About the Event

It’s no trick, only the sweetest treat: Boo at the Zoo, Smithsonian’s National Zoo and Conservation Biology Institute’s beloved family-friendly Halloween event, sponsored by Mars Wrigley Confectionery, is back Oct. 20, 21 and 22 from 6 p.m. to 8:30 p.m. 

Guests can feast their eyes on spellbinding habitats decorated with Jack-O-Lanterns, spooky enrichment and tasty treats for the animals. Fiendishly fun vignettes featuring frolicking skeletons and fantastical creatures liven up the Zoo’s main pathway, Olmsted Walk.

Tickets include special after-hours access for animal viewing at the Elephant Community Center, Small Mammal House, Reptile Discovery Center, a souvenir tote bag and around 30 trick-or-treat stations around the Zoo.
