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.

The Puerto de Pedro Bernardo is the younger brother of the Puerto de Serranillos. Almost every time this port has been climbed in a professional race it is linked to the Puerto de Serranillos, only the second being considered a port. However, the Puerto de Pedro Bernardo is in itself a hill where you can go from the valley where the CL-501 road runs (where the town with the same name is located) to the valley of the Puerto de Pico, where Esteban del Valle and Mombeltrán are located. The chain with Serranillos is the most typical, as I said previously, although it is also worth chaining it with the Puerto de la Centenera or the Puerto del Pico. The road is rough, with hardly any shoulder and very little traffic. It is a very pleasant port to climb... as long as the heat is not suffocating.

Castle built in the 15th century. In the year 1393, King Henry III granted the title of Villa to Arenas de San Pedro, handing over its lordship to Ruy López Dávalos, constable of Castile, who began its construction. It is known as the Castle of the Sad Countess, because after the execution of Don Álvaro de Luna in 1453, Juan II allowed the town to remain in the possession of his widow, Doña Juana de Pimentel, popularly known by this nickname.
