포르생페르‬에서 가장 멋진 ‪4‬개의 천연기념물

The largest natural plain lake and the second largest ornithological reserve in France, Lake Grand-Lieu offers magnificent lakeside landscapes. Here, you have to get off your bike to get as close as possible to its waters.

Magnificent view of the lake 👌

Former limestone quarry now transformed into a protected natural area with a pond in the northern part and a wetland in the southern part. Important birdlife. The paths and trails are well maintained, mainly for mountain biking and gravel.

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

I couldn't shake the stone, but you can try :-) Peaceful site on the banks of the Acheneau River. Wet in wet weather.

Always accessible from the town of Cheix-en-Retz. But be careful, the next part of the circuit can be flooded in winter.

Not found where to go up to make it move, but I'll try another time :-)

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.
