mont Lachat, a successful renaturation project
The sanatoriums of the plateau of Assy
Mountain air and sun being the essential healing ingredients of respiratory diseases, the Plateau d'Assy was chosen at the beginning of the 20th century as the perfect location to build several of these treatment centers. With its exposition to the south, its altitude and its isolated location, their fame was worldwide.

Espace Naturel Sensible (ENS), a protected area
ENS-labelled sites are recognized for their highly-valued environmental features (fauna, flora, landscape) which are threatened or made vulnerable by urbanization or the development of activities.
The Golden Eagle, a true symbol
It is also a source of inspiration for artists, of admiration, even of worship in different civilizations.
However, it has long been persecuted because it was considered to be "harmful". Nowadays, it is protected, like all raptors in France.
The common Kestrel
The Common Kestrel can be found from the seaside to the mountains as long as its prey (small rodents, batrachians and other insects) is present in sufficient amounts.
The behaviour of chamois
When disturbance occurs, it adopts the same escape strategy as when faced with predators (wolf, lynx, eagle for the juveniles): it flees at high speed down the slope! This costs a lot of energy, which is needed to survive in low temperatures and with a lack of food during the winter, or during the breeding season. So of you come across a chamois, give it time to move away quietly.
Chamois or Ibex?
Be careful not to confuse it with the female Ibex which has an almost uniform colored coat, even on the head! The long ridged and backwards curved horns of the male Ibex make it easy to distinguish it from the chamois’ silhouette.
- On the plateau of Bellevue, pass behind the restaurant La Chalette and continue on the dirt road on the right leading steeply up to the ridge of Mont Lachat, then up to the summit, near the orientation table.
- To go back down take to the right of the orientation table and to join the path along the rails.
- At the intersection, take the down going path on the left, not following the railway. Follow this path on the slope of Mont Lachat, until you reach the starting point at Bellevue.
