Below a limestone cliff of several hundred meters, is the village of Fontaine-de-Vaucluse which owes its name to the source of Sorgue. Kart spring, the largest in metropolitan France and the fifth largest in the world, comes from an underground basin of 1,100 km2, recovering the waters of Mount Ventoux (visible in the distance), the Vaucluse mountains, the Albion plateau and the mountain of Lure. La Sorgue, strongly protected, joined the Ouvèze then the Rhône after several subdivisions.
