Oucanes Chabrières

There is something for everyone!


From Réallon station, take advantage of our panoramic chairlifts to reach the Serre du Mouton crest. A breathtaking panorama on the Serre-Ponçon Fjord, Les Ecrins National Park and the Chabrières Points. Let yourself be tempted by this aerial hike and take on this emblematic mountain of Serre-Ponçon.

This summit, made up of many sharp points, is unique. “Mountain thrills and ambiance, but no real difficulties. You will be amazed during the stiff, but short ascension of the Chabrières Breach, in the middle of the points. Coming later the stange discovery of the unusual Oucanes, a real limestone crevasse maze!!

From the breach, the access to the summit of the Points is possible, but the itinerary is steep and unmarked. Not recommended for children.

The panoramic chairlifts of Réallon allow the soft discovery of the mountain. From the Serre du Mouton crest, several other downhill hikes allow you to reach the station where you can ejoy, relax and restore yourself on sunny terraces.

Les Ecrins National Park


Created in 1973 after being prefigured in 1913 at the instigation of mountaineers, some naturalist associations and the French Alpine Club, Les Ecrins National Park is one of the ten French National Parks. It is a high mountain territory which culmunates at 4102 meters above sea level, at the Barre des Ecrins and delimits the geographical and climatic border between the Northen and Southern Alps.

Serre-Ponçon is the southernmost of the Park’s sectors. Here, the peaks flirt with the 3000 meters altitude and have their feet in water. The hiker can therefore go from the Mediterranean influence of the Nival level and meet a very diverse fauna and flora.
