The STL zoo is amazing! Although the admission is free, everything about the place is top notch. The staff is friendly and helpful and the grounds are kept very nice. You may need 2 days to explore the zoo as there is so much to see and do. Another nice thing about the zoo is that they allow you to bring in outside drinks and food so you can have a picnic in many of the common areas. This place is a must see on family vacations and is great for all ages.
