Chino Hills State Park is a 14,000-acre protected wilderness area featuring rolling grassy hills and deep canyons within the Santa Ana Mountains range. The park preserves a significant portion of the Puente-Chino Hills biological corridor, serving as a critical link for wildlife movement between the Santa Ana Mountains and the Chino Hills. Visitors utilize over 90 miles of trails designated for hiking, mountain biking, and horseback riding. The landscape is characterized by coastal sage scrub, chaparral, and riparian woodlands that support diverse fauna including bobcats, mountain lions, and coyotes. During spring months, the hillsides often display extensive wildflower blooms, particularly California poppies. The topography ranges from 430 to 1,781 feet in elevation, providing extensive views of the surrounding urbanized inland valleys. The park acts as a natural buffer against suburban sprawl in the surrounding Chino Hills and Brea areas. Several seasonal streams flow through the park's canyons, providing essential water sources for local wildlife populations.
