The Wellington Conservation Center is so slept on.
This place is in a random cornfield in Wellington (it's very easy to miss if you aren't looking for it) and it doesn't get much press, but I think it's an essential visit for anyone in SoFlo.
It costs $25 to a 1-2 hour tour. You get to pet capybaras and goats. Feed lemurs and sloths. They also have cows, goats, turtles and dozens of other exotic animals. The tour guide there is very knowledgeable, and you learn a lot about the animals.
