The Saginaw Zoo is not huge, but they have done a lot with the space that they have. In the past few years, they have added new exhibits and cleaned the place up a lot. We went there a handful of times and my daughter loved it. Her favorite areas were the monkeys and the penguins. They also have a train ride and a carousel for a little added fun. It is smaller than the Detroit zoo, but much less crowded. It also is only $5 and kids under 2 are free.
