Caving
The limestoneplateau is conducive to karst formations. Some pit caves (called 'tannes') are connected to underground networks such as the Garde-Cavale network, accessible from the Trou du Garde and the Creux de la Cavale.[7] More than 50km of this network has been explored. The waters, whose flow varies from 14 to 7,000 litres per second, come out at the Doria cave,[8] which is visible from Chambéry.
In 1965 and 1972, the ski resort of Le Revard was used as a stage finish, with the finishing line being situated at 1,500m (4,921ft). The 1965 stage was a mountain time trial won by Felice Gimondi.[4]
