Located almost 70 miles west of Key West, Dry Tortugas National Park preserves a cluster of seven islands, called the Dry Tortugas, and their surrounding shoals and water. One of the park’s main attractions is Fort Jefferson, a coastal fortress built from 1846-1875. While construction of Fort Jefferson was never finished, it is considered the largest masonry structure in the Western Hemisphere with over 16 million bricks.
Visitors to Dry Tortugas National Park can explore Fort Jefferson, enjoy world class bird watching, relax and camp on the beach, and snorkel the surrounding waters filled with abundant sea life and pristine coral reefs. As one of the most remote parks in the National Park System, Dry Tortugas National Park is accessible only by ferry, seaplane, private boat or charter boat.
