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.
