About Dry Tortugas National Park
Dry Tortugas National Park protects seven small islands and their surrounding waters, 70 miles west of Key West in the Gulf of Mexico. The park is dominated by Fort Jefferson, one of the largest masonry structures in the Americas, built in the 19th century to control shipping lanes. The surrounding waters offer some of the clearest in North America, with pristine coral reefs and abundant marine life. The remote location means no light pollution, making it one of the best stargazing spots in the eastern US.
