One of the neatest things I've ever done

Snorkeling around Fort Jefferson and getting the tour was unexpected and awesome. One of the funner days we had in Key West

This is a cool old fort, it's huge. The snorkeling is average, nothing special. I had to keep asking myself, why would you put a fort way out here. Different day, different time, different era. If you get right down to it, this is the last key, not Key West.

This was probably the best family vacation we ever took. We camped for 2 nights, stayed 2 days and although it was the HOTTEST time of the year, it was still amazing. The hermit crabs were everywhere and quite amusing, but at night it sounded like an invading army as they clanked shells walking by our tent. We snorkeled every... More

Fort Jefferson is one of those places you have to make special arrangements to go see. You can get there by sea plane, fast but very expensive, or you can take the daily ferry out there, slow but half the price. We took the daily ferry, Yankee Freedom III. It was a good 2 hour plus ride out. The weather... More

Fort Jefferson in dry tortugas national park is a must do trip. The cheapest way to get there is on the yankee freedom ferry which is a great ride by itself (see accompanying review). Great park full of history and significance. The boat is your home away from home providing the only real bathrooms for the public. Went on an... More

I've had this park on my bucket list for years and years. I took the boat to the island, which is the least expensive way to get to the island. With a 2.5-hour ride each way, you're left with about 2.5-3 hours on the island which I found to not be enough. I went in August and it was crazy... More

My family and I took the Yankee Freedom on the two and half hour trek to the fort. The trip was fabulous. We saw tortoise and dolphin in the wonderfully clear water. On the way, we had breakfast of bagels and cream cheese. Upon arrival, we were taken aback by the sight of the most beautiful, yet strangest, fort. The... More

We camped for two nights on Garden Key in Dry Tortugas National Park. Garden Key is the location of Fort Jefferson, an old unfinished Army fort that was used as a Union prison during and after the Civil War for a short time. It's most famous inmate was Dr. Samuel Mudd who set John Wilkes Booth's broken leg. If you... More

Taking the ferry to the fort was very nice and enjoyable.On our trip we had a nice breakfast and then some of the staff from the Turtle Hospital in Marathon were on hand to give a presentation on the types of turtles found in the keys and the importance of helping distressed turtles and keeping trash out of the ocean.We...

Twenty members of our family took the Yankee Freedom cruise to Fort Jefferson. The boat ride was incredible. Tour included breakfast and lunch. The crew could not have been more accommodating. Upon arrival we opted for the guided tour. So informative!!!Our tour guide Jeffrey was incredible. He dramatized boring, historical facts with wit and humor. The water was beyond gorgeous.... More
