The 'Green Venice' nickname originated from the dense growth of duckweed that covers canal surfaces in vibrant shades of green during the summer.
The marsh system was extensively modified starting in the 11th century by Benedictine monks who dug canals to drain the land for agricultural use.
The park covers parts of three different French departments: Deux-Sèvres, Vendée, and Charente-Maritime.
Traditional boatmen use a 'pigouille', a long wooden pole, to navigate the shallow, narrow canals instead of oars.
The Marais Poitevin is home to the European otter, a species that is highly sensitive to water quality and serves as a bio-indicator for the park's health.
The area features a unique hydrological system where some parts of the marsh are artificially flooded during winter to maintain soil fertility.
The Regional Natural Park of the Marais Poitevin is the second-largest wetland area in France, colloquially known as the Green Venice. It consists of over 100,000 hectares of interconnected canals, reclaimed marshland, and protected meadows. The landscape is split into the wet marsh, known as the 'Venise Verte', and the dry marsh near the coast. Visitors explore the dense network of tree-lined canals primarily by flat-bottomed boat, a traditional vessel known as a 'barque'. The park functions as a critical sanctuary for biodiversity, hosting diverse flora such as ash, alder, and willow, and fauna including otters and numerous migratory bird species. The area has been recognized by UNESCO as a Global Geopark. Coulon, the primary hub, serves as the main administrative center for the park's management. Traditional agriculture remains active, with historic drainage systems shaping the current hydrological landscape.

Book a guided boat tour to navigate the smaller, 'wilder' canals that are inaccessible to self-guided visitors.
Bring insect repellent, as the marshland environment naturally attracts mosquitoes during warmer months.
Rent bicycles to explore the 'dry marsh' sections, which feature well-marked cycling paths away from the water.
Relying solely on GPS for navigation within the canal network, as many narrow waterways are not correctly mapped.
Boat rental services typically operate seasonally from spring through mid-autumn; most services pause during winter months.
Stay on marked paths when walking, avoid disturbing wildlife, and keep noise levels low to protect the tranquil ecosystem.
