1,200 animals on exhibit at our Zoo, including our collections of mammals, fish, invertebrates, birds, and reptiles. It approximately has 2.5 miles of walking trails. The Zoo has been divided into four different trails; usually the Africa and Tropics Trails take about an hour each and the Arizona and Children’s Trails take about a half hour each. We recommend approximately 2 and a half to 3 hours to see the Zoo, depending on the size and ages of your group, and how fast you walk.  Because we create exhibits that replicate the natural habitats of our collection, some animals can be difficult to see and visitors may be required to spend more time in observation.
