The Tucson zoo is the perfect size for kids of all ages, and the activities they have are pretty awesome.
There is also the other typical exhibits with a learning building in the middle of them. In this building the kids get to see monkeys up close, draw marine wildlife, and pet a few small domestic animals. There are wonderful stations set up for the kids to sit and reflect on what they are observing.
Also an added bonus we enjoyed were the key stations along the way. When we checked in at the gate, we got a key for two dollars, which we can use over and over at the zoo. Then as we walked the route, there were station boxes where we inserted the key, and a recorded message from a zoo keeper talked about the given animal. It was interesting because the information wasn't just the facts about the species but was personalised to the specific animal we were observing. Well worth the extra bucks. The Reid zoo is also on our Niabi zoo reciprocal list, so we got our whole family in for FREE.
