After a gentle downhill start of almost 5 km, it's not until you reach the outskirts of Pierrelongue that the first climb awaits you. You'll pass through this village under the perched silhouette of the Notre-Dame-de-Consolation chapel (19th century), built on a rocky spur. A few pedal strokes further on and you'll pass the village of Mollans sur Ouvèze on your left to take the small road leading to the Ayguemarse valley. Here, too, you'll follow a small road up the valley to Propiac, a village once famous for its spa. You'll then end your tour in Beauvoisin, with its marl landscape, before returning to Buis les Baronnies.
