The River Vidourle rises is in the Cévennes mountains, northwest of Saint-Hippolyte-du-Fort. Its basin, some 1,335 km², lies entirely within southern France.
It flows generally southeast through the Gard département, Hérault département and then the Gard département again. It is around 85 km long.
For a long time the river did not flow into the Sea but into the marais at Saint-Laurent-d'Aigouze and later, in the nineteenth century, into the étang de Mauguio.
Today, artificial embankments cause it to flow into the Mediterranean Sea between Le Grau-du-Roi and La Grande Motte, discharging on average some 20 cubic meters of water per second into the Gulf of Lyon.
