One of the most beautiful waterfalls in the Pyrenees!
The Count of Russell, a renowned Pyrenean climber of the late 19th century, placed her ahead of all her rivals.
246m high in three successive stages, it is obviously at its peak in spring between May and June, when the snow melts.
That said, it is so impressive that each season gives it a particular charm!
The departure is located in the village ofAulus les Bains, 200m above the town center.
The hike to the Ars Waterfall is done in a little less than 4 hours round trip, on a mountain path. Of average difficulty, it is doable with the family, provided you have shoes and have prepared your mountain bag of course: see our hiking tips !

This is one of my favorite walks and I put it on my calendar every year. The path is a bit long, but what a reward when you arrive and discover the place. The waterfall gushes out at the top of the cliff, making an initial jump of 90 m and then drapes the rocks in a green setting. If you are in the area, come see me in Aulus!
