Bring your costumed kids to Howloween for treats and safe fun! 

The zoo provides a fun and safe setting for this Halloween tradition, where costumed trick-or-treaters learn about healthy habitats for wildlife with engaging activities throughout the zoo.

Activities are best suited for children ages 2-10, but all are welcome.
