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.

One of the few towns on the greenway to grab a drink (aka a bar) between Poza and Burgos. A must-stop for a rest.
