Overview

Cidacos Valley & the Enciso Dinosaur Route — Calahorra to Enciso.

A ride up the Cidacos into the Rioja Baja, the quieter, wilder southern side of La Rioja. From the Roman city of Calahorra the LR-115 climbs past the cave-riddled cliffs of Arnedo to the spa village of Arnedillo, then up a narrowing gorge to Enciso, home to some of the best-preserved dinosaur trackways in Europe. Griffon vultures ride the thermals overhead the whole way. Ridden as an out-and-back up the dead-end valley.
