Dry Tortugas starts in Key West, but it is not a quick drive

Dry Tortugas is close to Key West on the map, but it is not a bridge drive.

The park sits almost 70 miles west of Key West. It is mostly open water with seven small islands. Visitors get there by boat or seaplane. Fort Jefferson is the big historic anchor, but the first rule is practical: this is a remote national park with limited services.

The distance is part of the magic. You leave the busy edge of Key West and head toward clear water, birds, reefs, and one of the most unusual fort settings in Florida.

The distance also changes the day. Weather can matter. Seats can sell out. Food, water, shade, and time all need a plan before you leave the dock. This is the kind of trip where a little homework makes the fun easier.

Book transportation, check weather, and read current park alerts before you count on the trip. For someone living in Key West, Dry Tortugas is local color with a planning list attached.
