Lac Cornu is a mountain lake located between the summit of the Index chairlift and Planpraz. The neighbouring Lacs Noirs are just ten minutes away.
Located about 10 minutes from the Black Lakes. The Lac Cornu is snowed in or iced over almost 9 months of the year! It is a quiet and peaceful place from which you will be able to see most of the time, a beautiful band of wild ibexes, hanging on the walls surrounding this mountain lake.
  • Tips
    Beware, high altitude lakes are fragile! Please respect the area: do not swim or wash your dishes, do not trample the wetlands, do not put water sports equipment (buoys, paddles, etc.) in the water or throw anything into the lake (stones, waste).
