The Lignon Valley between Jaujac and La Souche

Between Jaujac and La Souche, the Lignon valley is an open valley, dominated to the north by the Rocher du Midi and to the south by the Tanargue massif. The hike takes you along the left bank, where you can admire old buildings and walk along beautiful, pleasant paths dotted with old bridges crossing streams, then back along the right bank and a succession of old hamlets.

Description of the walk

Park near the main square in Jaujac.

(S/E) Cross the square, take the passage between the houses (Tourist Office), follow the street to the right to reach the Pont du Chastelas. On the way there, the yellow and white markings are still clearly visible.

(1) From the bridge, admire the old village of Chastelas and, downstream, the beginning of the basalt flows from the Jaujac volcano. Take the road to the left of the bridge and then, a few metres further on, the path on the left that descends towards the Lignon.

(2) Walk past an old silk mill, where the mechanism that transmitted the rotational movement is still visible at ground level. The path follows the old water supply pipe.

(3) You will arrive at a large square building that was once an oil mill. Cross the bridge and climb through a wood to the Château du Bruget. Before the château, descend slightly to the left to pass below the building, then climb up through the holm oaks and join a road.

(4) Follow the road to the left. After 100 metres, take the road on the left. Pass another crossroads.

(5) At the next crossroads, take the path on the left which passes through Brunissard, then Peyreplane, continuing to follow the markings. You will come to a crossroads with some very beautiful paths lined with old walls.

(6) Follow the path downhill to the left.

(7) Join the road and follow it again to the right. At Dabrigeon, take a path on the left and cross a superb old bridge over a beautiful stream.

(8) Continue to the left of the bridge, then the path veers to the right to follow the Lignon. A little further on, on the left, there is an arch from a bridge that was washed away by the river.

(9) At Lioure, join the road that leads to La Souche, crossing the bridge over the Lignon.

(10) After the bridge, cross the D19 and take the first path on the left, called Chemin des Endettés. Follow it straight ahead to the Château de Charay (or Charrail).

(11) Join the D19, follow it carefully for 100 metres to the right, take a path on the right between the walls, join a tarmac road, follow it to the left to join the D19. Follow it again for 350 metres to the right.

(12) After La Croze, take the path on the right to the hamlet of Les Peyreyres. Continue straight ahead on the road after Les Peyreyres for 200 metres.

(13) Take the shortcut on the left that cuts across the hairpin bend. Continue down the Peyreyres road, passing close to the hamlet of Basses Peyreyres, and cross the Peyreyres stream via the bridge.

(14) Just after a new bridge over the Ruisseau de Sarrayou, turn right onto the path that climbs into the forest. Pass two hairpin bends, then a barn on the right. Be careful, this is where people get lost, as there are hardly any markings. Look for the path that climbs steeply to the right. If you reach a three-way junction, you have gone too far.

(15) Climb the steep path to the D5 (Col de la Croix de Millet road), follow it to the right for about 50 metres, then take the small road on the left towards Cheylas. Before the hamlet, take the path on the left towards Fougeyrolles, descend again on the left via the small road that rejoins the D5, which you follow this time to the right downhill to La Mercerie.

(16) At the La Mercerie crossroads, leave the D5 on the left, cross the hamlet and descend along a path to a small road, which you follow to the right. Keep left at the next crossroads, then go straight on to reach the stream and then the D19 via the path between the houses.

(17) Follow the D19, which can be very busy in season, with caution, to reach Jaujac and the starting point (S/E).

Notes

Fountains and springs are marked on the IGN map, but there is no guarantee that the water is drinkable. It is wise to bring water with you. Wear good walking shoes, as there are good paths, but some tricky sections on the way back.

Worth a visit

(1) If you have time, you can climb to the top of the old village of Chastelas to visit it and reach the ruins of the old keep.

Alternative route for about 500 m: About 20 metres after (4), take a path on the right which continues along a small road that joins the previous route, which you then take on the right.

When you reach La Souche, you can take a detour along the main road to the church square. The village comes alive in season (summer, holiday periods).

(14) If you are tired, you can shorten the hike by continuing straight ahead to join the D19, which you follow to Jaujac. However, be aware that there are still a good two kilometres of road ahead, and the D19 can be very busy.

(15) If you take a wrong turn at this junction and do not wish to turn back, you can keep left at the three-way junction and join the D19 as described above.

A beautiful hike with some interesting sections. However, there are many paved roads (between 4 and 6 and between 9 and 12).
As you approach point 4, the estate is private; once we had passed the estate below, we lost the path. Part of the path seems to have been taken over by the estate.

A largely shaded route that we completed entirely on a very hot day. As a result, we didn't encounter any other hikers!
I strongly advise against crossing under the road at a place called "Brunissart" (between points 5 and 6). It is better to stay on the road. The owner of the farm below has put sheep there, accompanied by a very intimidating guard dog.
There are many pleasant places to stop for a picnic.
It is not easy to map out a route in this region.
I would therefore like to thank the author for this fine work.

PS: I love the Ardèche, but I know that routes often have to be adapted there.

I found this hike very enjoyable, not too steep... however, it was poorly marked in places, so I had to use my GPS.
There was more road than in the other hikes I did that week, but the proximity of the river was very pleasant.
Arriving in Jaujac and having a beer at the pub on the square was also very nice!

Nice on the Jaujac side at La Souche, but the return journey is quite long! End of hike.

A beautiful hike with stunning scenery, passing through charming little hamlets.
The signposting is average at the start between Jaujac and La Souche, but well marked thereafter.
Following the Lignon river and paying close attention to the small paths, you can find yourself at the water's edge in magical little spots.

I only did the walk from La Souche lake to Jaujac in the opposite direction: swimming at the start and finish and a lovely walk, but on the road nonetheless, although it was very quiet.
With the family: I approve!!!

This part of the Ardèche is as beautiful and pleasant as ever. There are some very lovely paved slanting streets to explore.

Hello everyone, a beautiful hike without any major difficulties. The vegetation changes from holm oaks to chestnut trees, and the view of the Ardèche mountains is magnificent. The only downside is that the route often follows small tarmac roads that connect the various hamlets, but fortunately there is no traffic. I invite you to give it a try.

The only slight difficulty is finding the path that descends from point 6.

A beautiful discovery of the Lignon valley, stone hamlets and chestnut trees.

A pleasant route; on the way there, very few markings; on the way back, markings that are useless, which you only discover once you've finished the section. In short, don't count on them! A few problems at La Mercerie and afterwards, due to a lack of markings... so a few steps for nothing...!Otherwise, just the right amount of time... not too hot, even cool; remote hamlets, beautiful paths... nice! Thank you (I did this route more than 10 years ago...!)
