Alto del León from Guadarrama is fairly consistent, with just a few steep corners on the hairpin bends.


Roads & Traffic

The road is in good condition throughout.

This is a very busy climb, with a lot of heavy goods vehicles and other fast moving traffic. It makes for an unpleasant ride.


Climb Description

The Alto del León is a pass in the Sierra Guadarrama mountains, linking the provinces of Madrid and Segovia. It is a climb which has been used in the past during the Vuelta a España, but we strongly advise against cycling it.

It is the main non-toll route between Madrid and the north-west of Spain and carries a lot of heavy traffic. The road is wide, but it is both unpleasant for cycling and dangerous. The scenery is also not particularly inspiring, with the road in dense forest throughout the climb.

Alto del León is kept open throughout the year.


Other sides

Alto del León can also be climbed from the north, starting in San Rafael. The road is just as busy from this side and should also be avoided on a bike.


Tours
