Infos & Booking


The Collector is certainly the most aesthetic part of the Dent de Crolles network.
Approximately 1.5 km long, the Collector alone offers a timeless 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 shafts is necessary to reach this mineral jewel and its basins of limpid water.
The realization of the 4 kms of course requires a very good physical condition. Indeed, it is also a sporting challenge that this outing offers: 10 to 12 hours of underground progression.
A rare, demanding and sublime underground expedition !
