The port of Cordemais is a blatant manifestation of the town's deep attachment to its estuary. Redeveloped in 2008, the site now offers more pitches and an ecological fairing area, a unique structure in the Loire estuary. At the port restaurant, called “O fil de l’Ô”, the chef invites visitors to taste Loire gastronomy
