Usually about 2-3 hours. It is partial walk through and a safari ride that is included with your admission. The ride is about 25 minutes long. There is feed for sale in the park for the feeding the animals and lots of different displays of animals to look at. there is a reptile house to look through, plus much more. The walk through area is all flat sidewalks and very easy to get around.
I think about 2 hours sounds right. Possibly even longer if you stop because animals are interacting.
I was there for a little over an hour and saw all exhibits.
I have been there a couple of times & was very impressed. If you want a zoo close to home you will be impressed.
