Tips from the Community

August 9, 2026, Puerto de la Puebla

A very pleasant pass to climb up the Puebla de la Sierra side. To do this, you have to access it from Robledillo, with very steep ramps to warm up, and a few kilometers on a narrow and bumpy road. The views and the route are totally worth it. Avoid weekends, especially busy hours, as motorcycles, and especially cars, can spoil the party a bit, as I say, the road is very narrow. There is a fountain at the lowest point between Robledillo and Puebla, and another one when leaving Puebla de la Sierra. They are the only two points where you will be able to fill your bottles "for free".

The Castle and Walls of Buitrago del Lozoya, one of the most important medieval sites in the Community of Madrid: The town has pre-Roman roots and was mentioned by Livy as a Celtiberian fortress (Litabrum). Muslim Fortification: Between the 8th and 11th centuries, the Muslims built the wall to protect the territory. Reconquest: Alfonso VI conquered it in 1085, and it passed into Christian hands. Current Castle: Built in the 15th century by the Mendoza family, during the reign of John II of Castile. Historical Uses: Noble residence, defensive stronghold, and setting for events such as the imprisonment of Juana la Beltraneja.

Built of stone in 1936, it has an adjacent house constructed of the same material. It is surrounded by meadows in the heart of the village. Construction: Completed in 1936, it features a rustic and traditional design, in keeping with the local vernacular architecture. Historical curiosity: During its inauguration, a local resident entered the building announcing that the Spanish Civil War had broken out. Origin: Aoslos developed around an old hermitage dedicated to Saint James the Apostle, which was later deconsecrated. The holy water font, donated by a local resident, is still preserved from the hermitage. [horcajo-aoslos.com]
