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.

Of great beauty and easy to access (be careful, there are some winding stairs) they are one of these little-known corners of Madrid. In the bed of the Guadalix River and almost at the mouth of its spectacular canyon, the waterfall depends on the opening of the reservoir, upstream, which guarantees water flow practically all year round.

The Hermitage of San Blas, more than a hermitage, could be said to be a humiliation, a holy place in the cattle pastures at the foot of the Najarra in Miraflores de la Sierra, composed of a small stone wall supported by a porch that houses the image of Saint Blaise, a saint known for his miraculous healings. The hermitage is located on a promontory surrounded by the granite bowls so characteristic of this part of the Sierra de Guadarrama, from its position there is a viewpoint with beautiful views of such characteristic places as La Pedriza, Cabezas de Hierro, the Santillana reservoir and in the distance the Madrid skyline with the 4 towers. A perfect place to stop and contemplate the immensity of that land and the tranquility that can be breathed from there, observing the silhouette of the great city in the distance.
