Boo at the Zoo 2025: A Family Halloween Adventure

The Milwaukee County Zoo is transforming into a not-so-spooky wonderland this October with Boo at the Zoo, presented by Prairie Farms Dairy. Back by popular demand and expanded for 2025, families can now enjoy two weekends of Halloween fun: October 17–19 and October 24–26, from 5:30 p.m. to 9:00 p.m. each night.
