Padre Island National Seashore separates the Gulf of Mexico from the Laguna Madre, and protects coastline, dunes, prairies, and wind tidal flats.
Padre Island National Seashore, encompassing 130,434 acres, is the longest remaining undeveloped stretch of barrier island in the world, and offers a wide variety of flora and fauna as well as recreation.
Padre Island National Seashore is the most important nesting beach in the U.S. for the Kemp's ridley, the most endangered sea turtle in the world. The National Seashore has been a participant in a bi-national, multi-agency effort to save the Kemp's ridley sea turtle since 1978. The park also participates in global efforts to recover the populations of four other threatened and endangered sea turtle species.
