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.

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.

From the Puente de la Cantina (Cantina Bridge), ramps of 6-7% begin. Between km 6 and 8 are the five tightest bends, almost linked together, in a wooded area. The final kilometer has a steep ramp before reaching the summit.
