Lermilla, with a spectacular rest area!

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.

Built to span the Ebro River, this stone bridge is an impressive 143 meters long and features nine arches. The central section boasts a slender defensive tower, adorned with battlements and arrow slits, added in the 14th century. In medieval times, passage was controlled from this tower: anyone wishing to cross the bridge had to pay a toll of a few maravedís. The bridge offers one of the best views of the city of Frías.

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.
