The Chartreuse massif is a mountain range in the Pre-Alps, . It culminates at 2,082 meters above sea level in Chamechaude. It consists mainly of limestone arranged in successions of anticlines and synclines forming long lines of ridges. The Guiers river and its tributaries flow in depressions separated by passes, before penetrating the karstic networks dug into the limestone.
The massif is experiencing an economic boom, based on specialized agriculture, modernized forestry, winter ski resorts and tourism for hiking, climbing, visits to cavities and free flight.
The largest towns in the massif are Grenoble (160,000 inhabitants) to the south, and Chambéry (60,000 inhabitants) to the north.
The massif is rich – also – in historical remains and monuments inherited from former occupants since prehistoric times.
