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).
