BOO! at the Zoo

Join us in October 2026!

BOO! at the Zoo is Knoxville’s largest Halloween event featuring several nights of not-too-scary Halloween fun perfect for preschool and elementary-aged children. A Halloween tradition, BOO! at the Zoo is a family event featuring trick-or-treating along the BOO! Trail, where little trick-or-treaters can fill their bag with goodies as they make their way through the zoo. Wander through our haunted cemetery and enjoy spooky snacks—it’s a fang-tastic time! BOO! At the Zoo is proudly Sponsored by Chick-fil-A Knoxville.
