Tijuana Estuary Visitor Center

Border Field State Park offers numerous horseback riding trails that are enjoyed by local equestrians, by riders from throughout San Diego, and by riders from neighboring counties.  During the summertime, this is the place to be.  You can ride horses on the beach, enjoy the thrill of walking your horse into the Pacific Ocean, and escape the inland heat.  Border Field State Park is one of the only places in California where equestrians can still ride horses along the beach.  If you are lucky, you might even see a pod of dolphins frolicking just beyond the surf. -more-
