Padre Island National Seashore

A beach is a beach is a beach? Not so. Padre Island National Seashore is the largest undeveloped, untouched barrier island, not just in the United States but in the world!  It’s long enough and isolated enough that, after even a modest drive, you are truly on your own: no mobile telephone services, and indeed no other human beings for 30+ miles in any direction.
