The environment is exceptional, forests, streams, stone houses with slate roofs ... Haut-Couserans is a reserve of pure air and greenery, it is very exotic. Hiking, hydrotherapy and pastoralism particularly characterize this sector.

Our advice

When the snow melts, the waterfall is filled with water 💦. That's when she is the most impressive. The ideal is therefore to hike to the Cascade d'Ars at the end of spring, in May or June.

To walk to the top of the waterfall it takes 2 hours, for the round trip it takes 3:30 to 4 hours.

The path offers magnificent views of the village of Aulus-les-Bains, of the mountain, streams, forests, the various views of the waterfall… a delight!

In summer, the sea spray cascade are a real treat after 2 hours of walking!
