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.

On a hill, and guarding the road that linked the coast with Castilla through the Saja Valley, is the Castillo de San Vicente, in Argüeso, within the municipality of the Brotherhood of Campoo de Suso, in the South from Cantabria (Spain). Built during the 13th, 14th and 15th centuries, it was the emblem and fortress of the dominion of the House of Mendoza in the highlands of Campoo.

Fontibre is a small town in the Brotherhood of Suso, just 5 km from Reinosa. Beautiful town and place, where the source of the Ebro River is traditionally located. In fact, the name Fontibre refers to the source of the Ebro, as it derives from the Latin Fontes Iberis ("sources of the Ebro") and is already cited by Pliny the Elder when he mentioned it. It is located near the Roman city of Julióbriga. It doesn't matter when you visit, or at the time of year, because you will always appreciate and enjoy this little walk through the place.
