Gather your ghoulfriends and little ghosts and goblins and head to Brookfield Zoo Chicago for its annual Boo! at the Zoo Halloween celebration. Families will have a fang¬-tastic time enjoying the fall season and the many themed photo frames and vignettes to take memorable snapshots. Take a spin on the Creepy Carousel or the Zoo’s Anniversary Ferris Wheel to view the park in its beautiful fall foliage. Zoogoers can learn about some not-so-scary critters during special zoo chats. Or, watch as some animals receive Halloween enrichment treats—pumpkins. Youngsters can receive their own sweet treat before they leave.
