A small village under reconstruction and repopulated, but with no services, just a social club selling sweets. Very pretty. The place names here don't deceive you: Aldea de Ebro, Plaza Tres Iglesias,...

We set out with the hope of ascending to the summit of Tresmares, where the Hijar-Ebro River begins and flows into the Mediterranean, the Pisuerga River (a tributary of the Duero River) flows into the Atlantic, and the Nansa River flows into the Cantabrian Sea. But a thick, damp fog covering the landscape forced us to give up and head back down the same way we came up. The road is partially covered by a bike lane and very little traffic. A steady climb of around 10%. Absolutely recommended. A few years ago, the Alto Campoo pass was the final stage of La Vuelta a España.

Officially, it's the source of the Ebro River, in Fontibre. However, according to what we were told at the tourist office, the waters of the spring pools come underground from the Hijar River, which rises in Alto Campoo. Specifically, in Tresmares, where the Hijar-Ebro begins, flowing into the Mediterranean; the Pisuerga (a tributary of the Duero) flows into the Atlantic; and the Nansa flows into the Cantabrian Sea.

You can climb from Cieza or Los Llares. The road is dirty and somewhat broken through Cieza (be careful when descending on a road bike).

The San Andrés Bridge is in Somahoz (Los Corrales de Buelna) over the Besaya River, which gives access to the San Andrés neighbourhood. It is divided into a narrow lane for vehicles and a pedestrian crossing, and from it we see a railway bridge that we have to go under to enter the neighbourhood. And that railway bridge (or overpass) that we crossed is part of the historic "Ferro-carril de Isabel II" (Isabel II Railway) that began to be built in the mid-19th century with the project of joining the towns of Alar del Rey with Santander and whose section from Bárcena de Pie de Concha to the Cantabrian capital must have been finished in 1858.

The Sanctuary of Las Caldas del Besaya is a fantastic Baroque monastery dating from the 17th - 18th century and located in the Corrales de Buelna, very close to the rural centre and on high ground, next to the motorway towards the Meseta. Inside, it contains an important group of Baroque altarpieces, highlighting the Main one, with an image of the patron saint, Our Lady of Las Caldas, from the 16th century. The side altarpieces are from the 17th century, in the Churrigueresque and decorative Baroque style. The cloister has a square plan and preserves several canvases from the end of the 18th century, dedicated to the founder of the order, with scenes from his own life.
