La Grande Sure

La Grande Sure is a mountain peak reaching 1,920 meters (6,299 feet) within the Chartreuse chain of the French Alps, built from limestone rock formations. Its steep slopes and rocky features create a distinctive profile that stands out among the surrounding terrain.

The mountain has been part of the Chartreuse landscape for centuries, serving as a landmark for shepherds and travelers moving through the French Alps. It became an established reference point within the regional geography and the daily movements of mountain communities.

The mountain serves as a familiar landmark for hikers and climbers exploring the Chartreuse region, drawing visitors who come to experience the landscape on foot. Local communities have long used these alpine paths as part of their connection to the surrounding terrain.

Two main routes lead to the summit, one from the eastern side that is easier and one from the western approach that requires more technical skill. The terrain is rocky throughout, so sturdy hiking boots and careful footing are important for the climb.

The mountain contains notable cave systems including the Loup Garou pit and the Jacques Chalon cavern network, offering opportunities to explore underground passages and formations. These karst features reveal the geological structure hidden beneath the surface and attract those interested in cave exploration.
