Description of the walk

Reach La Roche-des-Arnauds via the D994. Park in the car park at the cemetery or town hall.

(S/E) Go up Chemin des Aires, along L'Épervier, negotiate the right-hand bend, then turn left to follow Chemin du Colombier to the bridge.

(1) Take the marked path on the left towards La Tour - Les Baux (left bank of the stream), which leads to the tower. Climb up through the forest to quickly reach the ridge. Make a short detour to the right (there and back) to approach the ruined tower of La Roche-des-Arnauds, where you can enjoy a beautiful view of the village.

(2) Turn back and resume the route by turning right, heading north-east towards Les Baux. Pass under Serre la Gerle and arrive at a fork.

(3) Follow the path opposite, which leads out onto the mountain pasture and joins Serre la Pigne on a rural track.

(4) Continue straight ahead and pass below Lac Peyssier. Continue to a crossroads.

(5) Take the path opposite, heading east (towards Les Baux). When you reach the hamlet, continue along the road to Les Bas Baux.

(6) Take the path on the right at the fountain, below the hamlet, then turn right (south) about 50 metres further on.

(7) Continue straight ahead on a well-marked path towards Petit Buëch until you reach a fork.

(8) Descend on the right towards Petit Buëch. Cross the meadows until you reach the small iron bridge and cross to the left bank.

(9) Turn right at the next junction and return to the riverbank. Follow the riverbank, then cross back to the right bank via a footbridge, heading towards L'Ermitage. Turn immediately left and you will come to a three-way junction.

(10) Take the path opposite, ignoring the access to houses on the right, and join the small road to the Ermitage.

(11) Follow it to the village of La Roches-des-Arnauds, about 1.5 km away.

(12) Once you reach the village, you can return to the starting point via Rue de l'Église or, more directly, via the lower part of the village, going down Rue sous le Barri on the left (marked route). Pass under the town hall and return to the car park (S/E).

Notes

Fountain in La Roche-des-Arnauds (village), above Lake Peyssier (Fontaine Bomboute) and in the hamlet of Les Bas Baux (6).

Panoramic bench at the ruined tower of La Roche-des-Arnauds.

Be careful! The route can become very muddy in places when it has rained in the previous days (paths and fields will then be flooded with water)!

Worth a visit

The ruined tower of La Roche-des-Arnauds (keep).
Built in the 11th century by the lords of Flotte, the simple wooden keep became a solid fortress around the 13th century. As it was the tradition of this lordship to give the first name Arnaud to the eldest son of the family, this fortress on its rocky spur was nicknamed La Roche des Arnauds. The name then spread to the village that developed at its foot.
The panoramic view from this tower overlooking the village is impressive.

Galileo's ball fountain.
Located next to the cemetery car park, this beautiful fountain consists of a marble sphere that rotates on its own axis. Despite its weight, the simple hydraulic mechanism allows even a child to set it in motion!

The first climb is in the shade and quite cool in the morning, but the reward is well worth it with a visit to the archaeological site of La Tour, offering superb views of La Roche.
After the highest point near Lake Peyssier, the views in sunny weather are beautiful (Ceüze, Charance, Crête de la Clape, Rabou Church on its rock, Petit Buech seen from above, etc.).
The return trip down near the stream is pleasant, crossing two bridges, the second of which is "fun" because it moves... and if you want to picnic, there are some nice spots near the stream...
A must-do!

A little-used route (we didn't meet anyone else) with plenty of shade. The description is very clear. A relaxing hike that also allows you to cool off.

An easy and pleasant hike, although some sections are muddy following recent rainfall. Interesting historical description of the tower and the lords who lived in the castle. The two footbridges and the walk along the Petit Burech are pleasant. At the cemetery car park, take a look at the beautiful fountain with a marble sphere that rotates on its own axis.

I recommend it, but not when it has rained heavily beforehand. The trail and fields are flooded...
