This is the most famous and coveted traverse of the Dent de Crolles! A magnificent underground route and a spectacular final exit above the valley!
Imagine crossing the entire width of the mountain, from west to east! That’s what the Glaz-Annette traverse is all about. Pitches, meanders and large galleries make up the 2.3km of a varied route steeped in history. The end of the crossing itself is a moment of intense emotion: immersed in the mountain for around 7 hours, you’ll have earned that breathtaking view of Grenoble and the valley, at an altitude of 1700 metres. A sporting challenge for some, an extraordinary adventure for others, one thing is certain: once you’ve made the crossing, you’ll never look at the Dent in the same way again.
