A few kilometers south of Chatelaillon, it reveals itself between sea and marsh to the most curious of adventurers. Let yourself be guided by the guardian of the place Jean-Paul and discover a territory of preserved beauty.

A visit that must be earned!

Like everything else that is precious, access to the Marais d’Yve must be earned. Everyone by car, or even better by bike, along the D137. Direction the Nature Center ! The access to the nature reserve being regulated, it is the starting point of all visits on the site. We pass through the door like a border between civilization and the wild world while Jean-Paul welcomes us.

The reserve is his domain! Once its operation is explained, we take the time to admire nature from the Center’s large bay window. We still can’t believe how close we are to Chatelaillon, yet so far from everyday life…

Adventure doesn’t wait! Jean-Paul offers us 6 different activities to discover all the facets of the Yves Marsh Nature Reserve.
