Circuit de Trévineuc

Le port de Foleux marque la limite occidentale des marais de Redon. À cet endroit, la Vilaine se resserre et se fraie un passage entre les reliefs du Sillon de Bretagne. Le circuit proposé permet de découvrir la rive Sud de ce goulet. Il parcourt le bord de l'eau et joue aux montagnes russes à travers le relief assez accidenté de Nivillac.

Description of the walk

Park near the shipyards at Port de Foleux, on the left bank.

(S/E) From the car park by the water's edge, return to the road you arrived on and take the path on the left when you reach the first houses. Climb the steep slope and pass the first hill.

(1) Turn left into the woods about 50 metres after the fence of the last property on the left. Follow the edge of the woods, staying under cover, and go around the left side of the sewage treatment plant basins. When you reach the overlook above the port, follow the path to the right that winds along the top of the slope. Passing from the edge of the plateau to the thalwegs that cut into the hillside, continue until you reach the track that climbs up from the river banks. Turn right to leave the woods.

(2) Shortly after leaving the woods, take the path on the left that winds through the woods again.

(3) Below Trévineuc, turn left to descend towards La Vilaine. At the river, turn right and follow the bank to a small cove. In winter, this passage may be more or less flooded.

(4) Then leave the water's edge and take the path that climbs through the woods to the road. Cross it and continue to the right for a few dozen metres, before turning left to follow the path that climbs up the side of the valley, along the fence of the Domaine du Roffo

(5) During this wooded section, you can see the unusual accommodation (tree houses) available here. At the bottom of this valley is a rock shelter where traces of prehistoric habitation have been discovered. When you reach a wide, straight path, turn left and follow it uphill to reach the plateau (La Grée) between Baragan and Bringuin

(6). Take the road on the right to the first village, then turn right at the second crossroads.

(7) In the centre of the village of Baragan, leave the road that climbs to the left and take the farm track slightly to the right. Continue downhill to the edge of the woods, then turn left and enter the woods. The route then follows a path that climbs up the hillside.

(8) At Guervinan, descend to the right, at the bottom of the valley, cross the stream on the metal footbridge and climb up the opposite slope, going around the hill, until you reach the Trévineuc road. Cross it and follow the path opposite, which will take you back to the farmland on the plateau. The path leads to a farm track. At the end of this track, on the road, turn left through La Grée de Cassan.

(9) At the first houses, turn right and cross the village of Cassan. At the last farmhouse, turn right at the shed onto the path that leads to the Vilaine. After 150 metres, take the path on the left and follow it until you reach the road to the port, passing behind the houses that line the road to Foleux.

(1) Then turn right to return to your starting point (S/E).

Practical information

Toilets are available at the port of Foleux.
For part of the year, there is a way to cross the Vilaine River by boat to reach the opposite bank where the Foleux bar-restaurant (in Béganne) is located.
During rainy periods, the section along the Vilaine river, before point (4), can be very wet or even temporarily flooded. It is therefore advisable to do this route in dry weather.

Au retour, un arrêt à la Roche-Bernard, petite cité de caractère, s'impose.

A beautiful, hilly route through the woods, with superb views of the Vilaine river. We didn't encounter any particular difficulties, but some sections are likely to be very wet or even flooded during rainy periods.

Indeed, I think you must have got your feet wet along the Vilaine!
Have a good evening

Do this if it has not rained beforehand, as some areas are prone to flooding!

Hello,

Just a few comments about this bucolic route:
- this route is best enjoyed in dry weather, as the banks of the Vilaine are very wet at the moment, due to the heavy rainfall in recent days.
- as bubble no. 6 is located in the village, it is a little difficult to find the right direction. Faced with two paths supposedly leading to the Vilaine, our first choice was not the right one and ended up in a field.

I would gladly recommend this hilly and multifaceted route to my hiking friends (landscape, architecture, etc.)
Thank you to Philrandovilaine for allowing us to discover this beautiful corner of southern Brittany.

I am delighted that this walk allowed you to have a good time.
There are others along the Vilaine, both to the north and south, which I have tried to describe with the same desire to share the pleasure of walking there.

Hello
A lovely little Sunday walk under slightly grey skies. Diverse landscapes along the Vilaine river, woods, farmland, a few hills to break up the monotony – in short, a good Sunday. A word of advice: after rain, it's best to wear high-top shoes as the banks of the Vilaine are a little damp, but nothing insurmountable.
Thank you, Philorandovilaine.
