A space shared between Charente-Maritime and Gironde

The Gironde estuary, 75 kilometers long and 12 kilometers wide at its mouth, is the largest estuary in Western Europe. It covers a total area of 635 km².

Beautiful Villages along the Estuary

The Garonne and Dordogne rivers converge at Bec d’Ambès to form the Gironde estuary. The latter flows past the Médoc vineyards on one side and the Blaye vineyards on the other, both famous vineyards of the Bordeaux region.

On the Charente-Maritime side, one of the most famous villages along the estuary is Talmont-sur-Gironde, with its Sainte-Radegonde church perched on the cliff edge. Among other highly visited villages is Mortagne-sur-Gironde, whose upper town offers a beautiful viewpoint over the estuary.

From the heights of this wild and preserved territory facing the Médoc, you can spot the protective gaze of the Cordouan lighthouse offshore, also known as ‘the lighthouse of kings’ or ‘the Versailles of the sea’. It is currently applying for a place on UNESCO’s World Heritage list.

Discover the Rich Cultural Heritage of the Gironde Estuary

The Gironde estuary is renowned for its cultural heritage. Its banks offer varied landscapes, and fishing brings with it a wealth of still-vibrant traditions.

On its right bank, you’ll discover large cliffs that house the Matata or Régulus troglodyte caves in Meschers-sur-Gironde. Further on, the large hills of this bank contrast with the flatter landscapes of the left bank.

Did you know that the Gironde estuary is used by immense ships transporting the wings, tailfins, and fuselage of the Airbus A380?

“The Canal des 2 Mers by bike,” a renowned cycle route, runs along the estuary before heading towards Sète.
