Lac d'Estaing is a natural body of water quietly installed at 1,163 meters above sea level.
Ornithology enthusiasts can take the time to look for the little grebe. The water bird is indeed often observed on the lake.
Lac du Lavedan sits on a beautiful grassy plateau at an altitude of 2,179 metres. It dominates a series of lakes which are on the heights of the Cirque de Gourette.
