The Roman Road has been dug up in places & only close to the highest point of any Camino in Spain the Pass of Fuenfria 1796 mts it remains intact. Hard 30kms a fantastic stage with amazing views to the peaks of the Sierra de Guaderrama which I have climbed & when it culminates in a city like Segovia it's really hard to beat. Definitely ranks as one of the many memorable days of the fourteen Caminos I have done, Buen Camino
