Sea turtle at Dry Tortugas National Park

Welcome to

Dry Tortugas National Park

Dry Tortugas National Park is one of America’s most isolated treasures — a cluster of islands rising out of the Gulf of Mexico like a mirage. Centered around the massive 19th-century Fort Jefferson, the park blends history, solitude, and marine wonder in a way few places can. Its moat walls and brick bastions stand in stunning contrast to the surrounding coral reefs and shallow blue waters.

Established in 1935, Dry Tortugas protects both the historic fort and the vibrant ecosystem that thrives around it. Visitors come not just for the remote adventure, but for the sense of stepping back in time. With no roads, shops, or hotels, the only way in is by ferry, private boat, or seaplane — and once there, it’s easy to imagine what it must have been like for the soldiers and prisoners who once lived within these walls.

The park’s coral reefs are among the healthiest in the Florida Keys, teeming with angelfish, tarpon, and sea turtles gliding through crystal-clear waters. Snorkelers can explore shipwrecks and colorful coral gardens right off the beach, while campers spend the night beneath one of the clearest night skies in the country.

For those who make the journey, Dry Tortugas offers an experience like no other — wild, remote, and hauntingly beautiful.
