This is the starting point for exploring the unique landscape along the Courant d'Huchet River. Either on foot along the trails or by boat (recommended). Absolutely unique; you feel like you're in the Amazon region and, ultimately, on the Nile.

We have been to the area twice by road bike, once coming from the east and once from the north, and it is always worth it.

Partially classified as a nature reserve and Natura 2000 site, Lake Léon is very popular with nature lovers. Discover a rare ecosystem made up of multiple habitats: aquatic area, wet moors, peat bogs, reed beds, wet meadows. The lake is home to a great diversity of fauna and flora: mammals such as the otter, the coypu or the European mink, many insects and birds such as the grey heron, reptiles such as the European pond turtle, commonly called the marsh turtle. In spring and autumn, birdwatching and photography enthusiasts come to admire populations of migratory birds stopping on the lake. To the west of the lake, the Courant d'Huchet meanders over more than 600 hectares to the Atlantic Ocean. 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!
