Étang de la Barrière

Along the Étang de la Barrière, in French Cul-de-Sac, a 225-meter-long wooden path on stilts allows the discovery of a fascinating ecosystem between the land and the sea. Dominated by mangroves, this is a popular spot for numerous species of bird both local and migratory, particularly those that thrive in wetlands, such as Ruddy Turnstones, Greater and Lesser Yellowlegs and species of egrets, sandpipers, and plovers.
