After a beautiful gravel climb, you reach this plateau with stunning views (including the Picos de Europa in the distance). The path then continues for a long time at altitude, with many cows and horses. Take a look: https://www.youtube.com/watch?v=OgEcgF17RDw

Indeed, a beautiful spot with breathtaking views, both towards the Picos de Europa and other Cantabrian mountains. The (gravel) road there is also stunning; just take a look: https://www.youtube.com/watch?v=OgEcgF17RDw

A hill located below the summit of the same name as the Saja reserve, resting on a ridge of gentle elevations above the Cabuérniga valley. These Saja mountains are often known as the Sierra de Bárcena Mayor, due to the town that lies at its feet at an altitude of 534 metres. In ancient times, the so-called Camino de Castilla or Reinosa road crossed this ridge towards the lands of Campoo. From Los Tojos (636 m) and Colsa (729 m) the ridge was reached at the Venta Vieja hill (1152 m), where one of the many inns that awaited the traveller along the way was located.
