Infos & Booking


Imagine: Crossing the Dent de Crolles mountain in its width, from west to east! That's what the Glaz-Annette crossing proposes.

Wells, meanders and large galleries make up the 2,3 km of a varied and history-laden route. The end of the crossing alone represents a moment of intense emotion: Immersed in the mountains for about 7 hours, you will have deserved this breathtaking view of Grenoble and the valley, at an altitude of 1700 meters.

Sporty challenge for some, an extraordinary adventure for others, one thing is certain: once this crossing has been completed, you will no longer see the Dent the Crolles the same way.
