The most touristic of the eight islands that make up the commune of Saint-Joachim, notably for its famous thatched cottages typical of Brière and its Michelin-starred restaurant, La Mare aux Oiseaux.

Superb viewpoint from its summit, on a clear day you can see the Saint Nazaire bridge and the surrounding marshes. However, be careful when climbing wooden steps in wet weather with cleats and road shoes.

Tower rocks a bit. Good for getting an overview of the area. If you're already there, go up, otherwise you don't have to travel extra.
