Chino Hills State Park is unique in that it provides refuge for both biodiversity and solitude to the visitors who enjoy their outdoor experiences. There is no other location in the LA Basin were people can drive a short distance and be swept away with scenic vistas, hike, bike or ride a horse on over 90 miles of trails. At 14,102 acres the park is managed as an open space habitat where all plant and animal life are protected.
When the park is open most trails are available with the exception of Hills for Everyone Trail, which is closed due to severe erosion and fallen trees onto the trail. North Ridge Trail is closed between where it intersects Telegraph Canyon Trail to Gilman Trail. Currently Gilman Peak is accessible only by using the Gilman Trail, Sycamore Trail, or McDermont Trail from the Telegraph Canyon Trail. The portion of North Ridge Trail which is affected is closed due to severe erosion.
To protect the natural resources in the park and keep visitors from harm, the trails can be closed temporarily when adverse conditions such a significant rain occurs. The trails will close for approximately 48 hours after rain level amounts of 1/4 inch or more. Trails will also close when the National Weather Service indicates Red Flag conditions for the region which includes Chino Hills State Park. Access into the park and park trails is prohibited when the park is closed. Signs will be posted at the legal entrances into the park, this webpage will be updated as well as the Chino Hills State Park Facebook page. We appreciate your cooperation and assistance in protecting the park and providing a safe place to recreate.

EMERGENCIES AFTER THE PARK IS CLOSED – CALL 911
Information regarding the gate closure is available at the park and online at the State Park website. While some campers may be inconvenienced by the nightly closure, an extra level of security is provided by eliminating vehicles driving in the park that are not associated with campers. Not having these vehicles in the park at night reduces the hazard to children and pedestrians, reduces noise and vandalism, and reduces opportunities for theft of camping gear.
Campfires - ARE NOT PERMITTED As of May 21, 2012
Park Closure - The park will close for at least 48 hours following rain of more than one quarter inch. High clay content in the soil causes “greased” trails and roads. Use during this time makes hiking, bicycling and equestrian activities hazardous and causes severe rutting of trail and road surfaces. The park is also closed during times of extreme fire danger, when the National Weather Service announces a Red Flag Warning.
Trails - For safety’s sake, stay on designated trails and don’t hike alone. Be aware of wildlife, especially rattlesnakes.
