We welcome all visitors to get into the Halloween spirit and dress up for this event. However, the Zoo is a family-friendly place, and we have policies in place so little ones don't go "boo-hoo" at Boo at the Zoo:

  • 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
