You can climb some of the tallest limestone cliffs (1,000 feet) in North America at El Potrero Chico. The tallest is the North Face of the Mountain of El Toro, which is just about 2,000 feet. The well-bolted, multi-pitch sport routes offers the experience of a lifetime. One of them is the second longest in the region. The climbs have very easy access with only a 5-minute walk from most campgrounds, eliminating any need for a car. The best time to visit is in the spring and fall.
