Roc du Biolley

Roc du Biolley is a limestone summit in the French Alps standing at approximately 1964 meters. The rocky slopes display layered stone formations and weathered passages that characterize the Alpine landscape.

The summit gained prominence during the 19th century expansion of hiking routes through the French Alps. Its prominent position made it a natural waypoint for travelers navigating the mountainous terrain.

The summit draws mountaineers who value raw Alpine terrain and geological diversity. The peak has become a landmark that locals and visitors use to orient themselves in the mountain region.

The ascent from the Plan de la Lai refuge takes about three hours for the complete round trip. Marked trails guide hikers toward the rocky sections, though sturdy footwear and sure-footedness are essential.

A 100-meter stone tunnel pierces the upper ridge and requires a headlamp to traverse. This underground feature distinguishes the climb from standard Alpine hikes.
