Mabille Valley Lake

Highlight • Lake

Lac de la Vallée Mabille, more commonly known as Lac de Savenay, is a beautiful body of water located at the eastern entrance to the town of Savenay. Artificial, the lake hosts many activities on its shores: a swimming pool, a campsite, a leisure park, a golf course and a hotel-restaurant.

Very famous among the locals, this little green setting is also a delight for long-distance hikers. Indeed, the iconic GR 3 meanders along its banks.
