Combe noire Waterfall

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!

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...

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 !

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!

Once mowed and grazed, these natural meadows have slowly evolved into forest since all pastoral activity was abandoned. Shrubs and spruces have gradually colonized these old meadows. This encroachment of open habitats is threatening for certain species such as Golden Oats, appreciated by herds, or Alpine automn Colchic.
Since 2014, the Nature Reserve has carried out brush clearing and later season mowing in order to restore this environment for autumn grazing.

It's the end of summer... It's during this season that the Alpine autumn Crocus flowers. Its name refers to Colchis in Greece, the homeland to the enchantress Medea.

This plant contains a very toxic alkaloid: colchicine. According to alchemists, this substance, used in very low doses, would cure rheumatism and acute flares of gout.

Take a break on this bridge and enjoy the cool spray from the Combe Noire waterfall. Can you imagine that the glacier of Tré-la-Tête reached this exact location in 1870! Since then, it has lost a few hundred meters but you can still feel its presence through the torrential river which formed impressive sculptures called "giant's pots" by a deafening eroding process of the rock !
