There are many routes, both easy and difficult, to choose from. The Sierra is very beautiful, especially in autumn.

The path leaves El Portillo on the east side, goes up a few meters along a channel and enters the north side. If the mountain has snow, this section is dangerous because the cold and shady conditions keep the path icy and the fall is fatal; crampons and ice axes would be essential. The alternative is to climb directly along the channel on the east face, with less slope, sunnier and direct to the summit of San Millán (2,131 m), also called El Torruco. At the top there is a small circular stone tower adorned with a metal house and other festival motifs left by mountaineers. The southern slope of the mountain is a large mass of gentle slopes with no remains of glacial activity towards the valley of the Arlanzón River. The descent continues along the west face, enjoying extraordinary views of the Urbión River valley and the glacial cirque where the San Millán lagoon appears half frozen.

The Zarcia Recreational Zone is 2.8 kilometers from Santa Cruz del Valle Urbión along a dirt track suitable for cars, there are some potholes but with care they do not present problems. At the entrance to the picnic areas there is room for three or four cars and 150 meters before arriving there is space for many more. The route begins along the main path of the Urbión River valley, passes through a detour and after one kilometer the Altuzarra waterfalls path appears on the right, which is the return route. The path does not present orientation complications, it follows the course of the water to the head of the valley. In several sections you have to cross the riverbed or walk along the small islands that the torrent forms when there is a lot of flow, always among beech trees, holly trees, yew trees and the riverside scrub that seeks the humidity and wild environment of the glacial valley. Some reference points are the Refugio de Laguarra cabin and shortly after the crossroads where the Mirador de Domingo Sevilla trail leaves on the right, which is also a shortcut to get directly to the Altuzarra waterfalls without passing through the summit of the mountain. . On the opposite bank of the ravine is the “most famous beech tree in Burgos”, as indicated by a sign stuck on a stone near the monumental tree.
