Lake and river: The Durance River
More than a mere river, the Durance is a force of nature. From its source in Mongenèvre at an altitude of 2300 metres it rolls its way over 302 kilometres until it finally flows into the Rhône. Over time, there has been greater control by man over the river, particularly with the construction of the Serre-Ponçon dam, and it is an essential artery for the Hautes-Alpes.

[Trek] Tour de la Baume by mountain bike
Starting from the Sisteron Tourist Office, follow the Chemins du Soleil route through the town and past the lake. The route crosses the Durance Bridge, passes at the foot of the Rocher de la Baume, and follows Napoleon’s historic road (offering a beautiful view of the town and the valley). A climb up a dirt track leads to Entrepierres. After the village, turn left toward Old Entrepierres and continue on a single-track trail called “Le Détroit” (you can stay on the small road if you prefer, which is easier). Ride on to the Col de Mézien (814 m). Finish on the north-facing slope of La Baume with a lovely trail that leads back to Sisteron, mostly along the Way of St. James (be careful on the descent; hikers use this route).Modified: 1 week ago
