Le Courant d'Huchet is a stream 10 km long joining the Lac de Léon to the Atlantic Ocean. It was disovered by Gabrielle d'Anunzio, when she passed by the Landes in 1908. About 1920, Maurice Martin, Rosny Jeune and Loys Labèque made it known troughout France. It was classified in 1932 and established as a "naure reserve " in 1981.

Past the lake, where you find the last yellow water lilies, you get to a zone of great botanical diversity, that's where we find the royal "osmonde" and the "karebs" (used by the olders in the past for making chair bottoms), the sagittarius and others species.

Past the dam, which is a lovely fish pool excellent fishing spot in winter, you enter the deep wilderness  of the courant d'huchet, where the forest is untouched and boatmen have difficulties passing because of its narrow passage. There we find pink hibiscus and cypress pine, whose roots protude in winter, when the trees have lost their leaves.
