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.

The Aguilar reservoir, inaugurated in 1964, plays a crucial role in regulating the Pisuerga River. With a height of 48 meters and a length of half a kilometer, the dam is one of the largest in the area. It is part of a set of three reservoirs and is considered a tourist attraction thanks to the "Ruta de los Pantanos".

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.

Located between high mountains far from the sea, the fascinating thing about this city is that it dates back to the Middle Ages, with an old town with interesting monuments to visit. The structure that stands out the most is the church of San Sebastián in the old center of the city. Furthermore, in the Town Hall Square you can see a set of ashlar buildings, built in the 16th and 17th centuries. Don't forget to try the city's most typical sweet, calf, which is a puff pastry with caramelized sugar.

The name Fontibre refers to the source of the Ebro – it derives from the Latin Fontes Iberis ("sources of the Ebro"). Fontibre is famous for having traditionally located the source of the Ebro river here, despite the fact that, in scientific terms, this is not exact. It is now known that the main source of the waters of the Ebro River is the Híjar River. By visiting the Visitor Center in the town, you can learn about the cultural, social and landscape diversity that the Ebro River has generated throughout history.
