back up towards Bunan.
You will arrive at the entrance to the Gros Noré estate.

(10) Continue south along Chemin de l'Argile, remembering to turn around from time to time to admire the view of La Cadière, Le Castellet and Le Beausset. Head towards Domaines Bunan and join Chemin de Fontanieu.

(6) Continue south. After a crossroads where you pass the Le Soleil de Fontanieu guesthouse on your left, continue down this road until you reach the crossroads you passed on the way there.

(2) Retrace your steps until you reach the car park where you started (S/E).

Notes

Water points at the Fontanieu Fountain and the Saint-Jean Fountain, which always have water and are very cool in summer.
The entire route can be completed with light walking shoes or even trainers, except for the very clayey section after (8), where good shoes and a pair of walking sticks are necessary in case of wet ground after a period of rain.

Worth a visit

(S/E) Shortly after setting off, about twenty metres further on, you can see stepped basins in the stream bed, reminiscent of the well-known Huveaune springs, but on a smaller scale. These formations were created in exactly the same way, by the precipitation of dissolved limestone under the effect of bacteria, forming a vacuolar rock known as travertine. A block of this rock can be seen in the embankment on the left: you can clearly see the voids corresponding to the plants around which the calcium carbonate has been deposited.

(1) The old clay pit: sediments rich in clay were once mined here, containing large quantities of fossils, mainly bivalve molluscs, including numerous oysters, and gastropods (notably turritella). These fossils are easily visible and can be collected from the blocks that have fallen from the quarry face, but the site is no longer accessible. We should just note its existence, which is undoubtedly the origin of the name "Chemin de l'Argile" (Clay Path), one of the roads in this area.

(3) Rocky scree on the right bank of the stream, traces of rudists can be seen. These are fossil shells shaped like ice cream cones, from an organism that lived in a reef environment and dates back around 80 million years.

(4) Here we can see rocks with a very distinctive, vacuolar appearance, known as cargneules. They were formed by the dissolution of limestone by high-temperature, high-pressure water circulation during major tectonic events (faults, folds). It should be noted that it was in this region that geologist Marcel Bertrand discovered the presence of thrust sheets (Beausset anomaly) around 1890.

(5) Fontaine de Fontanieux: this fountain is fairly well preserved and consists of three basins, two of which were used as wash houses and one as a drinking trough for horses.

Between (6) and (7), if you look closely at the embankment on the left, you will see that the earth is unusually black: this is because it contains large quantities of lignite fragments from the former mine.

Between (7) and (8) On the other side, in the field behind the hedge, you can see that the soil is very rich in lignite. Further on, at elevation 220, the road overlooks the hamlet of La Charbonnière, a name that leaves no doubt as to the former activity of the area.

(8) On the right, in the embankment, you can see layers of limestone and marl rich in fossils of lamellibranchs and gastropods, as well as layers of gypsum.

(9) The Saint-Jean Fountain dates from the 16th century and is fed by water from the Défends hill via a Roman aqueduct. You can walk down to the fountain to admire its architecture.

(9) From the Saint-Jean Fountain, the more adventurous can extend their walk by climbing up to the village of La Cadière, which is well worth a thorough visit.

(10) Domaine Gros Noré: here you can see an old masonry well topped by a beautiful specimen of a hundred-year-old olive tree. Another ancient well, overgrown with very old ivy bearing a large quantity of fruit, is located 50 metres away on the road leading up to Le Moutin.

Between (6) and (2) A little further down on the right, you can see the rocky embankment, where there are a large number of rudists, which are unusual in that they are upside down: the upper part is facing downwards (and the tip, which is their base, is facing upwards), which means that the geological formation that contains them has been inverted.

I completely agree with you @JL56: spring or autumn (or even winter) are the best seasons for this hike (as for most hikes in the Var). As far as I'm concerned, anything but summer!
Also, yes, this walk includes a lot of road sections. But you can see that very clearly on the map!
And for this tour, it's difficult to do otherwise.

A lovely little hike offering beautiful views and winding through the Bandol vineyards between La Cadière d'Azur and Le Castelet.
One downside is that there are many small tarmac roads, especially at the end, which can be a little tricky to manage with a group of around twenty walkers given the traffic... What's more, it's hot in June and the tarmac doesn't help... It's better to go in May.

@Bernard MARCELLIN, you surprise me: I do this walk very regularly, and I have never been bothered by traffic on the road sections of the route. At most, you might encounter a vehicle from time to time, but in that case, it's no problem to pull over to the side of the road. If I am to believe the other previous reviews, no one has complained about the traffic. But perhaps you had a bad day.
That said, in this part of the Var, it is very difficult to find routes that are completely free of road sections, but outside the summer season and away from the main roads, the traffic is rarely a problem.

@Phil83, here's a testimonial that makes us happy: what could be better than spreading joy?
That's the goal of all of us who contribute to Visorando: after discovering many hikes that have brought me happiness thanks to this great site, what could be more natural than to share my own hikes with others through this same site? Visorando should be declared a public utility.

A lovely, varied walk: small roads, paths, trails, pine forests, vineyards, olive groves, several wine estates (Pibarnon, Bunan, Gros Nore), beautiful views of the villages of Le Castellet and La Cadière, and a few sea views. In short, pure bliss.

We took previous comments into account, but work on the vineyards has changed the route and it is now difficult to find your way around. The Bunan park is undergoing work, as is the area much further on, beyond the forest; that is the most complicated part. Beautiful views.

nice hike, but be careful not to follow point 1 because access to the quarry crosses private property and
we were forced to turn back after talking to the owner!
The rest of the route is pleasant, but you need a GPS, otherwise it's a pain to find the right path through the vineyards to reach the long descent to La Cadière.

First ride of 2022 to get back into shape.
Very good, the conditions were exceptional.
Lunch break around 8 o'clock, facing the sea and Pibarnon Castle.
No difficulty
We did not take the first detours (1 & 3) following the advice of previous hikers.

A lovely walk with magnificent views, but the two small extensions from the starting point are either difficult to find or lead to a sort of rubbish tip...what a shame!

Hello,
the route for this hike is no longer signposted, with no painted markings. Much of the path is paved.

We couldn't find the quarry. We went round in circles. After a long circular route, we ended up back on the main road, back at the car park. The locals don't know where it is.
We finally followed the GR trail towards the Dunan estate and then towards La Cadière. We'll do that next time. We covered 13 km.
Thank you
