Boo at the Zoo

Lions & tigers & bears, oh my!

The Zoo’s annual Halloween extravaganza, Boo at the Zoo, is back for three fun-filled weekends of costumes, festive fall treats, and ghoulish fun.

Gather your ghosts and goblins, put on your favorite costume, bring a bag, and trick-or-treat throughout the Zoo. Be sure to visit all our animal exhibits to see who might be munching on pumpkins or playing with Halloween-themed enrichment! Enjoy seasonal décor, photo opportunities, festive fall offerings, fun children’s activities, and more. Boo at the Zoo is included with your general admission ticket or membership.

Halloween costumes with toy guns and weapons and adult masks are prohibited.
