Combe noire Waterfall
The nature reserve
The roman route
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!
Notre Dame de la Gorge
The bogs at la Rosière
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...
The round-leaf Sundew
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 !
The roman bridge
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!
Hay meadows at la Laya
Since 2014, the Nature Reserve has carried out brush clearing and later season mowing in order to restore this environment for autumn grazing.
The Alpine autumn Crocus
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.
This small diurnal bird of prey, is common but very discreet. It terrorizes passerines, an order including most songbirds, on which it feeds!
It is a predator using a special ‘surprising’ technic to hunt by flying as close as possible to the rock walls or hidden behind obstacles to startle its prey.
