We rented motorized scooters and explored the entire zoo. Had lunch in the cafe. Took about 4 hours. We used the free map handed out at the entrance. Another time went with the kids in the summer heat. Just hit the main points of interest. Took about 2.5 hours.
If you go slow and look look at everything maybe 2+ hrs if you go fast maybe an hr
We rode the tram first and then went back to through the areas. 4 hours included the tram and 4D movie Animals. We didn't go through the petting animals area.
Casually walking, I've been there for 1.5 hours and I didn't even see all of the animals.
