The path enters the beech forest, goes down to the Altuzarra stream and the natural wonders begin. The trail is marked with green and white paint marks on the trunks of the trees, but they are placed to take the route in the opposite direction, they appear after passing the tree that has the sign. On the bank of the torrent there is a path that crosses the riverbed towards the Mirador de Domingo Sevilla, which is the shortcut that we indicated on the way up to San Millán along the Urbión River. The waterfall path goes down the bank of the stream and immediately reaches the upper edge of the first waterfall, known as Salto Alto or Cascada Grande. The balcony is beautiful because of the energy of the waterfall as it falls and the surrounding beech forest. The path goes down some stone ledges to the left of the waterfall. Below the views are impressive, the water jumps over the walls of rocks and mosses creating a beautiful river scene in a suggestive forest environment. The path continues along the bank of the stream and goes down to the base of Salto Medio, another jewel of the Altuzarra stream, and shortly after it passes through Salto Chico, which closes the magnificent trio of waterfalls. The natural steps of the ravine where the waterfalls are formed are quite steep and it is easy to slip on the leaf litter, the floating roots of the beech trees and the sludge caused by humidity, adding intimacy and mystery to the spell of the forest. The path passes through a couple of narrow bends in the stream that require you to jump over the channel several times and exits on the left of the ravine towards a repopulated pine forest.
