On the left of the trail, do not miss the viewpoint of the viaduct. Stay on the same trail until you reach the road. Take the path that runs alongside it on the left. At the fork, continue straight on the grassy path. Go around the playgrounds on the left to reach the library. Take the street on your right. Photo credit: Emmanuel Berthier

This path borders the Gouët river, which meanders along the mossy rocks, giving to see magical landscapes. If it has rained recently, the path will be muddy. It is therefore necessary to provide appropriate equipment: boots, walking sticks...

From the dam you have a great view over the lake and into the valley of the Gouet. You can start great tours around the lake from the nearby hiking car park (up to 2.00 m)!
