January 9, 2026, Castillo de Manzanares el Real

Manzanares el Real Castle, also known as Mendoza Castle: Built in 1475 by order of Diego Hurtado de Mendoza, 1st Duke of the Infantado, on the site of a former Romanesque-Mudéjar church. Its architecture is Isabelline Gothic, with a square floor plan, cylindrical towers, and an octagonal keep. It served as the palatial residence of the powerful Mendoza family, who even established a literary court there. Declared a Historic-Artistic Monument in 1949. Today it houses a Medieval Interpretation Center, with exhibits of tapestries, armor, furniture, and audiovisual presentations about life in the Middle Ages.

A comfortable trail with incredible views. As an added bonus, you can descend to the Mojonavalle waterfall. A truly beautiful cascade.

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.

A beautiful bridge leads to the Finca de los Batanes, where the hostel is located. Opposite is the El Paular Monastery. From this bridge, there's a path that leads to the village of Rascafría, where I could see people walking and exercising.

It is a good area for a quiet route without rushing... except for some sections with a lot of water where you have to walk.
