Rochetaillé - Dams, Gouffre d'Enfer and Pas du Riot

The Gouffre d'Enfer dam is one of the most famous sites in the Rhône-Alpes region and a popular walk in the Saint-Étienne area. It was built in 1860 in the Furan valley, near Rochetaillé, and completed 17 years later by the Pas du Riot dam. We then continue along the dam trail to the Pont de Souvignet. The return journey takes us via Les Palais, Les Sagnes and La Croix de Givet before joining theGR®42to arrive at Le Plateau and Rochetaillé.

Description of the walk

Departure from the car park below Rochetaillé Castle.

(S/E) Return to the castle, cross the D8 (Rue du Parc).

(1) Take the steps down to Rue de la Roche Corbière. Turn left towards Roche Corbière and follow the road for 500 metres.

(2) Turn left onto the Chemin du Tour du Parc until you reach Roche Corbière. Join a small road and follow it straight ahead until you reach the Gouffre d'Enfer dam.

(3) From there, you can climb up to the right to the viewpoint overlooking the Furan Valley. Set off again, following the lake on your left.

(4) Cross the stream towards the Pas du Riot dam. Take the path up to the top of the dam. From there, you can admire the valley below and the Pas du Riot lake opposite.
Set off again on the road on the right, following the lake. Go around the mouth of the Barbarie stream and cross the bridge of the same name. Leave the road and turn right to continue along the lake shore. Continue to the end and you will reach the Lerque de Biez.

(5) Continue straight ahead along the Sentier des Barrages in the Furan valley until you reach the Pont de Souvignet car park. Cross the D37 (Route du Pont Souvignet), turn right and cross the Furan to reach the pumping station.

(6) Turn left onto the path that runs alongside the Furan. Stay on the Route Balay without crossing the stream for about 800 metres. Leave the Route du Comte Amelot on your right and continue on the Route Balay, crossing the Furan twice until you reach the crossroads.

(7) Turn left along the Furan and cross the stream a third time towards Les Palais. The path joins Route Godemard. Turn right towards Les Palais without detouring via Le Bessat.

(8) At the wash house, continue straight ahead for 150 to 200 metres.

(9) Turn left onto Route des Sagnes. After about 500 metres, at the pumping station, turn right onto Chemin de la Croix de Givet.

(10). When you reach the cross, cross the D8 (Route du Bessat) and take the path parallel to the departmental road to join theGR®42

(11) Turn left and walk straight ahead to the hamlet of Le Plateau.

(12) Cross the hamlet and continue straight ahead, ignoring a path on your right, until you reach La Violette.

(13) Continue straight ahead through La Driguière and Charteloup. After the hamlet, continue along the path. Be careful, the descent is steep and can be slippery.
When you reach Rochetaillé, turn right to return to the car park (S/E).

A beautiful route, especially the first part with the dams and the end with its stunning views.
We found the section between 5 and 6 rather boring (a wide forest track with a few bikes). If we were to do it again, we would cut it short at around 5.
It was a bit crowded around the dams on a Saturday morning.
Also worth noting are a few climbing spots at the beginning.

We weren't disappointed by this beautiful hike. The scenery is magnificent and following the Furan river for much of the way is very pleasant.
There were no particular difficulties on the route, except near the dam at Pas du Rio, where we took a wrong turn. When you get close to the dam, make sure you take the path that goes up to the right, as we ended up in front of an iron gate at the foot of the dam.
There were very few people on the trail, but it was a Friday, so we were surprised not to see anyone else in such beautiful surroundings.
Thank you to the author for this lovely walk.

A very beautiful route, in my opinion. Some stunning views, especially at the beginning. The forest is cool and pleasant when it's hot. I would recommend this route.

A very pleasant day trip between dams, forests and flower-filled highland meadows. There is little elevation gain, but the length of the walk may discourage younger children. We completed the circuit in 5 hours, stopping for a picnic and walking at a good pace. Bring plenty of water and full hiking gear.

Very beautiful hike, but after the Souvignet bridge, the signposting (sorry to mention it) to get back to Les Palais is not marked on the path and is quite far inland, which makes for a longer hike.
Worth doing again
