A fantastic waterfall, if the Rio Nervión is flowing. If not, the viewpoint is still spectacular.

Unfortunately, the Nervión has no water today, 2.5.25, so the spectacular waterfall was only a viewpoint in the canyon

The Mirador is spectacular but not a drop of water from the waterfall when I went. Of course, I heard the water but I didn't see anything. The cuts are very worth it

Small environment equipped with fences and bridges, to see the fountain and the small karst spring.
