This cool, clammy environment is created by air currents, waterfalls and specialized visual experiences. Each area of St. Louis Children’s Aquarium is designed to create ambiance based upon all senses being engaged. After visiting the Wild Cave Adventure Room, cave explorers must orient themselves back to the rest of the museum. In this room, children and adults can experience the sport of spelunking (cave exploring) in a fun and exciting way by crawling through man-made replica of a cave complete with a stalactite dripping water and a hidden staircase located behind a tree. See some of Missouri’s most common terrapins and snake den.
