Boca Chica State Park

Boca Chica is an area on the eastern portion of a subdelta peninsula of Cameron County, at the far south of the US State of Texas along the Gulf Coast. It is bordered by the Brownsville Ship Channel to the north, the Rio Grande and Mexico to the south, and the Gulf of Mexico to the east. The area extends about 25 miles east of the city of Brownsville. The peninsula is served by Texas State Highway 4—also known as the Boca Chica Highway, or Boca Chica Boulevard within Brownsville city limits—which runs east–west, terminating at the Gulf and Boca Chica Beach.

The Boca Chica area has seen various developments over the course of its history. These include Mexican land grants, Mexican and American ranches, a battlefield of the American Civil War, a 1920s beach resort, and a state park; additionally, a small settlement named Boca Chica Village existed in the area from 1960 to 2020.
