The best road cycling routes around Hermandad De Campoo De Suso

Here is the "official" source of the Ebro, even though it was proven about 40 years ago that only the water of the Rio Hijar, which seeps away at Paracuelles, re-emerges here. Strictly speaking, it is a karst spring. Not far below the spring, the Ebro is dammed by a small weir, creating a beautiful little pond here, which is obviously also popular with ducks. The circular path around the pond from the spring to the weir is only a few hundred meters long walk, a large visitor car park is directly above, so you don't have to make a long hike to visit - but you can, of course, also start the GR99 here and walk to the Mediterranean...

The Plaza de España in Reinosa is, like in so many others, a meeting place and a venue for celebrations. Don't miss visiting it and, if you have time, relaxing on one of its terraces trying some of the local tapas.

A beautiful architectural ensemble: a square, a church, and the priest's house on the banks of the Ebro River, which, in this section, is no more than 40 cm deep!

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.

Interesting to visit, if you are in the area.

Here you can find the poultry facility, dedicated to the production of free-range eggs and products from the Cantáfrica association's garden.

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.
