A beautiful waterfall near the Saldropo Wetland. It's wonderful to see it with water.

Beautiful, magical place. The final stretch is difficult to access. Not suitable for everyone. Very steep slope and lots of loose stones. The ground is also quite rocky, so on rainy or humid days it has to be very slippery. Otherwise, it is beautiful and you can take it easy and enjoy it.

Going with days of rain falling the previous days is more beautiful.

By slowing the waters of the Cadagua River, these structures create an incredible sound of falling water. An incredible river landscape for hiking.

The Arbina dam backs up the river bed of the Butrón River. Here the environment is full of oak groves, lime trees and, in some areas, alder, ash and acacia trees.
