A unique feature of the region, the Marais Poitevin is an ecological treasure trove and a feast for the eyes. A succession of painters' pictures awaits you on your walks. You can visit on foot or by bike, but for total immersion, nothing beats a boat trip. Situated between the departments of Vendée, Charente-Maritime and Deux-Sèvres, the Marais Poitevin is nicknamed the Green Venice. A succession of green canals covered in duckweed are the source of its charm and uniqueness.
