Dry Tortugas National Park

Where History Meets the Sea

Established in 1992, Dry Tortugas National Park protects 64,701 acres of pristine waters and seven small islands. Located 70 miles west of Key West in the Gulf of Mexico, the park is home to the massive Fort Jefferson, one of the largest coastal forts ever built.

The park's clear waters shelter vibrant coral reefs and diverse marine life, while its islands provide crucial nesting grounds for sea turtles and tropical seabirds. The combination of historic architecture, marine ecosystems, and isolation creates a unique national park experience.
