Trou du Glaz

Highlight • Other

The Trou du Glaz is a unique place where fallen rocks seem to be suspended in the air. The entrance to the caves is worth a brief exploration and perhaps a brief respite from the sun on a hot day?

At the top of the Dent de Crolles (2,062 meters), the view emerges over the entire Grésivaudan valley. Second highest summit of the Chartreuse massif after Chamechaude at 2082 meters, its ascent is however more technical.

Too bad about the view! But we came across chamois, marmots and a flock of 1000 sheep, patous and a very friendly shepherdess who explained her activity and the problems with the wolves. Despite this lack of sun, the day was very pleasant as always in the mountains.

Technical hike to be avoided for children if they are not sporty and for adults with little or no mountain experience. Some passages with cables and air. Venture there while being well equipped...
