March 30, 2026, Toros de Guisando

Los Toros de Guisando are a set of zoomorphic sculptures of Vettonian origin, carved in granite between the 4th and 2nd centuries BC. They probably represent bulls or verracos and were linked to rituals for the protection of livestock and the delimitation of territory.

A nice climb from the El Burguillo reservoir. The first part is asphalt in very good condition (as of November 1, 2025), and the second part is a dirt track, also in very good condition. It's a demanding climb; the asphalt section offers some flatter sections, but the dirt track is practically a continuous gradient of around 10%.

Beautiful road alongside the reservoir, very quiet. It has no paved exit.

Beautiful stone bridge over the Alberche River as it passes through Navaluenga.

The arrangement of the sculptures is interesting: they are side by side, forming a line in a north-south direction and all of them facing west, to the hill of Cerro de Guisando, from which they receive their name. The Tórtolas stream, which is located behind it, marks the natural border between the communities of Castilla y León and Madrid.

It is a place where you can admire stone carvings that are more than 2,000 years old that were recovered and taken there so that they can be contemplated by visitors who wish to do so. You have to pay a small entrance fee of €2 to ensure the conservation and maintenance of the sculptures, but it is definitely worth it. These are 4 bulls carved in stone from the 3rd century BC. next to an old inn or inn called "Juradera" in which the pact was signed between Enrique IV and his sister Isabel.
