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".

On the Puebla de la Sierra highway you come across this viewpoint over the Puebla river gorge. The landscape is overwhelming. The vertical walls of bare rock stand before the green ridges of the mountains and the sky. It is an ideal place to immortalize with a photograph.

This town of just over 100 inhabitants owes its name to the number of oaks and cistus that populate the area. Within its municipal term is the unpopulated area of El Villar (from which one of the Lozoya reservoirs takes its name). However, currently nothing remains of this place.
