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.

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.
