A Roman path to Puerto de la Fuenfría
Puerto de la Fuenfría is a high mountain pass at an elevation of 1.796m (5,892ft) above the sea level, located on the boundary between the Autonomous Community of Madrid and the province of Segovia, in the central part of the country.
Tucked away in the Sierra de Guadarrama (mountain range of the Central System), the road to the summit is totally unpaved and closed to private motor vehicles. Access to the pass is typically open all year round, with the occasional closure in winters due to dangerous weather conditions. The road is pretty steep with an average gradient of 10%.
The road starts on a parking lot called Parking Majavilan and follows a Roman path (Republic Road), which was heavily used until 1788, when the Navacerrada Pass was opened.
