Overview
Dry Tortugas delivers what most national parks can't: crystal-clear snorkeling among vibrant coral reefs, a massive 19th-century fort you can explore room by room, and some of the darkest skies in Florida. The catch? Getting here costs $200-$400 roundtrip via ferry or seaplane from Key West, and there's no food service once you arrive. With only 85,000 annual visitors spread across 100 square miles of mostly water, you'll have the snorkel trails nearly to yourself—if you can afford the boat ride.
Book the Yankee Freedom ferry's first departure (8am) and stay until the last pickup (5:15pm) to maximize your nine hours on the island. Bring twice as much water as you think you need—the sun reflecting off white sand and fort walls is brutal, and the only shade is inside Fort Jefferson's narrow corridors.
