Following the path along the mountain wall, you will be able to appreciate the waters of the Borosa River that descend on its rocky bed.

A few meters away there is a wooden bridge that will continue to connect the route and further on, take a detour to the right to reach the Cerrada de Elías. This change of direction takes you along a narrow path called Vado Rosales, which is surrounded by a lot of vegetation and once you reach the gorge or the Cerrada de Elías, you can appreciate the greatest beauty of the Borosa river route, because thanks to the wooden walkway delimited on the rocks, you can walk on its crystal clear waters and, therefore, have a better view.

When you arrive at the Salto de los Órganos power plant you will be able to appreciate a waterfall with a height of 60 meters that is worth it.

And if you still have the strength to keep going, you will have to ascend vertiginously along a path to the left of the waterfall, in order to arrive at the Aguas Negras Lagoon, not before going through tunnels to finally reach the source of the Borosa River and, why not, continue another 1 km to the Valdeazores lagoon.
