About the crag
Climbing at Les Rangs de Mars: discover the complete topo for this crag, with all the routes, their grades, access and practical info to climb at the site.
The Les Rangs de Mars crag is located in Pont-de-Barret (Drôme), a climbing site to discover in the area.
The Rangs de Mars site offers two sectors that are highly complementary in terms of difficulty and optimal climbing season. The “Neuf Lune” sector, which is exceptionally overhanging, offers an excellent playground for climbers seeking high difficulty. Unclimbable in winter due to humidity and spring seepage, its north-facing orientation and proximity to the river make it ideal in summer. The “Suzette Flipo and Ricky Banlieue” sector, on the other hand, features a vertical wall ranging from 15 to 20 meters in height, with routes ranging from accessible to moderate in difficulty. Its south-facing orientation makes it appealing during the mid-season and even on sunny winter days. This guidebook was produced in partnership with the CAF Saoû Synclinal, which equips and maintains the area. The print guidebook “Climbing in the Drôme: Drôme Valley & Diois,” managed by the FFCAM 26 departmental committee, covers all the surrounding areas.
