To see a current list of impacted parks, visit www.parks.ca.gov/flattenthecurve. For those wishing to take a break in the outdoors, public health officials are advising them to walk, run, hike and bike in their local neighborhoods and walk to parks. Most importantly, the public is being asked not to congregate in the outdoors.

Visitors are reminded to practice social distancing and maintain at least six feet between other visitors and anyone who is coughing or sneezing. Restrooms also remain open, and visitors are advised to take soap for hand washing and alcohol-based hand sanitizers when water is not available.

State Parks recommends that everyone follow precautionary guidance issued by the California Department of Public Health, public local health agencies, the Governor’s Office of Emergency Services and the Centers for Disease Control and Prevention when recreating in the outdoors. Everyone has the responsibility to “flatten the COVID-19 curve at Parks” by maintaining a social distance of 6 ft. or more when recreating in the outdoors, and staying home if they are sick. If visitors cannot maintain social distancing, they need to leave the park.
