Le Grau-du-Roi is a
commune in the
Gard department in southern
France. It is the only commune in Gard to have a frontage on the
Mediterranean. To the west is the
Herault department and
La Grande-Motte village, and to the east is the
Bouches-du-Rhone department. Using the sea as a vantage point, the commune has four distinct sections: the right beach (Plage de Rive Droite), the Village, the left beach (Plage de Rive Gauche), Port Camargue and L'Espiguette. Immediately landwards are the large shallow
étangs, saline marshes, which separate it from
Aigues Mortes, a neighboring mediaeval walled city that used to be a port. The
étangs are home to numerous
flamingoes.
