Small landing on the Seudre estuary at La Tremblade, in the oyster-farming heart of the Marennes-Oléron basin.

Guide

Approach and anchoring

Entry through the buoyed channel of the Seudre, with strong tidal streams and shifting banks. Passable near high water for most keelboats. Oyster park markers line both sides of the channel, give them a wide berth.

Practical

Limited quayside mooring used mainly by local oyster boats. No visitor facilities on site. Fuel, water and full services at the Port de La Tremblade marina at about 1 km. Shops and market in La Tremblade town centre at around 700 m.

Ashore

Cabanes ostréicoles of La Tremblade and Ronce-les-Bains along the Seudre, with tastings in season. Viaduc de la Seudre, completed in 1972, visible upstream. Sandy beach of Ronce-les-Bains at 3 km by road on the northern side of the estuary.
