A division of the Missouri Botanical Garden, this favorite attraction draws visitors year round. The highlight of your visit will be the Butterfly Conservatory, where visitors can witness the spectacular sight of thousands of exotic butterflies in free flight amid an exquisite flower garden. The outdoor Native Butterfly Habitat and Teaching Gardens feature butterflies and plants native to the state. Enjoy the sculpture gardens, where kids can explore a thirty-foot long "Lopatapillar."

More than 6,000 animals live in natural habitat areas constructed to resemble bluffs, pampas, lakes, and woods. Visit the Children's Zoo, New River's Edge and Insectarium, the Jungle of the Apes, and Big Cat Country, with lions, tigers, jaguars and leopards. Ride the Zooline Railroad around the park's beautifully landscaped grounds.
