How long does a visit last?

As long as you want. I didn't have anyone telling me I had certain time. And there's a lot of different animals so you can take your time.

It really depends on your level of interest in the animals, you could power walk the whole thing in less then five minutes but it is very dense in displays several layers so if you spent about a minute at each you could be there for a couple hours.

My son stayed more than 2 hrs but for me maybe 30 min..haha

A regular zoo visit can last a long time but they have vip visits too that are more up close and personal that have a time limit

I was there for a good hour
