Discover the northern plateau of the Glandasse mountain, an unforgettable getaway in the Hauts-Plateaux du Vercors Nature Reserve.
This hike begins by progressing in the large pine forests before reaching the Hauts-Plateaux du Vercors and its wide open spaces. From up there, the landscapes are even more grandiose.

6 points of interest

  • Shelter of the Pison

    A short distance from the Hauts-plateaux at 1540 m, the shelter of the Pison is a shack in sheet metal, able to accomodate 6 people. It has a stove.
  • Col du Pison

    The Col de Pison gives access to the Glandasse mountain, which overlooks the Diois from its 2041 m high. Its cliffs are appreciated for climbing, while its summit plateau is a place of estive for many sheep. Included in the nature reserve of the Hauts Plateaux of the Vercors, the fauna and flora are rich.
  • The Nature reserve of the Hauts-Plateaux of Vercors

    Unique by its size of 17,000 hectares, the Réserve des Hauts-Plateaux extends over 10% of the territory of the Regional Natural Park of Vercors. Today it is the largest terrestrial reserve in metropolitan France. Between 1050 m and 2341 m of altitude (with the Grand Veymont in climax), it undergoes very contrasted climatic influences, at the hinge between the northern and southern pre-Alps. The strong seasonal human presence has shaped it since prehistoric times. Pastoralism has been practiced there for over a thousand years.Now marked by an alternation of mountain pastures and forests, the Reserve has the largest forest of hooked pines in the limestone Alps and a rich flora of 738 species. Animal life is discreet but abundant.
  • The Vulture Ball

    At the dawn of the 2000s, the Regional Natural Park of Vercors participated in an operation to reintroduce vultures fawn on the scale of the Pre-Alps. These birds had disappeared from our mountains in the 19th century. By relying on the population of the Grands Causses, the idea was to exchange (birds, and therefore genes) with the Pyrenean populations. A vast population occupies a space that goes from the Spanish Pyrenees to the Vercors, which the birds traverse freely (the observation of the banded birds proves it to us). The Col de Rousset and the circus of Archiane are two sites of rest and nesting for these great gliders (almost 3m of wingspan). They use the ascending currents along the cliffs to transit from one to the other. A large shadow on the ground, raise your head, a vulture passes over you ...
  • At the crossroads of several important trails, the Cabin de Pre Peyret is one of the most frequented of the massif. Located at the entrance of the high plateaus at 1600 m, this unguarded stone hut can accommodate 10 people for the night. It has a stove.The place exudes an old tradition of welcome because it is an old cabaret where those who were penniless went to drink at the Fountain of the Endettés, which bears his name well.
  • The Pas de Chabrinel

    The Pas de Chabrinel is one of the gateways to the Plateau du Vercors. During the descent stands facing you the Dent de Die, as laid down on the side of Mountain. From the height of 1610 m, it dominates the Diois.
