Not necessarily the most suitable beach for swimming, but the view of the rocks and the bouchots is worth the trip.

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.

Impressive dolmen. You will find a second dolmen a few dozen meters further, but this one has fallen to the ground.
