Border Field State Park is on the very southwestern corner of the United States and 15 miles south of San Diego. Border Field is located within the Tijuana River National Estuarine Research Reserve, an important wildlife habitat. The sand dunes and salt marshes give refuge to critically threatened and endangered birds such as the Western Snowy Plover, the California Least Tern, and the Light-footed Clapper Rail.

The park provides restrooms, picnic areas, barbecues, horse corrals, and interpretive displays.  Visitors enjoy beach combing, hiking, horseback riding, and bird watching.  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. 

The Treaty of Guadalupe Hidalgo was concluded on February 2, 1848, officially ending the U.S./Mexico War. In 1850, delegations from both countries began surveying the boundary at this location.  Border Monument number 258 can be viewed from Monument Mesa, however there is no close access because it is now behind two border fences.

Why is the Entrance Gate Closed?

The entrance gate to Border Field is closed Monday - Friday. There is no vehicle access on those days.  California State Parks is implementing service reductions in order to meet Department budget cuts over the next few fiscal years.  Service reductions include limiting vehicle access to the park; however, the park remains accessible to pedestrians, bicyclists, and equestrians.  The park is closed to vehicle traffic most days during winter as rains cause flooding of park roads restricting access to Monument Mesa and other park features.  Read more about current status of vehicle access to the park.

Persons confined to wheelchairs may access portions of the park via the main road and an adjacent accessible path.

Pedestrians and Cyclists
The best way to reach Monument Mesa on foot is to park at the entrance gate lot, walk on the road and when the road turns, continue straight on the dirt path to the beach.  When you reach the beach, head south until you reach the border and Monument Mesa (distance = 1.6 miles).  It is advised to stay out of any puddles. 

Equestrians
Equestrians, please stage at the parking area at the entrance gate to the park.

California State Parks manages the Reserve and Border Field State Park out of the Tijuana Estuary Visitor Center, at the north end of the Reserve in Imperial Beach, California.  State Parks works in partnership with the U.S. Fish and Wildlife Service and the Southwest Wetlands Interpretive Association to conduct research, habitat restoration and education programs at the Visitor Center.  The Visitor Center is open to the public Wednesday through Sunday, 10am – 5pm.
