The banks of the largest estuary in western Europe unfold against magnificent landscapes in which cliffs studded with grottoes alternate with lagoons that provide shelter for birds. The chapel dug out of the rock of Mortagne, the Gallo-Roman site of Fâ or the church of Talmont-sur-Gironde are among the jewels of this region, dominated by water, wine and caviar! The Gironde is the only estuary in western Europe where sturgeon breed.
