Done over 30 years ago with my father. A magnificent climb that winds through the Lesponne valley, but with a rather arduous section towards the summit at forest level. To be done in spring or autumn depending on the weather to avoid the crowds.

A very beautiful lake at the end of the "walk." A good climb nonetheless, very accessible for someone in good physical condition (me and my Samoyed in easy mode), a little more demanding for people with cardiovascular problems (my father-in-law and his 55 kg Golden Retriever). A very beautiful hike nonetheless, I recommend it to all nature lovers (and ultralight fishermen).

Coming out of the forest, these cabins restored over the years by Georges Buisan are magnificent, facing the peaks.

Lake Ourrec is a small high altitude lake in the Pyrenees located at 1,667 meters above sea level. It is nestled in the intimacy of the Lesponne valley, its banks bordered by meadows offer an idyllic setting for a break.
