The Descalzo Bridge is one of the best-known bridges on the Fuenfría Roman Road in Cercedilla. Although long attributed to its Roman origin, more recent research suggests that, although the road crossed here in Roman times, the bridge itself may have been built or heavily modified in the 18th century (Bourbon era). Despite this, it is located on an important section of the Roman road that connected Segovia with Titulcia and has been restored several times, maintaining its original structure. It is a masonry bridge with a single arch and blends perfectly into the natural surroundings, being part of a popular hiking trail in the Sierra de Guadarrama. Both the bridge and the road have been declared a National Historic, Artistic, and Archaeological Site.

Be careful with the cows, bulls and their calves that graze in the meadow, on the mountain and on the slope. You will see their excrement on the path and you will hear them from afar because of their bells, but seeing them will be more difficult among the undergrowth and rocky obstacles. Be careful, leave them alone and go around the area where they are.
