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. Border Field State Park and the adjacent Tijuana River National Estuarine Research Reserve are jointly managed by the state. For information about the state park and the reserve just visit 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 here, 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.
