Meters before reaching the Port or Portillo de la Sía, at 1,200 m. altitude, we find the Mirador, from where we have impressive views of the Soba Valley.

This is one of the best-known climbs in the province of Burgos, not only because it's always the star stage of the Vuelta a Burgos but also because it has appeared in key stages of the Vuelta a España, one of the three most important stage races in the world. A brutal eight-and-a-half-kilometer climb at an average gradient of over 9%.

In the north of Las Merindades, bordering the Cantabrian community, the municipality of Espinosa de los Monteros looms. The municipality is articulated around three small and narrow valleys modeled by the Lunada, Rioseco and La Sía rivers.

El Picón Blanco is a well-known mountain pass, very popular among road cyclists, although it is gaining popularity among donkey lovers, since it can be reached by a forest track in good condition for those who prefer to avoid asphalt. From here it is usually connected to the port of La Sía, the most popular among the ports of Pas.
