La Pedriza is the so-called extensive natural reserve, stretched in a picturesque mountain valley along the banks of the Manzanares River. The area is a popular site for hiking, mountaineering, and above all—climbing and bouldering. It's listed among the top destinations for rock climbing found in Spain overall.
In fact, you may climb in La Pedriza all year round but the best seasons are still moderate spring and autumn. If you choose winter, be ready for rain, fog, and snow. In the hottest months of July and August, you should do it in the late afternoon, for the ruthless sun will surely burn your skin.
