Popular around Marais indivis de Grande Brière Mottière
The Lac de la Vallée Mabille, or Lac de Savenay, is a beautiful artificial reservoir that is worth a small detour. By bike, you can easily cycle around the southern part (south of the road) via a wide and well-maintained wooded path. On the other hand, the northern part, wilder and quite rugged, is more suited for hiking than cycling. Crossing at the level of the dam is possible thanks to a footbridge.
