Etang de Roche Ballue

Highlight • Lake

Located in a beautiful natural site, this pond, in fact an old quarry filled with water, is open for swimming.
Be careful, beyond the buoys, the pond becomes very deep and therefore dangerous. It is therefore necessary to supervise the children.
There are also children's games, picnic tables and a bicross field on site.
NB: entry is payable in summer (with supervised swimming).
Apart from the road, several options of paths to get there or from there:
The Chemin des Foulques allows you to continue along the slopes towards La Montagne, for fairly committed cycling and passages that will require you to dismount.
The path of the Estacade which goes towards the Loire (cul-de-sac) offers several observation posts of the wetlands and their avian fauna.
The Chemin de la Mandrine links with the Port Lavigne shipyard and the statues of animals perched in the trees.
Finally, the Chemin de la Sangle goes towards Bouguenais. Nice, but you have to climb a long and steep staircase, so not at all compatible with heavy bikes or panniers.

Shaded walking path, accessible to all, along the marshes of Lake Gd Lieu.
At the end, Coté St Aignan, you absolutely must continue to the equally unmissable site of "Pierre Aigüe" in order to admire the most beautiful view of the Lake and its environment.
