Cuyamaca Rancho State Park is a state park located forty miles east of San Diego, California in the Peninsular Range. The park's 26,000 acres (105 km) feature pine, fir, and oak forests, with meadows and streams that exist due to the relatively high elevation of the area compared to its surroundings. The park includes 6,512-foot (1,985 m) Cuyamaca Peak, the second highest point in San Diego County, as well as an exhibit at the Stonewall Mine, a former gold mine. Park services include trails for hiking, horseback riding, and mountain biking, as well as campgrounds for family, group, equestrian, and primitive trail camping. Wildlife in the area includes mountain lions, which have been known to attack humans, and park literature emphasizes avoiding encounters with them. Numerous other species of mammals, birds, reptiles, and amphibians are known to reside within the park.
