Lermilla, with a spectacular rest area!

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.
