La Pedriza is a maze of granite boulders, domes and rock towers in the Sierra de Guadarrama National Park. The park's visitor center sits at its entrance, with an exhibition on the sierra and a two-hectare garden holding a rock garden, a mini Pedriza, a bird hide, an aquarium and a reptile and amphibian center. Trails into the rocks start just past the barrier.
