A scenic paved road to Puerto de Navafría
Puerto de Navafría is a high mountain pass at an elevation of 1.775m (5,823ft) above the sea level, located on the boundary of Castile and Leon and Madrid, in central Spain.
Located in the Sierra de Guadarrama, the winding road to the summit is paved but narrow and bumpy, with some steep sections, hitting a 10% through some of the curves. It’s called M-637 (southern side) and SG-612 (northern side).
Open to traffic throughout the year, may be closed for short periods in winter when the weather is bad. Surrounded by trees, the drive offers great panoramic views. At the summit there’s a ski station. The climb has been used by the Spanish Vuelta race. The pass is 23km long running north-south from N110 Road (on Navafría) to M604 (on Lozoya).
