Dry Tortugas National Park

Dry Tortugas National Park

Where history meets nature in the Florida Keys.

A remote island chain 70 miles from Key West, Dry Tortugas National Park is only accessible by boat or seaplane. Its most striking feature is a massive 19th Century fortress surrounded by turquoise waters with vibrant coral reefs, where visitors enjoy snorkeling and fishing. Fort Jefferson is the largest masonry structure in the Western Hemisphere.
