Most cities surrounding Chino Hills State Park do not allow fireworks and neither does the Park. The weeks before and after the Fourth of July have the most incidents of illegal fireworks starting fires in the Park. Please report any suspicious or illegal activities in the State Park by calling 911. Report that it is occurring in Chino Hills State Park. You should be transferred to the Park’s Emergency Dispatch Center, which is where you’ll report the location of the incident (e.g. South Ridge Trail, etc.) Our Park’s habitat, trees and wildlife can’t handle the frequency of fires we are seeing – especially when compounded by drought. Please do your part to stop the fires from even starting.
