My grandfather is 85 years old and want to come. Is there any handicap or elderly way of getting around the zoo or would we have to push him in his wheelchair.

Except for the alligator at the bottom of the hill, you can walk to everything else without struggle. All walkways are paved or boardwalked. A wheelchair wouldn't be a problem. Fences and railing around each animal could be used for balance. He will be able to feed the animals standing or seated.

You would need to have him in a chair. There is a short Hill at one point.
