Description of the walk

(S/E) From the Salle Jules Ferry, head towards the Route de Redon, cross it and take the road (Route du Chandelier) opposite, running alongside the community hall. Continue along Rue de l’Abbé Monneraye. At the end, turn left, then left again towards Le Cas and the sewage treatment works.

(1) At the wastewater treatment plant, take the small path on the right and continue alongside the plant until you reach a wider track. Carry on until you reach a road.

(2) First turn left then right onto a cul-de-sac which leads onto a track. At the end, facing a stream, turn left until you reach the Marais de Coinanton junction.

(3) Turn left onto the path that passes under a power line; at the crossroads, turn right onto the road towards the hamlet of Les Bois. At the first road, turn right towards La Vacherie.

(4) In this hamlet, take the road on the left between the houses and walk a few hundred metres to reach the first pylon.

(5) At the pylon, enter the woods, take the path on the right and, a few metres further on, take a second path on the right which runs alongside the woods. At the second pylon, take the path on the left which leads into the woods and continue until you reach a road.

(6) Follow it to the right and, at the end of the road, turn left towards the Route de Redon (D764). Cross it carefully and head up to La Grée des Moulins.

(7) Take the path opposite; continue along it, ignoring the small paths on the left, and stay firmly on the main path as you head downhill, where you’ll walk alongside a mountain-bike track.

(8) When you reach the fountain, turn left onto the path that runs alongside the road and rejoin the road after a few hundred metres to emerge at the banks of the Oust.

(9) Turn left, following the River Oust towards the Potinais Dam.

(10) At the dam, follow the towpath to the Ti Kendalc’h descent. Before the descent, cross a small bridge (landmark).

(11) Turn left up the hill towards Ti Kendacl’h, cross the site keeping slightly to the right and continue straight on until you reach the entrance to Saint-Vincent-sur-Oust.

(12) At the entrance, turn left into the first street, then right, and finally left towards the Salle Jules Ferry (S/E).

Hello, there’s just a mistake at waypoint number two: it should read ‘first turn left then right’.
