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.

Church from the late 19th century. The (small) town center of Malville is quite cute and well-maintained. Few shops, but there are toilets.

The Lac de la Vallée Mabille is an ideal place to run. The tracks are impeccable thanks in particular to the GR3 which runs along its banks.
