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).
