The trail at the end of April 2026 is in good condition, the two streams to cross are short and have stones to pass. Via this trail you can get almost to Soto del Real avoiding the road through a beautiful environment.

Key Facts: Cela Sundial Location: It is located in the Pradera de Navarrulaque (Cercedilla), at an altitude of about 1,670 meters, right on the Carretera de la República. History: Inaugurated in 1995, it is a tribute to the writer (a great lover of the mountains and author of Cuadernos del Guadarrama) and to the first hikers who traversed these mountains. Curiosity: It is an analemmatic sundial. This means it does not have a fixed needle; you are the clock yourself. You have to stand on the current date marked on the ground, and your own shadow will indicate the time on the stone pieces surrounding you. Surroundings: It is on a beautiful route that passes by the Ducha de los Alemanes and the Miradores de los Poetas. I love this sundial in honor of Cela. It's super original because you interact with it to know the time. It's in a privileged spot in the Sierra de Cercedilla, surrounded by pine trees and with a lot of peace. A "rural monument" with a lot of charm that I never tire of visiting on my hikes through the Valle de la Fuenfría.

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 name comes from the stone boundary markers erected in the 18th century to demarcate lands acquired by Charles III for hunting. During the Spanish Civil War, it was a strategic area with a Republican detachment stationed there. It formerly housed the Valcotos ski resort, which no longer exists.
