Valleys, plateau, mountain pastures

The plateau Matheysin peaks at more than 900m high. It is spread from the lakes of Laffrey, to La Mure and is bordered by massifs of Tabor and Grand Serre in the East, by the Sénépi and Conest in the West and the gorges of the Drac in the South, which divides it from Trièves.

There are 4 glacial lakes (Lake Mort, Laffrey, Petichet and Pierre-Châtel), great spot of nautical and water activities. The plateau offers an amazing panorama over the Obiou, that overlooks the territory.

The plateau matheysin is historically marked by the intense and diversified mining processing. The headframes of Susville, La Motte d’Aveillans et de Prunières show the mining operation which brought prosperity to the territory, during decades.

Matheysine is the 2nd pastoral territory in Isère. From Sénépi and Conest, to Grand Serre and the valley of La Roizonne, it is around 26000 beasts (cows and sheep) living each year in the Matheysine alpine pasture.

The mountain pasture of Sénépi is the biggest bovine one in Europe. There are 900 heifers living on this 1200 hectares area, protected by one shepherd, Sylvain TURC.

Composed of 3 summits, la Peyrouse, 3 Têtes and Beauregard, the 3 summits of Conest, quite easy to reach, with an exceptional belvedere on the plateau Matheysin  welcome beasts to graze.

Main of the sheep pasture are on Grand Serre and in the valley of La Roizonne. In this valley, you will also find cows and sheep.

In the East of La Matheysine, the valleys of Valbonnais are a large part of the national park of Les Ecrins.

Entraigues is a crossroads of the valley of La Malsanne joining Oisans and of the high valley of La Bonne, extremely wild, entering the heart of the national park of Les Ecrins, until Olan (3564m high). At the summit of the valley of la Malsanne, Col d’Ornon is a family winter (alpine skiing, cross country skiing, snowshoeing) and summer (hikes, mountain bikes) resort.

Below, at the crossroads of these valleys, there is Valbonnais and its lake, ideal for relaxing and leisure time.

The last valley is the valley of La Roizonne, very rustic, going up to the resort l’Alpe du Grand Serre, an other winter and summer resort.
