Festive Fun and Activities
Take a break from the Halloween action at the kids’ game area behind Stingrays at Caribbean Cove presented by SSM Health.
Find educational activity stations around the Zoo and learn about some of the Zoo’s creepier animals!
Look hauntingly good as you stick your face into bodies of a ghost, pumpkin, Frankenstein or mummy for spooky photos.
Take a spin on the not-so-spooky "Scare-ou-sel,” the Conservation Carousel is draped in cobwebs! Also, be sure to visit the Haunted 4D Theater for a showing of "Happy Family 4D." (Free with Boo at the Zoo admission.)
One, two, three…say cheese! There are 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 our light-up Saint Louis Zoo sign, which will glow in the dark as night falls.
Get lost in a world of orange at our pumpkin maze, located at the south entrance.
Here’s a spooky good deal—Stingrays at Caribbean Cove is only $2 per person (normally $3.95 per person).
At the Charles H. Hoessle Herpetarium, check out the turtles, tortoises, frogs, toads, snakes, lizards and more!
For a little more hocus pocus, check out the Emerson Children’s Zoo and see some a variety of animals, from fennec foxes to Tasmanian devils.
Catch a glimpse of sea lions and harbor seals taking a nighttime swim as you walk through the Holekamp Aqua Tunnel, located at the Judy and Jerry Kent Family Sea Lion Sound.
Please note, these are the only animal exhibits open at night during the event.
Get pumped for some spooktacular nightly entertainment acts! Shows are offered at 6:30 and 7:30 p.m. inside the Sea Lion Sound arena and are FREE with paid admission to Boo at the Zoo.
Tickets will be handed out on a first-come, first-served basis outside the Sea Lion Sound ticket booth, so be sure to stop by early!

- Scary costumes are not permitted
- Facial features on guests age 13 and older must be recognizable (no masks, no face paint that completely conceals the face)
- Costume appropriateness is up to the discretion of Zoo security
- See full costume policy here
