A 2 day hike in high-altitude mineral landscapes with a view of the Vanoise glaciers and the high-altitude grasslands.
The Petit Mont Blanc was called the “Salt Mountain” by the old Pralognanais. Its salt, actually gypsum, was used for the manufacture of plaster to seal the dry stone walls. To upstage Chamonix, the capital of mountaineering, Pralognan-la-Vanoise, the capital of hiking renamed its Salt Mountain to Petit Mont-Blanc. Incidentally, the view of Europe from the summit of this mountain is stunning. The surreal lunar atmosphere at the summit of the Petit Mont-Blanc offers a 360° view of the Vanoise glaciers, Mont Blanc, the Gébroulaz glacier or the valley of the Avals valley. Clarisse Pellet, Vanoise National Park Ranger.

    Summer mountain pasture cheese dairy

    Agriculture is still anchored in the mountain way of life in Pralognan, as you can see in the daily production of AOP (protected designation of origin) "Beaufort Chalet d’Alpage" cheese, which is regarded one of the best in the Alps! Find out how it is traditionally made.
    Local produce on sale at the Fromagerie du Plan, in Pralognan village centre.
  • Know-how

    Les Prioux

    "Stop at the hamlet of Les Prioux, to witness (depending on the time) the making of Beaufort at Rolland. This cow’s cheese, cooked, pressed and smear-ripened (salted and rubbed) has been labelled PDO (formerly CDO) since 1968. It is known as the “prince of gruyères”. Only the tarentaise and abondance breed can claim to give their milk. The appellation ""Beaufort d´Alpage"" is attributed only to cheeses made in summer, with the milk of a single herd, as is the case with your hosts."

    Les Prioux hamlet

    At the edge of Vanoise National Park, Chavière Valley unveils its natural wonders along a refreshingly varied path: the Savoyard discovery tour around Les Prioux.

    Life in this hamlet, perched at an altitude of 1,700m, is still very much in step with nature and the winter and summer seasons, and residents have had to adapt accordingly.

    This refreshingly varied path unveils the wonders of Chavière Valley to you, with its awe-inspiring peaks and more relaxing hamlets.

    The route is accessible to everyone, including families with pushchairs, the elderly and wheelchair users with helpers.

  • Flora

    The Ecological Land Reserve of Petit Mont-Blanc

    The Ecological Land Reserve of Petit Mont-Blanc was established in 1999 because of the site’s high heritage value. It is managed by the National Forestry Commission which is responsible for maintaining the richness of this area over the long-term. Indeed, there are remarkable habitats to be found here with a substantial floristic diversity (319 listed plant species, of which 11 are protected at national level) A Natura 2000 area, the “Vanoise Massif” stands supreme over this reserve. This area is comprised of arctic-alpine riverside grasslands hosting specular blue thistles and giant scabiosa.
  • Geology

    Col du Mône

    The Col du Mône is located on a fault line that separates two different geological formations: the Mône rock which is a formation of limestones and dolomitic stones from the Jurassic whose stratigraphic series is reversed, and the Petit Mont-Blanc which is formed of gypsum, a very white rock. On the Mône rock, the rocks are rather grey, formed in layers with a reddish layer of bauxite, a rock rich in aluminium and iron oxide. The Petit Mont-Blanc looks like a lunar landscape with its white, globe-shaped rocks.
  • History

    The etymology of Courchevel

    "The origin of the name Courchevel comes from the local terroir and agropastoral practices. Thus in the spring, when the herds of tarentaise cows were moved at altitude to the montagnettes, between 1,500 and 1,800 metres in altitude, the herdsmen were prohibited from stationing their herds on the strips of land where the green grass grew profusely, as although appetising it was capable of cutting the cows’ tongues, enough to “skin it”. This explains the origin of the town’s name, “écortzevé” in saint-bonnais patois, which over the centuries and oral transmission, became “cortzevé”, then “corchevé” and finally “courchevel”. In the 19th century, the maps mention the place known as ""Les chalets de Corchevel"", today ""Courchevel 1550"". The name Courchevel became permanent at the beginning of the 20th century."

    Alpage des Avals: the secret of an earthworm

    "I am the redworm, the earthworm compost: I digest the whey produced from cheese making by ""vermicomposting"". I need a dark, damp and well-ventilated place to live. This is why the compost here is protected by opaque tarpaulin that allow air to flow through. The farmer regularly sprays it with the whey. In order to move and feed myself, I dig tunnels. This facilitates the circulation of liquid and contributes to the mixing and aeration of the earth. The oxygen available allows the bacteria to break down the organic matter that make up the whey."

    The Alpage des Avals: Beaufort cheese

    "The Alpage des Avals is managed by a pastoral consortium whose cattle herd totals approximately 150 cattle. These cows graze around the villages until June and then climb up into the mountain pastures. Their presence in the municipality lasts 8 months. Saint-Bon-Courchevel is located in the Beaufort protected designation of origin area. In the alpine grazing season, the cheese, made on site, can use the ""Beaufort d´Alpage"" label. Almost all farmers are engaged in a dual activity relating to tourism. In winter, they work as ski instructors, shopkeepers, piste service or ski lift operators."
