This is one of the nicest zoos I've been to. They make great use of natural terrain and artificial boundaries to make it look a lot bigger than it really is.
I grew up in the Cincinnati area and have been going to the zoo for about 50 years now...it's changed quite a bit in that time, but it has some great exhibits and really good programs for education and breeding endangered animals.
My family are members and we go about once a month. We like to take our time, pick out a handful of animals to see each trip, and spend some time watching them, their behavior, and talking with the kids about why they may act certain ways or have different colors.
The zoo has handlers that go around to different buildings or areas of the zoo and show small animals to the guests and answer questions about them. My daughter likes seeing all the different kinds of snakes and comparing how ones that live in a desert may have scales that feel different from ones that live near water.
