At over 24,000 acres, this is the largest urban park in the US. It's a quick escape from the city to the home of ringtail cats, coyotes and countless other smaller animals and reptiles. There's excellent mountain biking and hiking here, with 7192ft North Franklin Peak looming overhead.

Head to the visitor center to get a basic park map, written descriptions of the hiking trails, mountain-bike trail maps, or route maps of the 17 different rock-climbing routes.
