A high-altitude lake, very quiet and rarely visited. The lake is at an altitude of 2,115 m. It offers breathtaking 360° views.

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.

At the heart of the Oisans massif is Lake Brouffier, a high-altitude jewel in Isère. Its shimmering waters reflect the surrounding peaks.

The Col de la Morte from Sechilienne is 15.3 km long with a total drop of 1003 m. The average gradient is 6.56% with maximum gradients of 9.3%. A very nice climb to do during the summer months because the climb is mostly in the shade. When you get to the top you can go down the other side to La Mure.

Hike from the "waterfall", climb in the forest then following the return path of the via ferrata. Attention passages require to put the hands, cables.
