Chalet Hôtel du Gioberney, a paved road in the heart of the Écrins Park
Chalet Hôtel du Gioberney is a high mountain refuge at an elevation of 1.649m (5,410ft) above the sea level, located in the Isère department in southeastern France, within the Cirque du Vaccivier.
Located in the Alps, in the heart of the Écrins National Park, the road to the refuge is paved but pretty narrow and steep (with some sections up to 10%). It is called D480T. The road is usually impassable in winters. Risk of rock slides.
The refuge was built in 1942 by the Vichy government. It is the starting point for many hikes. The last petrol station is at the entrance to the valley. Remember to fill up with gas because the refuge is circa 30 km away. Starting from N85, near Saint-Jacques-en-Valgodemard, the road is 26.2 km long. Over this distance the elevation gain is 784 meters. The average gradient is 2.99%.
