La Voute car park.
(S/E) Follow the right bank of the harbour to the rock, then turn right and follow the banks of the Vilaine to the square before the shipyard.
(1) Once past the children’s playground, cross the car park and take the path that leads under the chestnut trees. A few metres further on, climb the embankment supporting the road, go past the end of the parapet, cross the road, and continue along the path that climbs up the opposite slope.
Follow this path for about a hundred metres, then walk alongside the road that passes under the cable-stayed bridge. At the crash barriers, take the track that has been laid out behind them and turn left onto the first path leading down from the road embankment. It runs along the riverbank, like a balcony above the river, as far as Ville Izac.
(2) In the village, turn left onto the path leading down into the valley. At the bottom, turn right and head back up towards the road leading to the Moulin de Bourigan. At the road, turn right, then right again at the next junction. Turn left at the next junction, and passing in front of the Croix Neuve campsite, join the RD176.
Turn right for a few dozen metres, then left towards Ville ès Loups, then Ville au Moguer.
(3) Cross the D4, turn right then left eighty metres further on and continue along the road that crosses the ZA des Métairies industrial estate. This road has a straight section and a large bend. At the next bend, turn left onto the path leading down towards the Étang du Rodoir, and head towards the edge of the pond’s dam.
(4) Cross the D765 and follow it to the left for about 350 metres. The verges are wide, but there can be heavy traffic on this road. Caution and care are advised.
Before the wine cellar, take the path that climbs the hillside, via the old right-of-way of the ‘Morbihan narrow-gauge railway’. At the first house, turn 180° to take the path leading to the top of the plateau. Rue de la Bonne Fontaine takes you to the heart of the village of La Ville Renaud.
(5) In the centre of the village, turn left onto Rue des Saulniers, then right onto Rue de la Grée du Puits. You will then reach the village of La Châtaignière. In the centre of the village, turn right between the houses and head into the farmland until you reach the edge of the woods. At the trees, take the path branching off to the left. It winds through the woods along a lovely route offering fine views towards the town of La Roche-Bernard, beyond the Rodoir valley. At the next path, turn left and head back towards the village, then right towards the D34.
(6) Cross the road, turn left for a few metres then right onto Chemin des Vergers, which leads to the heart of the village of La Grée. Continue by turning right then left through the houses, and join Route du Rosquet.
(7) Follow this road for just under a hundred metres, then turn right onto the farm track separating two plots. Follow it down to the woods, then continue along the pleasant, steep path that leads to the banks of the Vilaine. Then head to the port of La Roche-Bernard by following the path along the riverbank. The end of the route has been laid out as close as possible to the water on the left bank of the harbour. This very natural stretch offers fine views of the ships moored there and the old buildings at the far end of the harbour. This path leads to the Voûte car park (S/E).
Note: During very wet weather, the riverside path may unfortunately be impassable. In this case, return to the point (7) and take the small road (Rue du Port) back to the starting point, the Voûte car park (S/E).
