A short, easy walk in the hills above the village, passing a rock shelter used in the Neolithic period and a spring halfway along the route. At the end of the route, you can see the domes of the observatory.

Description of the walk

The starting point is near the Croix du Chêne, on the edge of the D5 between Saint-Michel and Aubenas. Leave the road and take the track, passing the small tarmac road called Chemin du Farnet on your left, and park a few metres further on in an open space.

(S/E) Follow the track to the left, which becomes a path after the first kilometre and leads to the edge of a lavender field where there is a survey marker.

(1) A few metres further on, the path continues through the forest, still on the plateau, running along the slope above the Largue plain. Keep heading north to reach the Jas de Savy, now in ruins, of which only sections of ivy-covered walls remain.

(2) Continue straight on to reach the prehistoric cave: it is actually more of a rock shelter. A passage allows you to descend beneath the rocky outcrop a few dozen metres south of the shelter. After this, follow the foot of the outcrop northwards and take a path that leads back up to the main track.

(4) Leave the edge of the plateau and turn onto the track on the right. At the three-way junction (elevation 740), head down to the left towards the spring, which is just beyond a shelter with a tin roof, amongst the rocks to the left of the path.

(5) Continue on to reach the bottom of the Ravin de l'Été.

(6) Turn right to follow the stream on the left bank.

(7) Cross the stream to climb up the other side of the ravine. Once on the plateau, the path runs more or less alongside a track on the right-hand side before eventually joining it.

(8) Turn left to reach the junction at the hamlet of Les Eyssarts.

(9) Turn right to join the main track and head straight on to the car park (S/E).

Notes

The paths wind through a sparse forest of small oak trees that provide little shade. The spring is flowing well at the start of November, but what about in summer?
The route does not follow the marked paths, except for the last 500 metres. There are numerous junctions between tracks and paths; follow the suggested route.
I set off to look for drystone shelters, but I didn’t see a single one, nor any of the masks for that matter.

Worth a visit

(3) Le Jas de Savy: the only structure spotted along the route, apart from the low walls and piles of stones.
(4) The rock shelter, used in the Neolithic period. Unfortunately cluttered with more contemporary objects.
(5) The spring: halfway along the route, near a shelter with a tin roof, it is flowing in early November.

A lovely walk: varied, picturesque, mostly shaded, and very peaceful (you soon stop hearing the road).
The walk winds around quite a bit to avoid the track (which is less pleasant). The cave is well worth the ‘detour’.
But keep a close eye on the route on your mobile.

A very beautiful walk, but you need to check your route from time to time on Visorando, as there are no markings on the ground.

A lovely route, mostly through woodland, but with a few clearings and beautiful views. The paths between the DFCI firebreak and single tracks are relatively easy to see. A GPS device is a useful addition.

A pleasant little walk to explore the local countryside and a series of rock shelters.
Well worth a visit if you’re on holiday in the area.
Don’t forget to visit the old village of St Michel.
No problem following the route with GPS.

Thank you for this lovely walk. We extended it by an hour and a half (there and back) by setting off from St Michel along a pretty path. We didn’t see a soul along the route.
A GPS is almost essential as numerous paths and tracks cross the trail and it isn’t always obvious (particularly between 6 and 8)
We did the walk at the end of June; the blue lavender fields blending with the yellow dandelions were superb.
The spring (point 4) still had water. A delight in the heat. The stream, however, was of course dry.
Plenty of shade from the oak trees and numerous spots for a picnic in the shade.
Well done, Jeff
