A small coastal estuary located south of Imperial Beach and one of the few salt marshes remaining in Southern California. Next to the estuary at the USA-Mexico border is '''Border Field State Park''', which covers the extreme southwestern corner of the United States, where the USA-Mexico border meets the ocean. Border Patrol officials keep a close eye on this area.
Located on the Silver Strand, this is an excellent beach to swim or surf at. RV camping and fishing are allowed here.
