Are there any new visitor guidelines?
State Parks has implemented the following guidelines to reduce the risk of exposure to COVID-19 in the outdoors:

  • Plan Ahead
    • The ongoing pandemic response continues to be dynamic and fluid. Prior to leaving home, check the webpage of your outdoor destination you plan to visit to find out if it is open, if parking is available, and what visitor guidelines are in effect.
    • Learn what safety precautions you should take when exploring the outdoors at
  • Stay Safer at Six Feet: No matter the recreational activity, maintain a physical distance of six feet or more. Your guests should only include those within your immediate household. This means no guests or friends, and no gatherings or parties. If there are too many people to maintain the required physical distance, please visit us on a different day. 
    • Boating: Do not raft up to other boaters or pull up onto a beach next to other recreators.
    • Off-highway Vehicle Recreation: Do not ride next to others or pull up next to someone else as it could put you in close proximity to others. Stage 10 feet or more from each other during unloading and loading.
  • Keep Clean: Be prepared as not all services may be available. Some restrooms will be temporarily closed to keep up with cleaning schedules. Bring soap/hand sanitizer. Please pack out all trash. Park units are experiencing heavy use and you can help alleviate the impact on park facilities.
  • Stay Covered: The state requires you to wear a face covering when you cannot maintain a physical distance of six feet or more. Individuals must have a face covering with them at all times.

Although law enforcement entities have the authority to issue citations, the expectation is that the public is responsible for adhering to the advice of public health officials, visitor guidelines and closures.

California State Parks continues to work with local and state officials on a phased and regionally driven approach to increase access to state park units where compliance with state and local public health ordinances can be achieved. However, the situation remains fluid and park operations can change at any time. For information on statewide current closures and available services, please visit

Border Field State Park

Located within the Tijuana River National Estuarine Research Reserve, Border Field State Park sits in the very southwestern corner of the United States, 15 miles south of San Diego. This important wildlife habitat, comprised of sand dunes and salt marshes, gives refuge to critically threatened and endangered birds such as the Western Snowy Plover, the California Least Tern, and the Light-footed Ridgway's Rail.

The park provides restrooms, picnic areas, barbecues, horse corrals, interpretive displays, and scenic views across the beach and estuary. Visitors enjoy hiking, horseback riding, photography, and bird watching along the 1.5 mile stretch of beach and inland trails. The Park does not recommend swimming or wading, due to hazardous conditions, such as inshore holes, rip currents, and the lack of lifeguard service within the Park. 

Border Monument number 258 can be viewed from Monument Mesa, however there is no close access because it is now behind two border fences. You can still see the bunkers which were leftover from World War II. Read more about the history of this area.

Access to the Border Monument at Friendship Circle

Friendship Park is currently closed. For more information, please contact the Border Patrol Public Information Office: 619-216-4182.
