La Buffe

La Buffe is a limestone summit in the Vercors massif, forming the northernmost peak of the western ridge in this region. The terrain is composed entirely of limestone formations that shape the landscape with their distinctive pale rock faces.

This location gained importance through the construction of the Mortier tunnel beneath the summit, a major infrastructure project from the 20th century. The tunnel is now permanently closed due to structural collapses in the limestone formations.

The peak forms an integral part of the Vercors Regional Natural Park, marking the northern boundary of the characteristic limestone formations.

The ascent follows marked trails that connect with the European long-distance path E4, offering various route options for visitors. Bring sturdy footwear and prepare for changeable mountain conditions at altitude.

From the summit, a broad panorama opens across the surrounding regions with views reaching toward different landscapes and valleys. This wide-ranging perspective makes it a special location for those seeking to grasp the full scope of the Vercors massif.
