Eco-tourism done right! You get to see (mostly) wild animals in their natural habitat going about their business: raccoons (partially domesticated through feeding by tour guides), wild piiiiiiigs!!! (if they show up), laid back alligators of all sizes, and a number of beautiful bird species. We went early December (in unusually warm low 70s) and the gators were still active.
If you get a chance to hold a baby alligator after the tour, go for it!
