This is one of the best zoos in the world. The only two zoos I have seen that were more impressive were San Diego and Singapore but we are lucky to have this in our back yard.
The animals are well treated and have dynamic living environments, the staff and exhibits so a great job adding education to the experience. I love walking around in a tropical environment in the middle of winter. When the kids were young, this was a particular blessing and we went all the time. Each of the geographically themed areas is easy and engaging to walk through. They also have a waterpark that is well done and the kids enjoyed when they were young.
It is expensive but exceptional and serves an important function to promote conservation and understanding. I am always happy to pay the fee.
