The Marine Nature Park covers 6,500 km2 of marine area and encompasses all the Pertuis narrows, estuaries, the Gironde plume and extends off shore to a 50-metre water height.

As the largest estuary in Western Europe, the Gironde is subject to very strong tidal currents and small islands appear and disappear at the whim of the river.
It is located just downstream of the centre of Bordeaux.

114 coastal towns are part of the park along 1,000 kilometres of coastline.

The management board is in Marennes.
Other main coastal towns are (from north to south): Saint-Martin-de-Ré, Sainte-Marie-de-Ré, La Rochelle, Rochefort, Saint-Pierre-d'Oléron, Le Château-d'Oléron, La Tremblade, Saint-Palais-sur-Mer, Royan, Soulac-sur-Mer, Pauillac.
