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.

Poetry with the best views of the sierra Climbing up to the Mirador de Vicente Aleixandre is, for me, one of the most inspiring experiences in Cercedilla. It's not just the hike through the Valle de la Fuenfría, which is beautiful, but the moment you reach that rock and read its sculpted verses while contemplating Siete Picos. You breathe in an incredible peace. It's the perfect place to stop, sit down to rest, and feel part of the landscape that the poet loved so much.

Exceptional water, which even people from the village come to collect.

The Vicente Aleixandre viewpoint, or Poets' Viewpoint, offers an unbeatable view of the entire mountain range. Cercedilla lies at our feet, the Bola del Mundo peak rises above, and some verses are engraved on the rock to commemorate the recitals that were once held there.

Beautiful place to the left of the Fuenfría valley. A hill that reaches a height of 1750 m. and which is located between Peña Bercial and Peña del Águila.

It is halfway up the climb to La Peñota, so it is a good point to stop on days without a storm. On stormy days it may be too exposed to the wind to make a stop at this hill.
