Between the understated charm of Medinaceli and the railway heritage of Arcos de Jalón.

A journey through the Sorian countryside that follows the course of the River Jalón, flanked by imposing limestone cliffs in shades of red and ochre, between the austere beauty of Medinaceli and the railway heritage of Arcos de Jalón, with its iconic castle guarding the horizon. The route reveals traces of unique industrial and railway architecture, where iron bridges and tunnels carved out of solid rock take centre stage, and where it is well worth stopping at the natural lay-bys to watch the flight of the birds of prey that nest on the cliffs.
