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.

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.
