Back hike

Lake of Plan d'Amont and Refuge of Fond d'Aussois

LAC DE PLAN D'AMONT - ©SavoieMontBlanc-Lansard

This family hike, in the heart of the Vanoise National Park, is an ideal start to your stay. It goes along the lake of Plan d'Amont lined with rhododendrons, and leads you to the plateau of Fond d'Aussois, where the refuge welcomes you.


Did you know that the water level you are walking along and its twin below have a curious function?

These hydroelectric dams are used to power an aerospace wind tunnel where model planes and rockets are tested.

But you don't need such devices to admire these turquoise waters where the Dent Parrachée is reflected.

Let's go on the path lined with rhododendrons and sweet-smelling cembros pines! Many animals live in this small paradise: marmots, squirrels, bearded vultures, ibexes... you will surely cross one of them.

You will arrive on a plain where a peaceful stream meanders. Follow it to the pretty Notre-Dame-des-Anges chapel where a few fluttering jackdaws seem to stand guard.

You will finally arrive at the refuge, overlooking the old "chalet de la Marie". Tym's warm welcome and the organic and local restaurant will certainly incite you to make a stop.

The most courageous are invited to continue on a slightly steeper slope towards the Aussois pass. But your efforts will be largely rewarded by the breathtaking view on the Vanoise and all the surrounding mountains.
