Port de La Grève
The most important oyster port in France, along a 2.5 km long canal connecting central La Tremblade (Place Faure-Marchand) with the Seudre estuary. It is bordered by lively painted huts that are illuminated at night during the season, and at that time festivities with fireworks take place. Traditional fishing boats sail the canal. At the end of the canal there's a viewpoint with views to Marennes and Île d'Oléron, as well as restaurants and souvenir shops.
