The Florida Keys consist of about 882 islands that begin about 15 miles south of Miami and extend in a southwestward arc toward Key West. Key West, the most renowned, largest and farthest west inhabited island, is home to what is considered the southernmost point in the continental U.S. and hosts about 1.6 million visitors a year.
Pictured is the Flagler Trestle Railway, built in the early 1910s by an ambitious developer of Florida's Atlantic coast — Henry Flagler. Previously, the Keys were only accessible by water. The railroad was destroyed by a hurricane in 1935, but sections like this one still remain.
