Loggerhead Key is the largest island of the Dry Tortugas. Covering about 49 acres, it is the site of the Loggerhead lighthouse, constructed in 1857. It was also the location of the “Tortugas Laboratory”, built and operated by the Carnegie Research Institute, for tropical research, from 1904 until 1939.
Little Africa, a reef, can be found at Loggerhead Key. At this snorkeling site you'll find even larger coral heads comprised of various species of stony and gorgonian coral. Living in and around the patch reef are different species of colorful, tropical fish, a variety of juvenile game fish and spiny lobster.
Limited to day use only, the Windjammer Wreck is a popular snorkeling Dry Tortugas site located just to the south and west of Little Africa Reef.
