Chartreuse Mountains

The Chartreuse Mountains form a range between Grenoble and Lac du Bourget, characterized by limestone formations with peaks rising to 2,082 meters. The ridges display steep limestone cliffs and deep valleys shaped by erosion of the sedimentary rock.

These mountains formed through limestone deposition over millions of years, shaped by their sedimentary geology. A major landslide at Mont Granier in 1248 dramatically altered the western section and left visible scars across the terrain.

The Grande Chartreuse monastery shapes life in these mountains through its centuries-old liqueur production, with green and yellow varieties that reflect the region's identity. The monks maintain their craft traditions visibly through the monastery and related facilities scattered across the landscape.

The mountains offer year-round marked trails connecting various summits, with main access points near Grenoble and Chambéry. Visitors should prepare for changeable weather and bring proper equipment for mountain conditions.

Beneath the limestone cliffs lies one of Europe's longest cave systems, the Dent de Crolles network, extending 60 kilometers through the rock. This underground labyrinth contains subterranean lakes, rivers, and canyons that continue to captivate geologists and cavers.
