Why it's so great: For starters, you have to take a boat or seaplane to get there. Located 70 miles off Key West, the Dry Tortugas were first discovered by Ponce de Leon back in the 1500s ("tortuga" means turtle, and Leon found a shitload there). Today the national park gives you both history (Fort Jefferson once housed Samuel Mudd, the doctor who treated Abraham Lincoln's assassin) and vitamin sea aplenty. Never mind that the beaches are dotted with abandoned vessels from asylum-seeking Cubans.
Must-do: The snorkeling here is epic, owing to the fort walls that lend shelter to all sorts of fish -- including, yep, barracuda
