This is a great zoo! I have visited zoos throughout the country and Memphis Zoo is one of my top five favorites. It is beautiful and amazing, I have never seen so many active animals. The display is very large and has lots of natural habitats. A unique feature of the animals exhibited at night, you can see animals in their active turf at night. Bats fly everywhere, great. Hippopotamuses are very active in their large pools and great to watch. The venue is large and beautiful. We walked 6 miles on our tour. There were buses or trams but it didn't run during our tour.
