Very beautiful view when the sky is clear, remember to take a windbreaker at the summit, you will find ibexes. The area is really very simple and does not require strong hiking / trail experience (for the altitude 2930 I think)

In winter as in summer it is perfect, full of spots for bivouacking, a walk or a trail, there are no dangerous areas, and all the passages are simple and well indicated! 👌

Magnificent lake! Accessible to all! As a bonus, you'll find ibexes and a few marmots if you're lucky. For the more courageous, you can climb to an altitude of 2,900 m by continuing on the path with a magnificent view if the sky is clear!

The Robert Lakes are very beautiful, and the mountain range surrounding them creates a magnificent setting. The spot seems popular with campers (arrive early for the best spot). The GR trail between Chamrousse Le Recoin and the Robert Lakes, which passes by Lac des Prouettes, is quite difficult (steep) on the Robert Lakes side. The trail higher up the mountain is easier (beware of the scree slopes for those with short legs).
