Halloween Decorations & Animal Encounters

Grab a witch’s broom and float around the decorated Zoo where you’ll encounter fun photo opportunities at Candy Corn Lane, the Witchy Walk, Ghost Town, Pirates’ Cove, Fragile Forest Fairyland, Skeleton Picnic, Glowing Jack-o-lantern Tunnel, 10-foot-tall Magic Dragon and Serpents of Historic Hill, and much more.  

Three animal exhibits are open during the event. Slither into the Charles H. Hoessle Herpetarium to catch sight of turtles, tortoises, frogs, toads, lizards, snakes and more. Spiders, centipedes, beetles and other invertebrates await you at the Bayer Insectarium. Meet stingrays and sharks at Stingrays at Caribbean Cove presented by SSM Health.

Activities & Attractions

Eerily draped in cobwebs, the Mary Ann Lee Conservation Carousel transforms into the not-so-spooky “Scare-ou-sel.” Look for strolling entertainers throughout the event.
