You have to go take a look before or after visiting the Choranche cave. It's not far at all and the trail is accessible even to children. The cave is easily visible (staying outside) without specific equipment. You can then go see the waterfall.

La Glacière is a 14 m deep cave. It is the result of the dissolution and erosion of limestone by the long work of water. In the 1700s, landmarks bear witness to the presence of men who came here to exploit the ice. The latter will engrave various inscriptions on the wall. But it was at the beginning of the 20th century that this cave was mainly exploited. Indeed, the ice extracted using a sled is used by cafeterias in Grenoble and hospitals. In 1964, the cooler was 4 m thick, today it is endangered. The rockslides made access to the cooler dangerous and it was closed to the public in 1999.
