In the arid and incultivable hills, people have long maintained a strong agro-pastoral activity. Raoul DECUGIS, local scholar and former president of the association Les chemins du patrimoine, proposes a hike in these hills to discover the small rural heritage. Shepherds, apiés, lime kilns will be part of the party. The start is at 9h at the bottom of the parking lot of Châteauvallon. Provide good shoes and water.
