10. St. Louis Zoo

Great FREE zoo!
Free zoo! So much to see but hard to do in one visit. Some of the attractions cost but some free highlights: watch feeding of Seals; check out the Bear pits; walk through Primate house with Gorilla enclosure; see Elephants in outdoor enclosure; and many, many more animals. The Zoo train (costs) is a nice relief for tired feet! Parking on the lot is $11 but free parking is available in Forest Park if you walk a little. St Louis Zoo is top rated and you will know that after your visit.
