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.
