Discover a rare ecosystem made up of multiple habitats: aquatic area, wet moors, peat bogs, reed beds, wet meadows.

In spring and autumn, birdwatching and photography enthusiasts come to admire populations of migratory birds stopping on the lake.

This site, nicknamed "the Landes Amazon", is classified as a nature reserve and offers visitors trails through lush vegetation. Visit the Maison de la Réserve on the banks of the lake for an educational discovery of local biodiversity. Embark on a “galup” (traditional flat-bottomed boat) and let yourself be guided by the boatmen through 10km of wild landscapes, between marshes, dunes and peat bogs. An unforgettable excursion to experience with family, friends or lovers!
