The river boat tours were really wonderful and relaxing, so much so that a high percentage of us took them more than once!  We saw lots of alligators, turtles, Common Moorhens, Anhingas, Wood  ducks, Great blue herons, Yellow crested night herons and a couple of snakes sunning themselves on branches, and some deer.  A couple of the Tarzan movies were filmed here, also Creature from the Black Lagoon.
