The Petit-Rhône is one of the two arms of the Rhone Delta that leaves the main riverbed north of Arles to jump into the Mediterranean Sea. The Petit-Rhône estuary is located 2 km west of Saintes-Maries-de-la-Mer and is called Grau d'Orgon. The Clos du Rhône beach, located at the Petit Rhône estuary, is the last beach of Saintes-Maries-de-la-Mer. On the other side of the Petit-Rhône, there is the Espiguette Port Camargue beach.
