The plateau of Sornin

The plateau of Sornin  is part of a Sensitive Natural Area (ENS) "La Molière-Sornin". It is a prairie of estive subject to the problematic of the development of spruces that close the environment. As a result, a policy to restore the Sornin meadow has been put in place to keep this environment open and to preserve the biodiversity of the site as well as possible.

The Black Grouse

The black grouse takes its name from the superb tail in the form of a lyre which is provided by the male. It frequents the edge between the upper limit of the forest and the alpine lawns. It is a fierce and very discreet bird for much of the year. It remains hidden in the vegetation cover, moving by walking in search of small invertebrates, berries or seeds. In winter, this varied diet leaves room for coniferous needles and buds. It is in spring, with the nuptial dancing of the male, that these birds are more visible and noisy.

The Gouffre Berger

Beneath your feet is one of the largest subterranean networks of the Vercors, that of the Gouffre Berger. His discovery in 1953 by J. Berger led to a formidable human adventure which led in 1956 to the crossing of the coast -1000 meters, the first of the world speleology. The adventure is not over because the connection with the Cuves of Sassenage is always actively sought!

The shepherd's hut

Herds have been kept on the Sornin for a long time. The communal shepherds already kept oxen and bulls, and from 1935 to 1985, 6,000 sheep grazed in the summer. Today, the 1,800 sheep that still make up the herd liven up this mountain pasture where the panorama is truly exceptional. It was in 2004 that the first wolf attack took place in the Sornin, and since the mountain dogs stand guard.

Recommandations

Be careful on the edge of cliffs!

You are going to go through the summer pastures, maybe you will meet protective dogs, often Patou. Always be sure to bypass the herds, while remaining calm while the dog identifies you, not caressing or threatening them. If you have a dog (not recommended), keep it on a leash.

Use the passageways to cross the fences, close the gates and barriers, stay on the marked paths.

Staying on marked paths also means respecting private property.
