Arriving from La Chevroliere in the direction of Pont Saint Martin, turn off to cross the Ognon with the Bac in spring and summer, it's more pleasant

At the end of a long straight line on which you can test your speed is one of the most beautiful spots to admire the Goulaine marsh.

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.
