On your bike ride between La Tranche-sur-Mer and L'Aiguillon-La-Presqu'île, the La Belle-Henriette lagoon is a unique place, separated from the sea by a narrow strip of sand. Then, La Faute-sur-Mer, which stretches towards the Pointe d'Arçay, will delight you. Next, head to Saint-Michel-en-l'Herm via the Marais desséché (dry marsh). Between Vendée and Charente-Maritime, this stage of the Vélodyssée cycle route takes you to the so-called "dried" section of the Marais Poitevin.
Cycle through vast expanses of marshland and farmland dotted with farms and cabins until you reach Marans, a pleasant riverside town bordered by the Sèvre Niortaise River. Be curious and explore the marina, the historic center, and the church with its futuristic bell tower, all of this town that lives to the rhythm of the water.
