The route

Loop no. 10 of the mountain bike network of the Sierra de Guadarrama National Park, heading to the Hueco de San Blas, the valley that opens up below the Cuerda Larga between Manzanares el Real and Soto del Real. Dirt tracks and paths with stony sections and an elevation you'll feel in the second half. You'll want a mountain bike or a gravel bike with good grip. In winter the upper part can be icy first thing in the morning; spring and autumn are its best seasons. Bring water and something to eat: there are no bars along the way, only in the villages at the start. Respect the livestock and close any gates you open.

Track based on OpenStreetMap (MTB network of the Sierra de Guadarrama National Park, route no. 10) (ODbL).

Before you set off, check the state of the road or track and follow the traffic rules. Enjoy the ride.
