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).

A small mountain lake at 1810 meters above sea level that often goes unnoticed due to its proximity to Roberts Lakes. Keep your eyes peeled for an alpine newt, and cut some pourettes (chives) for your evening meal.

An easy pass, away from traffic, in the very heart of the Alpe du Grand Serre Station. From Séchilienne, approx. 15km for D+ 1000m. To do in summer to enjoy the freshness of this shady slope.
