I gotta say, this is one of the coolest things you can do in Central Florida. We had a great time at Boggy Creek Airboat Rides on Lake Tohopekaliga — part of the headwaters of the Florida Everglades.
We saw endagered birds, a ton of turtles, and — of course — alligators.
If you haven't been on an airboat ride, I would *highly* recommend it. We're definitely going back one day to do the extended sundown tour.
