This wetland area is a birdwatching paradise about 10 kilometres south-east of Hossegor. With a surface area of about 1,000 hectares (just under 2,500 acres) it is the last big protected wetland area on the Aquitaine coast.
The southern part, the Marais sud, is open to the public and visitors can enjoy the wildlife and plants during a 5 km walk. Head for the Parking area at the Maison du Marais off the D 71.
