Very beautiful place. I was able to cycle around the lake but I'm pretty sure many of the paths are impassable in winter.

The Provostière pond, with a surface area of 73 ha, is connected to the Vioreau lake by the Rigole des Ajaux. This complex is part of the supply system of the Nantes-Brest canal. Its hydraulic management is ensured by the Loire-Atlantique Department, which has owned it since 2008. A 5.5 km path on which a bird observatory is located allows you to go around the pond in about 1h30.

What we'd heard about Brittany was that it's supposed to have lots of forests, a special kind of people, and nature beyond nature. But we weren't expecting such a beautiful little town, and as for the special Bretons – they're just super friendly!
