Sortie Spéléo bivouac : avec le Tour des Grottes;

Explore the sometimes little-known paths of the Dent de Crolles and experience your first forays underground: that’s the programme for this Tour des Grottes. Over 2 days – and without ever leaving the mountain – an original itinerary will reveal 8 of the 11 main entrances to the Dent and allow us to visit 4 of them! An underground bivouac will bridge these 2 days of self-guided discovery. Do you like walking? Are you fascinated by the mysteries of the underground world? Then this Tour des Grottes is sure to meet your expectations.
