Speeding out across the Everglades in an airboat is fantastic. Although it can seem scary at the beginning, when you actually see the alligators in their natural habitat, then it's all worthwhile.
When you finish the ride, there is a small cafe on site where you can get some lovely meals at great prices. The one thing I would say is that they do have alligator on the menu (which is not very nice when you have just been to see the live ones).
