The west bridge of Lake Voireau offers a beautiful, unobstructed view of the reservoir. The largest body of water in Loire-Atlantique, this lake stretches through the heart of the forest. Its wooded banks and landscaped beaches make it a pleasant stopover for a nature break or a swim.

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.
