Enjoy a walk along this terraced path, eyes drawn to the hypnotising colours
of the lake. Feel the serenity as you cross the sunny alpine pastures and
clearings. Hike right into the Vanoise National Park. You'll feel like you're
a million miles from home!


If you love views of landscapes dramatically falling away from you, then every
step of this hike will be a delight. The artificial lake, twinkling like a diamond
in its case, attracts your eyes every time you look up towards the horizon.
Whatever the season, the colours cast a magic spell. Even the marmots'
little cries of alarm won't take your attention from the satin-smooth surface.
This water basin in the high-altitude grasslands plays a crucial role in storing
water for the neighbouring valley. Like its downstream counterpart, Plan
d'Amont's hydroelectric dam is used, among other things, to power ONERA's
international wind tunnel, a flagship aerospace research project that tests
model aircraft and rockets.
At La Fournache refuge, take a rest as you imagine all those seasoned
mountaineers heading towards Pointe de Labby or Dent Parraché, majestically
rising up above you to a height of over 3,500 metres above sea level.
