About how long does it take to walk threw??

I would plan for 1-3 hours depending on how much time/interest you have at watching the animals. They also have a few kid-activities/play areas and light snacks and beverages in the gift shop. If you were to walk through the park without stopping to look at any of the animals, I anticipate it would take you about 20-minutes.

As long or as short as you would like. I spent several hours there with my 5 year old grandson and definitely could have spent more time there.
