The waterfall springs from the Cueva del Agua from a height of over 20 meters, at the base of the rocky cirque that embraces the village, originating from an aquifer located in the subsoil of the Páramo de Bricia, and it leaps everywhere, dividing the village into two halves, the Villa and the Puebla, and descends among the stone houses, creating a most photogenic scene.

You might not want to go up to the village because you're too lazy, but once you get there, I assure you, you won't regret it. You can walk up the stairs or bike along the road from the village exit (heading upriver). It's clear that this is a tourist destination because it's home to most of the area's bars and restaurants.

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.

Very nice and comfortable route, there is a stretch of about 6km of narrow road and the vehicles do not respect it.
