It’ll be all treats and no tricks for your little pirates and princesses at this year’s Boo at the Zoo, the region’s most unique Halloween event. Boo at the Zoo is a fun way for families with young children to trick-or-treat and enjoy Halloween festivities, and all of our candy is made with sustainable palm oil to help protect wild orangutans. Support the Zoo’s efforts to reduce waste by bringing your own trick-or-treat bag from home. COVID-19 precautions will be in place.
