We were there for several hrs, along with the wonderful train ride we had a good time, except for the heat, next time we will go in early spring.
It's a 50 acre zoo. And yes depends on how long you stay to pet, feed, and look at all the animals, not to metion the train. Me my kids and husband was there for 3-4 hours.
If you're walking and overhung, feeding the animals, etc., about 2 hours!
I really depends on if you stop to feed some of the animals or go into the bird sanctuary.
