Orb

Length: 135 km
Source: Mont Bouviala massif de l’Escandorgue
Estuary: Valras mediterannee
Particularity: It is the most energetic Mediterranean river: its flow is supported from the Avène dam to the North East and from the source of La Salvetat sur Agout.

60 km from the Cap d’Agde and 30 km from Béziers, Roquebrun is the Mediterranean gate to the Haut Languedoc natural park. The quiet Orb flows on the foothills of Larzac (Avène), swelling with tributaries from the massif du Caroux  (the park’s natural reservoir) then encircles vineyards and olive groves up to the medieval villages of Vieussan and Roquebrun.
