The waterfall consists of a first 100-meter drop that forms a pool at its foot, and continues with multiple cascades that come together to form a final drop. Overall, it is therefore divided into three levels, for a drop of 246 meters. It is undeniably one of the most picturesque and imposing in the Pyrenees.

Beautiful waterfall on the GR 10, which requires a slight detour. You can swim in it or just soak your feet.

Fantastic lake, but it's really hidden and not that easy to reach. The distance says little, it has to be a hard journey.

If you want, you can skip the circular route via GR10 and Etang de Guzet and shorten the hike to an out and back route. In July, blueberry bushes line part of the path and they were delicious. ;-)
