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 Casa Palacio that the Ceballos had in Barros is today owned by Mr. Herrero and Mr. Martínez de Azcoitia. It is a beautiful mountain architectural complex with a portal between cylindrical cubes, a typical mansion and a chapel. It was restored a few years ago by the current owners who have managed to give its interior a stately and period atmosphere. It dates back to the beginning of the 18th century.

Giant Barros Stele: Located in the town of Barros, municipality of Los Corrales de Buelna, Cantabria. The Cantabrian Steles found next to the hermitage of the Virgen de la Rueda, in the town of Barros, and the two found in the Lombera neighbourhood, are displayed in a permanent exhibition next to the aforementioned hermitage in what is known as the Parque de las Estelas de Cantabria. These are circular pieces that preserve the base pier, 0.80 metres wide, for vertical placement. The largest one (Barros II), between 2.15 and 2.46 metres in diameter and weighing 3,000 kilos, was found in fragments in 1977 between the walls of the chapel of Nuestra Señora de la Rueda de Barros and was rebuilt in 1999. The Cantabrian stele known as Barros I, also called the Wheel of Santa Catalina or the Wheel of the Virgin, is smaller in size, but its dimensions are still spectacular: 1.75 metres in diameter and 32 centimetres thick. Made of sandstone, easy to work, like the previous one, it has a geometric decoration. Although interpreted by some as religious or funerary testimonies, the steles displayed in the Parque de las Estelas de Cantabria continue to offer researchers numerous questions about their functionality and chronology. There is a possibility that they may belong to the Roman period or even later. They were declared a Site of Cultural Interest in 1985 and since then their image has been part of the coat of arms of Cantabria.
