The Alligator Farm in St. Augustine is a small zoo that houses crocodiles, alligators, reptiles, and exotics birds and mammals. I actually went when Gomek, one of the largest crocodilians ever, was alive and had his own exhibit. He has since died but there is a memorial to him titled "Gomek Forever." When I took my kids the last time, they particularly enjoyed the alligator feeding and reptile show, where they had the chance to touch a snake. Good walking shoes recommended and bring some loose change if you want to feed the small crocodilians.
