Boo at the Zoo

Boo at the Zoo brings Halloween festivities to the Milwaukee County Zoo with activities designed to keep things fun without being frightening for young kids. The event features a trick-or-treat trail that runs all day, pumpkin-themed animal enrichment activities, live entertainment, pumpkin-carving demonstrations, and special light shows. Families are welcome to wear costumes, and the Zoo encourages everyone to participate in the seasonal celebration. This year's event expands to include daytime hours on Saturdays, giving families more flexibility to visit. Admission requires a special event ticket purchased online—general Zoo admission and membership passes aren't valid on event days. Zoo Pass Members receive a 15% discount and access to an exclusive members-only activity. Your ticket supports the Zoo's animal care and conservation efforts.
