Nature & Science

Dry Tortugas National Park lies at the farthest end of the Florida Keys, closer to Cuba than to the American mainland. To reach this remote ocean wilderness one must travel by boat or plane over nearly 70 miles of open sea. The park is home to historical and natural wonders above and below the water's surface and has long been an inspiration to visitors.
