At the heart of Île d'Yeu life, Port-Joinville is named after a son of Louis-Philippe, the Prince of Joinville. A lovely view of the port awaits those arriving by boat. In the background are the port's white houses bordering the quayside. Much of the harbour is free of water at low tide. Beyond the quayside, Port-Joinville has an extensive main street and numerous narrow lanes of fishermen's houses.
