The Camargue is a natural region located south of Arles, France, between the Mediterranean Sea and the two arms of the Rhône River delta.
The eastern arm is called the Grand Rhône; the western one is the Petit Rhône.
Camargue was designated a Ramsar site as a "Wetland of International Importance" on 1 December 1986.
With an area of over 930 km2 (360 sq mi), the Camargue is western Europe's largest river delta. It is a vast plain comprising large brine lagoons or étangs, cut off from the sea by sandbars and encircled by reed-covered marshes. These are in turn surrounded by a large cultivated area.
Approximately a third of the Camargue is either lakes or marshland. The central area around the shoreline of the Étang de Vaccarès has been protected as a regional park since 1927, in recognition of its great importance as a haven for wild birds. In 2008, it was incorporated into the larger Parc naturel régional de Camargue.
