This video starts with the take off on a seaplane in Key West and a water landing in the Dry Tortugas at Ft Jefferson. The fort is accessible by boat or plane.
I visited Ft Jefferson for 3 days on a marine expedition doing soil samples of the sea floor in college. It was fantastic.
I also took a 3 day fishing vacation to the Dry Tortugas for a friends birthday. It was a lot of fun. Just outside of the park I caught and released a 500 pound jewfish. That fish nearly broke my back. My friends caught and released some beautiful tarpon.
Don't miss the Dry Tortugas and Ft Jefferson!
