Stand in the citadel of Sisteron and feast your eyes on 150km of awe-inspiring landscapes. Discover the medieval town - the gate to Haute-Provence - with its monuments and picture-postcard bustling streets! Sisteron, which has been awarded the "Most Beautiful Detours of France" label, has a maze of staircases and narrow arched streets known as andrones that lead up to the towering citadel, which Henry IV touted as "the most powerful stronghold in my realm". Take the Route Napoléon to the hilltop villages of Upaix and Ventavon and continue your adventure by exploring the Méouge gorges, one of the wonders of Hautes-Alpes! This Natura 2000 site is hiking and cycling heaven. The temptation to go for a swim in the turquoise-tinted waters of its basins may prove too hard to resist. The next stop is Orpierre, a charming medieval town in a scenic landscape, snuggled up against sheer cliffs that are wildly popular among climbers. Follow the little bucolic roads to Rosans, a village that goes all the way back to the Middle Ages, and the Cluniac priory in Saint-André-de-Rosans. From there, keep on going to Serres and Garde-Colombe, two Petites Cités de Caractère® (Small Towns of Character)!
