Every year, the Great Plains Zoo thrills children and adults alike with our Halloween extravaganza! ZooBoo promises to be a spooktacular evening, with more treats, more fun, and more surprises than ever! Hand-carved Jack-o-Lanterns illuminate the night pathways as you stroll through Zoo grounds gathering treats along the way! Visit the ever-popular Carved Pumpkin Display and various Treat Tents, plus find new tricks and treats throughout the Zoo. ZooBoo is held rain, snow or shine and is completely outdoors – so be sure to dress for the weather.
