Infos & Booking


The Collector is certainly the most aesthetic part of the Dent de Crolles network in the Chartreuse massif.

Approximately 1,5 kilometer long, the Collector offers a timeless ultimate journey into the heart of the mountain, where all the rainwater and meltwater has been concentrated for millions of years to give birth to the Guiers Mort.

A long path made up of large galleries and wells is necessary to reach this mineral jewel and its basins of limpid water.

The realization of the 4 kilometers of route requires a very good physical condition. Indeed, it is also a sporting challenge that this outing offers with 10 to 12 hours of underground progression.

A rare, demanding and sublime underground expedition!
