Archiane

Archiane biological reserve spans 727.95 hectares of communal forest in Châtillon-en-Diois, enclosed by towering 400-meter limestone cliffs that form a natural amphitheater at the southern edge of the Vercors massif, dominated by Mount Glandasse.

Established on March 8, 2000, this reserve protects geological formations dating back over 120 million years to the Cretaceous period, with limestone escarpments that have been shaped by millennia of erosion and are listed in the national geological heritage inventory.

The area maintains a thousand-year-old pastoral tradition with transhumance practices that continue to influence the landscape, while local communities preserve ancestral knowledge in sheep farming and traditional cheese-making techniques passed down through generations.

Access to the reserve follows a discovery trail starting from Archiane hamlet, with marked paths allowing natural habitat observation while adhering to regulations that restrict logging, hunting, and motorized vehicles to protect sensitive environments.

The reserve successfully hosts around 80 breeding pairs of Griffon Vultures following their reintroduction in the 1990s, alongside six nationally protected plant species including the rare Lady's Slipper orchid and Wild Tulip.
