Saint Louis Zoo, is in Forest Park in St. Louis, Missouri. …
It considered one of the best FREE attractions in the USA.
As far as animal prisons go, this one looks very good. Spacious.
Annually, approximately 3 million visitors get the opportunity to experience 16,000+ animals in the Zoo’s care; many of them are rare and endangered. The Zoo is renowned for its innovative approaches to animal management, wildlife conservation, research and education. And as a free zoo, visitors are encouraged to come back again…and again!
The polar bears were a highlight for me.
