The Regagnas is the western terminus of the Aurelian Mountain, located in the Var. Its altitude is 815 m at its peak.
This range has an important ecological interest, particularly because of its rocky biotopes where big birds of prey are nesting.
The Pas de la Couelle (531 m), summit on the D12, road between Saint-Zacharie and Trets, is used by many cyclists in the region.
The Regagnas range is reached from Auriol, Belcodène, La Bouilladisse and Saint-Zacharie.
