The Marais de Castélou is located in the heart of the Narbonnais Marshes and part of the Parc naturel régional de la Narbonnaise en Méditerranée. On the eastern part of Marais de Castélou you see grazing horses and bulls. To the west and south are the wild areas: the sansouires, salt meadows, and reed beds occupy vast areas more or less intertwined. Many birds come to nest, overwinter, hunt or simply to a migratory stop on the site. These include White Stork, Black Kite, Purple Heron, Purple Swamphen, Penduline Tit, Great Reed Warbler, Moustached Warbler, Squacco Heron, Black-winged Stilt and many other waders who take advantage of the submerged plots to become dry.
By car, take the road to Lunes, towards Gruissan, south of the city.
