About Border Field State Park Beach in San Diego, California

The beach at Border Field State Park is the southernmost beach in California. This beach starts at the Mexican border and continues north to the mouth of the Tijuana River. Because the river is too high to wade across and is backed by wetlands, it requires driving around the estuary to reach the beach at Border Field State Park.

Border Field State Park and the adjacent Tijuana River National Estuarine Research Reserve are jointly managed by the state of California. For information about this unique state park and the reserve, stop into the Tijuana Estuary Visitor Center located at 301 Caspian Way in Imperial Beach.

Monument Mesa in Border Field SP is located in the southwest corner of the park next to the border fence. This developed area has picnic areas, BBQ grills, restrooms, a grass park, and accessible trails. Unfortunately the Border Field State Park roads and entrances are regularly closed due to flooding, especially in the winter months, so check ahead for their status. Even when the roads are in good shape the state park typically only opens the gates on the weekends. If gates are closed to vehicles, then you can still park near the gates and walk into the park during daylight hours. It’s about a mile from the entrance gate to the beach straight ahead.

To get to Border Field State Park, drive south on I-5 from the San Diego area and then take the Dairy Mart Road exit and drive west to the end (it becomes Monument Road). Signs spell out warnings of sewage contamination in the ocean water so do not swim here.

When Border Field State Park is closed, a good alternative beach is on the other side of the river mouth at Tijuana Slough National Wildlife Refuge which can be reached from the end of Seacoast Drive in Imperial Beach.

This is a wonderful beach that is underused because it’s hard to get to. Currently the park is closed due to damage from the hurricane. From the State Park website: Effective August 20, 2023: Border Field State Park will be closed due to damage from Hurricane Hillary and cross-border flows related to failure of wastewater treatment plant infrastructure on the border. The roads and trails may be flooded with sewage contaminated water and mud. Out of precaution and public safety, the park is closed to hiking, biking, equestrian activity and vehicles until further notice.
