The Sèvre Niortaise flows through Marans, an old commercial port with flower-lined quays. It crosses the Marais Poitevin, also known as the “Green Venice,” with its labyrinth of lush green canals.
The Sèvre Niortaise, a River Worth Visiting
The Sèvre Niortaise originates in the Deux-Sèvres and flows into the Atlantic Ocean, opposite the Île de Ré. The Bay of Aiguillon, traversed by this splendid river, offers varied landscapes that change color throughout the day.
The Sèvre Niortaise, 155 km long, crosses the entire Marais Poitevin. Over the centuries, numerous developments have been carried out to transform this waterway into a commercial route.
The maritime canal from Marans to the sea is a diversion that was dug at the end of the 19th century to serve the port of Marans and connect it to the canal that goes to La Rochelle, then also called the Rompsay canal.
Bird Paradise
The Sèvre Niortaise estuary is today a true haven of peace and tranquility, for birds as well as for tourists. A favorite spot for fishermen, the Sèvre Niortaise is known for its local wildlife. Only a few boats peacefully sail there.
During wonderful strolls, you can admire the green, blue, and yellow colors of these very relaxing landscapes and recharge by visiting the charming small villages that line it. The Bay of Aiguillon is also renowned for its mussel farming, with the famous and succulent Bouchot mussels from Charron. In Esnandes, the Marais Poitevin Bay House welcomes you to learn all about local traditions.
The Sèvre Niortaise gave its name to the Deux-Sèvres department, along with the Sèvre Nantaise. It also separates the Vendée and Charente-Maritime, connected by the famous Brault bridge.
