Small beach on Lake Vioreau. Numerous picnic tables in the shade of the trees. Restrooms with drinking water taps. An ideal spot for a break.

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 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.

This beautiful pond, fed by the Janneau stream, is unfortunately private and off-limits to the public. It can be seen from the D14.

A perfect place to relax or have a picnic. You can cross the Erdre River to take a path opposite.

This archway is accessible, but the following ones toward Nort-sur-Erdre are not, due to ongoing safety work. A beautiful spot down below for a picnic on the banks of the Erdre.
