Wilderness Landscape & Natural Heritage
Chino Hills State Park covers a broad area of gently rolling hills and open space within the eastern edge of Orange, Riverside, and San Bernardino counties in California. Established in 1981, it provides over 14,000 acres of preserved open space in the rapidly developing region of Southern California. The park's geography consists of grassy hills, oak woodlands, riparian corridors, and chaparral ecosystems. These diverse habitats support a wide variety of wildlife, including mule deer, coyotes, bobcats, and numerous bird species such as red-tailed hawks and California quail. Historically, the land was utilized by Native American tribes such as the Tongva and Serrano, and remnants of early ranching and agricultural use can be found within the park. Visitors enjoy more than 60 miles of trails that provide ample opportunities for day hiking, mountain biking, horseback riding, and primitive camping. Notable trail sections include the gently sloping Blue Sky Trail and the more challenging Overlook Trail, both offering panoramic views of the park’s hills, the Los Angeles Basin, and the San Gabriel Mountains. The park serves as an important wildlife corridor connecting larger wildlands nearby and offers urban visitors a natural refuge for outdoor recreation and education. With picnic areas, trailheads, and a small visitor center, Chino Hills State Park attracts a steady stream of outdoor enthusiasts seeking scenic open space near the Los Angeles metropolitan area. Its relative proximity to urban centers combined with diverse terrains and native plant communities makes it an appealing destination year-round.
