At the lake, there are airboat and tram tours, plus a restaurant and places to just watch the wildlife.
Here is a not-too-friendly alligator sunning itself on the bank, and a sky full of vultures, plus some on the ground.
There are signs warning you of the vultures damaging cars. Apparently, they like to tear apart windshield wipers and anything else made of black rubber, including the seals around windows. They shoot off fireworks from a gun contraptions into the trees near the campgrounds to prevent them roosting there and munching on RVs.
I took a tram tour and saw deer, raccoons, more alligators, and this turtle. You can see how varied this park is in terms of environment.
