About the crag
Climbing at Le Der: discover the complete topo for this crag, with all the routes, their grades, access and practical info to climb at the site.
A small cliff about fifteen meters high. The right and left sections consist of solid gray rock. In the center, the routes require more caution due to more fractured rock. Historically, 13 routes were established by the RSCM in 1960, to which 6 new routes opened by P. Bocia have been added. Access to the cliff is via the Biscutelle trail to the summit of Seconde Jeunesse, then up above it and across the hillside along a small path marked with red dots. Allow 15 minutes from the parking lot. The re-equipping was made possible thanks to a donation from the Grimp’Eure club (St. André de l’Eure), which provided the adhesive, the national FFME for the carabiners and belay rings, the FFME 27 Regional Committee for the tension rod stems, and the Conservatoire de Normandie—owner of the cliff—which provided us with wire fencing and made its staff available for 3 hours to clear brush from the trail. Add to that more than 88 hours of drilling, gluing, cleaning, and marking… all done by route setters and volunteers!
