Description of the walk

Start from the Étang des Karuns car park.

(S/E) Take the path towards the forest, heading north-west.

(1) Join theGRP® Sèvre et Maine (yellow and red markings) which runs alongside a campsite. Cross a road with a cross and head for the Château de la Barbinière.

(2) At the castle, turn left and cross the railway line. Turn left about 500 metres further on and continue, leaving the access road to La Guérivère on your left. Pass under the A87 motorway and head towards the banks of the Sèvre Nantaise. Cross a stream and reach a road.

(3) Follow it to the right to reach Moulin Guy.

(4) Cross the river again and continue along the path that turns right and goes up to the Route du Plessis cross.

(5) Turn right, reach the railway line and follow it on the right

(6) At the end of the bend, leave the road and take the path on the left that winds towards the Sèvre Nantaise. Turn sharply left, pass under the motorway and then under the Barbin Viaduct and join the river.

(7) Continue straight ahead to follow the Sèvre Nantaise.

(8) In the left-hand bend after the place called Le Domaine, turn right and head towards Buchet.

(9) Turn right to take the ford and follow the path to the footbridge. Cross it, continue straight ahead and go up to the road, which you cross. Almost opposite, take the path that leads back to the car park, following L'Étang des Karuns (S/E).

A lovely hike, though the signposting could do with some improvement, particularly where you have to leave the red and yellow markings

Very pleasant route. We walked down the steps of the viaduct and the slope is quite steep . Perhaps it would be a good idea to install safety railings on one side or the other for the safety of walkers.
Otherwise, we recommend it. The site is very pretty.

  • A varied and slightly hilly route. Numerous bridges, paths and other passages along the river remind us of low-altitude mountain hikes. A beautiful route for hikers and runners like me who love nature and peace and quiet. The passage over and under the viaduct adds a special touch to this beautiful route.

A very beautiful hike. But be warned, the last third of the hike after the viaduct is quite challenging. There are many steep sections over stones and roots.

beautiful hike, the only downside was when we arrived at the foot of the viaduct, we had to go down the steps and walk along the Sèvre (this isn't mentioned in the description but it's very pleasant when the weather is dry).

superb walk, but the signposting needs improving, as many paths cross each other.

Hello everyone, a beautiful hike along the Sèvres River and the Vendée countryside.
I highly recommend it. And the viaduct is a must-see 💖
