Pass road in perfect condition. 7km constant climb from 40 to 340m pass height. The descent is also a dream.

Already pretty much at the end/beginning of the railway line, here it is even asphalted, before/later not anymore, but always easy to ride.

The Torre de los Baranda, in Espinosa de los Monteros, is a stately building that reflects the historical importance of the area's lineages.
