The Monkey Bike Bar is a must-see place (Bar) on the Nantes-Brest canal! ideally located on the port of Blain with a terrace to quench your thirst with a nice view!

These old windmills are the best proof that humans were clever enough to harness the power of the wind for a number of centuries - long before the discovery of electricity and the inventions that followed. So what is celebrated today as modern (so-called green or renewable) energy is basically old hat in a new guise.

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.

Artificial, the lake hosts many activities on its shores: a swimming pool, a campsite, a leisure park, a golf course and a hotel-restaurant.
