Padre Island National Seashore separates the Gulf of Mexico from the Laguna Madre, one of a few hypersaline lagoons in the world. The park protects 66 miles of coastline, dunes, prairies, and wind tidal flats teeming with life. It is a safe nesting ground for the Kemp's ridley sea turtle and a haven for over 380 bird species. It also has a rich history, including the Spanish shipwrecks of 1554.
