Scheduled Campground Closure:
Chino Hills State Park has a scheduled campground closure in place for July 15th - November 30 2019 to accommodate a water line project.
During this time, the campground will be closed to all camping and day use visitors. The closure will also affect access to Ranger Ridge Trailhead leading from above the campgrounds. We apologize for any inconvenience this may cause.
Any further questions can be directed to our Sector Office at 951-780-6222.
You can find a map of the project affected areas HERE
The gates are locked in the evenings during the following hours:
- 5:00pm October 1st - 1st Sunday in April
- 7:00pm 1st Sunday in April - September 30th
Gates open at 8:00 am.
When gates are locked, there is no vehicle access into or out of the campground.
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.
