I saw some things at this zoo I'd never seen before: An anteater eating his breakfast (a dish of what looked like meal worms)...dwarf mongooses up close...spiny anteaters...and two cassowarys. Employees were very friendly, helpful and eager to answer any questions. This is by far the best zoo I've been to in terms of friendly zookeepers, concession workers, volunteers and staff.
Be sure to buy tickets to feed the giraffes (unmarked ticket concession near the giraffe exhibit...ask ahead of time where to go to buy tickets; they're only available at 10 a.m., 1 p.m. and 4 p.m.). It's marvelous to see a giraffe up close! Don't miss that experience!
The reason I didn't give a 5-star review is the map and signage are poor. (That's why I know the employees and volunteers are helpful -- I kept asking for directions!) Animals are not always clearly identified with signs on the exhibit...sometimes there are a group of pictures of animals you might see in the next few exhibits but sometimes you see animals that aren't pictured and there's no information about them.
There are surprisingly few water fountains, but when I asked for water to refill by water bottle at a concession stand, there was no problem. It was filled gladly, and for free, with cold filtered water.
Today, a standard admission adult ticket cost $17.50 so the price advertised on Trip Advisor is a good deal. I wish I had bought that voucher!
