The Chino Hills State Park is part of a larger bio-link known as the Puente-Chino Hills wildlife corridor. For the plants and animals in the Chino Hills State Park, this area is an important link to other natural open space areas. The Water Canyon Natural Preserve and Coal Canyon Preserve areas of the park make up a biological corridor that allows wide-ranging species of native wildlife like bobcats, mountain lions, deer, coyotes, and a variety of other rare species to avoid becoming trapped in isolated patches of open space habitat. Coal Canyon is one of the greatest conservation stories in all of Southern California.

Coal Canyon used to be all asphalt as it was an exit from the 91 freeway. More than a thousand residential homes along with a commercial center with a gas station and restaurants were slated for development at the Coal Canyon exit. But those plans were abolished when scientists realized that a mountain lion they had been tracking was using the underpass to cross under the 91 freeway and move between suitable parts of his habitat in the Santa Ana Mountains (Cleveland National Forest) and the Chino Hills State Park. Coal Canyon remains the only place wildlife can move between the Santa Ana Mountains and the Puente-Chino Hills wildlife corridor. When land on both sides of the freeway was added to Chino Hills State Park in 2000-2001, this became the first time in California history that land was saved because of its connectivity value. The underpass is now a wildlife corridor for many animals and has been restored to its natural state. For more information on preserving bio-links in the Puente-Chino Hills make sure to check out Hills for Everyone.

The Chino Hills State Park ranges from 430 feet in elevation all the way to 1,781 feet in elevation. The park straddles the north end of the Santa Ana Mountains and the southeast portion of the Peunte-Chino Hills. More than 200 species of birds and mammals, numerous reptiles and amphibians, and invertebrates live in the park. Sadly, this area still shows evidence of the 2008 Triangle Complex fire that ravaged the Chino Hills State Park. However, the park appears to be recovering nicely. If you do this hike during a warm summer day make sure to bring plenty of water and wear sunscreen as there is limited shade along portions of the trail.
