Oct. 1, 2016: The Sand Key Lighthouse 7 miles off of Key West is often full of seabirds, including pelicans, magnificent frigatebirds, cormorants and terns. The structure itself has been part of several amazing history tales, including an 1846 tragedy, when a hurricane obliterated it along with the keeper and his family. Today the snorkeling here is among the best in the Keys, thanks to its super-shallow structure and vibrant marine life. Often seen here is everything from sea turtles to parrotfish, barracuda to anglefish. Read about both in our Key West & the Lower Keys Travel Guide, available on amazon.com.
