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 bike
The route starts in an urban area, leaving Sisteron and following the Durance River southward.
After crossing the Durance (near the wastewater treatment plant), the route climbs toward the village of Entrepierres via the D217. Pass through the small village until you reach the base of a rocky cliff. You’ll go around Montagne de la Baume. You then follow the GRP trail of the Grande Traversée des Préalpes to the Col de Mézien (814 m). From there, you can begin a beautiful descent on the D3. This road offers a panoramic view of the Durance Valley and then of Sisteron and its citadel from the heights. The return to town is via the bridge over the Durance.Modified: 3 weeks ago
