  • The nature reserve

    A few steps away from the true entrance to the nature reserve, a panel presenting the issues of this protected and regulated natural space.
  • The roman route

    More than a touristic itinerary, the roman route was one of the main ways of crossing the Alps during Antiquity!
    Before the Roman invasion, Val-Montjoie was home to Ceutrons, a Celtic tribe practicing livestock breeding. For their cheese production, they imported salt from Moutiers via the Col du Bonhomme mountain pass. They participated in the establishment of these routes leading to Italy, which were taken by the Romans during the invasion of the Alps.
    Observe the section of Rochassets, it was carved in the rocks in order to create a passage for the charriots!

  • Flora

    The bogs at la Rosière

    On your left are located the bogs of La Rosière, but be careful, admire them from the trail because these are fragile habitats with high biodiversity!

    Originating from the ice age, this wetland was first a depression eroded by the glacier in which the melting ice stagneted. It’s a paradise for carnivorous plants such as Alpine Butterwort or the Round-leaved Sundew...
  • Flora

    The round-leaf Sundew

    It is a small carnivorous plant that lives in peat bogs, environments offering few nutrients. Don't worry, it feeds only on insects, which it traps and digests thanks to a sticky substance produced by the red hairs covering its leaves.

    It is called "Rossolis or Sundew" because of the scintillation of this substance in the sunlight.

    This species is fragile and protected, please do not touch it !
  • Small patrimony

    The roman bridge

    Also called "Pont de la Téna", this structure dates back to Roman times! It is located on the ancient strategic route which made it than possible to reach the valley of la Tarentaise and Italy directly from Les Contamines.

    This route, which has become the GR5 since, is a popular tourist destination.

    The bridge overlooks the gorges of Bont Nant.

    Admire the natural pools that the torrent has shaped slowly but surely!

With the development of the long-distance hiking trail "Tour du Mont Blanc", it has become a refuge. But since its creation it has always belonged to the same family! It is open from June to the end of September.

  • The mountain pasture

    Mountain pastures are landscapes shaped by human activities since prehistory, during the neolithic era, when first started livestock farming.
    Without the grazing of domestic animals at this altitude, this environment would be composed by few species of bushes and according animal species. The alpine pasture is a rare example of human activity generating biodiversity in both animal and plant species, more abundant than what the natural evolution of the environment would produce. It hosts many species of plants, birds, invertebrates, mammals...
  • Cow mountain

    How to recognize the breeds of mountain cows grazing together in these pastures?

    The breed called "Abondance" was born in the village of the same name in the Chablais area in Haute-Savoie. It can be recognized by its mahogany-colored coat and belly and its white head.

    The "d'Herens" breed is coming from the Valais region in Switzerland. More stocky, it has a plain coat, often black, sometimes dark red or chestnut. Its lively and belligerent behavior is used during the traditional "Fight of the queens" in the 3 areas around Mont-Blanc. But don’t panic, these games are harmless for the competing animals!
  • Refuge

    The mountain refuge of la Balme

    Located at the foot of ‘Aiguilles de la Pennaz’ (2668 m) on the ‘Tour du Mont-Blanc’ trail, this refuge has been managed by 3 generations of the same family to welcome hikers. This old farm is surrounded by mountain pastures, still managed by mountain farmers.

    Estimate the height of the roof and imagine that during the winter only the chimney isn’t covered by the snowpack!

    This refuge is open from June to September.
  • Fauna

    The Northern Wheatear

    Have you seen Zorro with his black blindfold?!

    This is the male of the Northern Wheatear, a sparrow-sized passerine bird. Nevertheless, this 25g featherweight is a long-distance migratory bird. Indeed, if it comes to nest in the mountains during the summer season, in search of insects such as flies, crickets and other grasshoppers, which abound in the alpine grasslands, it spends the winter much further south, in the savannas of tropical Africa, from Mauritania to Tanzania!
  • Panorama

    Panorama on the Mont-Blanc massif
