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.

It's a very quiet pass with hardly any traffic, especially in its final section. The eastern slope, which starts from Arenas De San Pedro, has two very distinct sections. The first, to the village of El Arenal, is very gentle and always runs under an extensive pine forest. When you reach El Arenal, in the village itself, the gradient increases, and then there are 6 km left with an average gradient of 7% and some 10% slopes. The views from the pass are beautiful and it exudes a spiritual tranquility. In summer, it's highly recommended to climb it early in the morning to take advantage of the cool morning air. The western slope connects with the climb to Puerto del Pico, and the climb begins in Ramacastañas. Although not as well-known as other passes in the Sierra de Gredos, I have to admit that I loved it.
