Tips from the Community
This section of the Cañada Real Soriana Occidental retains its pastoral character. Grass grows in the surroundings and cows graze at will; the views of the Sierra de Guadarrama complete a beautiful bucolic scene.

From Puerto Linera, at 1834m altitude, you can see part of the Lozoya Valley, the Cabrera mountain range, highlighting the Pico de la Miel, the Riosequillo reservoir, Buitrado and Villavieja. Behind us is the province of Segovia, where we can see, among others, the town of Matabuena. The name "linera" is perhaps due to the large amount of linen that was sold from the Buitrago region to the towns of Pedraza and surrounding areas. The port has a cairn of stones much larger than those that delimit the terms, since, according to tradition, it was customary to throw a stone every time you passed from one side to the other to make it more visible when there was snow, blizzards or fog. , and prevent passers-by from getting lost.

The Port of Navafría is located between the municipalities of Lozoya and Navafría. With its 1,773 meters above sea level, it is considered a first-class port in the “Cycling Tour of Spain”.

Great views of the surrounding mountains here on this peak. If you are mountain biking, the La Horizontal trail is a good point to start or return to.
