a superb hike to do. Very impressive when the dam is under construction and the lake is almost empty.

A very nice hike to do. Bring good walking shoes and think about leaving early. Your arrival at the refuge will be the best place for a snack break and to regain your strength before starting the return descent.

Located a few steps from the dam of the lake of the same name, the refuge overlooks the valley. Comfortable and bucolic, it welcomes visitors all year round. More information here: https://refugedeloule.fr/.

Very beautiful point of view on the surrounding peaks as well as on the peak of Bastan which awaits you. The night at the edge of the lake is very pleasant.
