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.

The Serranillos Pass is one of the most iconic mountain passes in the Sierra de Gredos, famous for its beauty and for being a historic stage in the Vuelta a España (Hinault's legendary stage in 1983). Views of the Cinco Villas Valley and the Gredos peaks. Spectacular scenery throughout the climb. Signage with gradient and remaining distance information. Ideal for linking up with Puerto del Pico, Pedro Bernardo, and Mijares for an epic stage.

The Mijares Pass is one of the great mountain passes in the Sierra de Gredos, highly prized by cyclists for its length, elevation gain, and scenic beauty. Maximum gradient: 11% (on short ramps before Mijares). There are several steep sections in the villages and near the Horcajo area, as well as another one 2 km from the summit.

The Pedro Bernardo Pass is one of the classic climbs in the Sierra de Gredos mountains, highly prized by cyclists and a regular feature of races like the Vuelta a España. First section: Up to the village (Pedro Bernardo), with gradients of 5-6%, a road in good condition, and spectacular views of the Tiétar Valley. Urban section: In the village, the gradient eases, even offering some flatter sections. Second section: After the village, the asphalt becomes rougher, and the toughest kilometer (7-8%) appears, followed by a "balcony" section with incredible views and a sustained 5% gradient to the summit.

You cool down very quickly up here, especially when it's windy.

A legendary mountain pass in the Vuelta a España and in the Gredos mountain range, along with Serranillos, Peña Negra, Pedro Bernardo, and Puerto del Pico. It's a namesake of Serranillos, as it connects the same valleys, running parallel. Like Serranillo, it's a pass with a gentle, continuous gradient and uneven, bumpy asphalt, which is typical of this area. A pass of thermal contrasts: in winter, you're freezing cold, and in summer, you can die of heat.
