A very pleasant pass to climb up the Puebla de la Sierra side. To do this, you have to access it from Robledillo, with very steep ramps to warm up, and a few kilometers on a narrow and bumpy road. The views and the route are totally worth it. Avoid weekends, especially busy hours, as motorcycles, and especially cars, can spoil the party a bit, as I say, the road is very narrow. There is a fountain at the lowest point between Robledillo and Puebla, and another one when leaving Puebla de la Sierra. They are the only two points where you will be able to fill your bottles "for free".

Watch out for the asphalt on the descent, there are potholes and the surface is quite uneven. You won't even notice it on the climb.

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.
