Explore the St. Louis Zoo after dark at Boo at the Zoo. Bring your little ghouls and goblins to this non-scary celebration designed just for kids. Though this is not a trick-or-treating experience, family friendly costumes are encouraged.
Find various costume characters lurking about the Zoo and play "Hide and Ghost Seek" and look for the ghosts hidden in the trees along Historic Hill. Look hauntingly good as you pose in front of ghosts, pumpkins, Frankenstein or mummies for spooky photos. Take a spin on the not-so-spooky "Scare-ou-sel," the Conservation Carousel draped in cobwebs! Rides are free!
There will also be 10-foot tall Halloween statues lurking around Historic Hill, perfect for spooky selfies. These gentle giants include a skeleton, dragon and snake. Also perfect for pictures is the light-up Saint Louis Zoo sign, which will glow in the dark as night falls.
At the Herpetarium, check out the turtles, tortoises, frogs, toads, snakes, lizards and more! For a little more hocus pocus, check out the Insectarium and see a variety of creepy, crawly creatures. Also be sure to visit the Caribbean Cove! (It's free!)
