western spurs of the Maritime Alps in southeastern France, lying between the Dauphiné Alps (north), the Lower Rhône River (west), and the Mediterranean Sea (south). The coastal massifs of Maures and Estérel are considered part of the range. The mountains are dissected by valleys of the Durance, Var, Argens, and Verdon rivers. The Gorges du Verdon (Grand Canyon of the Verdon) near the town of Castellane is a popular scenic attraction. The hills surrounding the perfume-making town of Grasse are covered with lavender. The area has experienced out-migration and is increasingly dependent on agriculture and tourism.
