Boo at the Zoo (a walking event this year) will feature wicked family-friendly activities including a Trick-or-Treat Trail, live pumpkin-carving demos, dazzling light shows, plus so much more! Several of the animal buildings will be open just for this event!

Enjoy these fun not frightful activities:

  • Trick or treat through “Adventure Africa” with 10 different sweet spots. Costumes are encouraged and all candy is made with sustainable palm oil. (Trick-or-treat bags are not provided.)
  • Be dazzled by a light show and Halloween décor throughout the Zoo including Pirates Cove, the Candy Corn Farmer’s Market, and Spooky Hollow.
  • Go Batty for Mad Science Milwaukee! Kids will surely enjoy some spooky science at these fun stations: Monster Design Lab, Dr. Van De Graaff’s Hair Salon, and Mad Scientist’s Laboratory.
  • Ride the not-too-spooky North Shore Bank Safari Train turned Halloween-themed ride – a delight at night!
  • Learn all about our animals! The Creature of the Night talks will be complete with Halloween-themed conservation connections.
  • A variety of food and beverages will be available throughout the Zoo.
