The Grospierres ridges from Le Rouret

Following good paths through holm oak trees, this hike will take you to the ridges of the Grospierres hills with beautiful views, sometimes towards the Basse Ardèche on the south side, sometimes towards the mountains on the north side. On the way back, you can see the Notre-Dame des Songes chapel, the abandoned village of Chastelas and the Font Vive resurgence with its green water.

Description of the walk

(S/E) From the car park, take the road eastwards and after 200 metres, turn right onto the road that goes around the riding centre buildings and runs alongside the car park. Continue along the path that extends this road until you reach the entrance to the hamlet of Le Rouret.

(1) Turn left onto a path heading south.

(2) Just after a concrete crossing over the stream, turn right. Continue to the hamlet of Les Laurents Hauts. Turn left onto the paved road, which continues as a dirt road. At the first intersection, leave the main road on your right.

(3) After a short climb, at a three-way junction, take the right-hand path. Continue until you reach a wide path on the left. Continue straight ahead, ignoring the paths on the right and left, until you reach the D202.

(4) Cross the road and take the path furthest to the right, which runs almost horizontally. A small, inconspicuous wooden sign indicates the direction of the Fontamille spring. Leave a path on your left, then another on your right, and continue to this spring (spelled Fontameille on the IGN map) and then to the ridge.

(5) Turn left and follow the path on the ridge, marked in white and yellow, until you reach the D202 at the Col de la Serre.

(6) Take the road on the right, descend to the first bend and turn onto a path on the left. This continues along the mountainside at roughly a horizontal angle. Leave a path climbing up from Bessas on your right.

(7) Leave a path climbing up to the summit of Puy Lacher on your left and turn right to descend towards the Col de Trépaloup. Continue straight ahead towards the Col de la Cize.
A little further on, still following the white and yellow markings, leave the main path and take a trail on the right. Continue along the ridge towards Serre de Colombou.

(8) At the hiking sign, leave the path to Bessas on your right and continue towards Col de la Cize.
At the next sign (be careful, it is difficult to see in the vegetation), leave the Col de la Cize and take the path on the left that climbs towards the ridge in the direction of Notre-Dame des Songes.
On the descent after the ridge, be careful of slippery rocks in wet weather in the first section. Continue following the white and yellow markings.

(9) At a four-way intersection, continue straight ahead and follow the red and white markings forthe GR®4.
Pass by the Notre-Dame des Songes chapel. After the chapel, ignore the first path on the left.

(10) Immediately after, leave theGR®4and take a wider path on the left. About 50m after, take a path on the right that leads to the ruined village of Chastelas.

(11) Take a path on the right, cross a grassy area and piles of stones - probably the remains of the castle - to reach the rock at the end of the promontory, where you will have a beautiful view of the valley.
Retrace your steps to the last crossroads.

(11) Turn right onto the path that descends and continue through the ruins along the narrow streets and steps to the bottom of the village, where you will rejoin theGR®4trail.

(12) At the Font Vive hiking signpost, turn left towards Résurgence. Walk along the bottom of the village on the west side and take a path on the right that descends towards the Font Vive spring.

(13) After the spring, the path that runs along the stream on the right bank is now blocked. Retrace your steps to the bottom of the village of Chastelas.

(12) At the hiking signpost, rejoin theGR®4and keep left at the fork with a cross. At the next fork, note the large cross on your right and continue between the buildings until you reach a track that runs along the valley. Follow it to the right and continue to the end of a paved road.

(14) Turn left, cross a car park below and continue along a path that crosses the stream. Continue to follow theGR®4markings.
At the top of a climb, leave theGR®4, which turns right, and continue straight ahead.

(15) At the next junction, leave the white-and-yellow marked path on your right and continue along a stony track that climbs into a pine forest.
Join the road that turns left towards the equestrian centre and the car park (S/E).

Notes

To reach the starting point: coming from the north on the D111, pass the junction leading to Grospierres and, on the straight road, turn left towards the village of Le Rouret. Turn right then left, following the signs for Pierre et Vacances.
When you reach the village, pass the equestrian centre on your left and a private car park on your right. A visitor car park is available on the left just after this.

Much of the route follows thePR® Blanc-Jaune signposts.

Alternative route: Between points (6) and (7), you can also go via the summit of Puy Lacher; the view is even more beautiful but the descent over the rocks is quite difficult.

(13) At the Font Vive resurgence, the path that continues down the valley is closed, so you must turn back. This site is located in a Sensitive Natural Area. Swimming, littering, camping and lighting fires are strictly prohibited. This resurgence is located on private land, and access is tolerated by the owners, who are entitled to prohibit access if abuse is observed.

Worth a visit

The village of Chastelas was dominated by a medieval castle built on a rocky promontory. It was gradually abandoned during the last century. Completely uninhabited since 1930, it has been partially restored by the Renaissance du Chatelas de Grospierres association.
The Font Vive spring is a resurgence like the Fontaine-de-Vaucluse. Information about its exploration can be found on this website

A very beautiful hike, with clear explanations and a well-marked route. Along the way, you will discover the ruined village of Chastelas, a mysterious place frozen in time, and the Font Vive spring with its green waters, which is well worth a detour!
Thank you to the author for this beautiful hike!

Very beautiful route, but avoid when it has rained. The ford between points 13 and 14 was impossible to cross due to strong currents. The detour was less enjoyable.
Between points 6 and 7, you could go via Puy Lacher, which is even more beautiful. That would make the hike difficult.
Otherwise, very good

15 to 16 km is a good length for a hike, especially when there are points of interest along the way that invite you to linger and explore. What's more, the GPS will guide you there without any hassle.

Superb, easy and varied hike, starting in the heath, climbing under holm oaks and returning via some superb points of interest: viewpoint, chapel, abandoned village, resurgence and river.
GPS is essential, as there are only markings at the end. From point 6, we went left via the summit of Puy Lacher before rejoining the trail at point 7. A very interesting alternative route.

Thank you for your comment.
As for the ford, after crossing it myself three weeks ago, I had actually modified the description and the route to avoid this point, which now seems to be more or less blocked. It's a shame you didn't see the latest version.

A beautiful hike in the Ardèche region in a lovely setting with stunning panoramic views. Two springs and a resurgence.
A ruined castle. Paths and trails beginning to bloom (early spring). The Notre Dame chapel is a place to reflect. After point 14, we had to use bin bags to keep our feet dry when crossing the stream (the ford was submerged).
We highly recommend this beautiful hike.

A beautiful walk. Beautiful scenery. The Pic de Larcher is a great place to stop for lunch, with Mont Ventoux on one side and Pic St Loup on the other.
The chapel and abandoned village are currently being restored by an association. I highly recommend this hike.

an interesting route, but it lacks viewpoints and, apart from the ruins of Chastelas and the Font Vive spring, it is somewhat uniform, although this is compensated for by a very pleasant smell of tin.

A pleasant hike with the discovery of the Notre-Dame des Songes chapel and the resurgence of the Font Vive spring!
We made a detour via Puy Lacher, which, given the descent, is only of moderate interest, but a return trip to the orientation table is an interesting alternative.

beautiful route through the hills. We passed by Puy Lacher; the climb and descent have a few steep sections but are not dangerous. The view from the top is magnificent. The Font Vive resurgence is a magical place and the abandoned village is very interesting. We did the hike with GPS; the route is very accurate. Thank you to the author of this hike
