What Is It?

Dry Tortugas National Park is known worldwide as the home of magnificent Fort Jefferson, blue waters, coral reefs, marine life and a vast assortment of bird life.



Designated by President Franklin D. Roosevelt under the Antiquities Act of 1935, Fort Jefferson National Monument was expanded in 1983 and redesignated as Dry Tortugas National Park in 1992. Dry Tortugas was established to protect the island and marine ecosystems, to preserve Fort Jefferson and submerged cultural resources such as shipwrecks, and to allow access in a regulated manner.
