Superb view of snow-capped mountains. Fairly frequented place, to do out of season.

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.

Narrow Passage with Balanced Boulder

Highlight • Natural Monument

On the way up or down, this passage can be scary but is in fact not at all dangerous or exposed. However, it is better not to have too big a bag!

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?
