Loggerhead Key

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.

Loggerhead Key allows public access 365 days of the year, but unlike Garden Key, it's restricted to day to dusk activities only.
