I arrived about a half hour after it opened and 1/3 of the animals were not even out as they were still cleaning cages and feeding the animals and 1/3 of the zoo is under construction.
I paid just under $20 for that! That's ridiculous!
The zip lining course looked interesting (extra cost ??) and there is a little water park area and petting zoo.
