La Grande Brière
In this, the second largest area of marshland in France after the Camargue, canals and aquatic plants stretch as far as the eye can see. It occupies 7 700 of the 40 000ha of the Regional Park of Brière, which lies just north of the Loire Estuary. In this protected area, a few minutes from the beaches of La Baule, you can make your way around on foot, on horseback, or even in a barge, and you will have the opportunity to observe the greatest concentration of harrier birds and grey herons in France. Don't miss the marshy prairies of Fedrun Island and the thatched cottages of the hamlet of Kerhinet.
