Fort Jefferson Loop, Dry Tortugas National Park, Florida, USA
You won’t find any wilderness hiking trails in Dry Tortugas, an island 70 miles west of Key West. The main attraction here is Fort Jefferson, the largest masonry structure in the Western Hemisphere. A half-mile loop around the island is a great tour of the fort and overlooks the Caribbean’s crystal waters.
