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.
This lake is a treat and depending on the humidity and light you will experience different shades of turquoise blue. The ideal place to swim and cool off in summer.
