This was our favorite single day excursion in our lives, and we've been on a lot of them. I'm ready to get a job as a Park Ranger at Ft Jefferson, it is that cool a place. Great history, awesome snorkeling, and paradise on earth - like the prettiest tropical island you can imagine. LOVED it! Check out my pics. I will say that the one downside for some is the boat ride out. It can be a little rough at times, so take Dramamine accordingly if you need it. I'm a Senior Chief in the Navy, so of course I enjoyed the rockin' n' rollin', but a few of our fellow passengers got a little queesy. When you get to the Dry Tortugas, be sure to take in Ft Jefferson first, and learn about Samuel Mudd and the Lincoln conspirators, and then snorkle up at the north coaling pier ruins. The pilings are covered with coral, and you'll see everything from Angelfish to Barracuda swimming around. Totally awesome experience for the whole family, and if you are DOD, be sure to visit the ITT office at Sigsbee Annex to get your discounted tickets. Thanks again for a great day, Yankee Freedom staff! We'll definitely be back.
