The following description was submitted by the event organizer.

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 kids learn about healthy habitats for wildlife in a fun scavenger hunt throughout the zoo.

Treat bags are available at the end of the scavenger hunt for an additional fee of $3 per participant. In keeping with the zoo's mission, Howloween aims to be educational as well as fun, and all the treats come from companies that are committed to using deforestation-free palm oil. Learn more about palm oil and how you can help orangutans and elephants with your consumer choices.

Activities are best suited for children ages 2-12, but all are welcome.


What's different this year?

  • Make sure your costumes include masks that cover your nose and mouth.
  • Instead of collecting candy and toys throughout the zoo, Howloween participants may purchase pre-filled treat bags that can be collected at the end of their scavenger hunt. Treat bags are $3 each; tickets for the treat bags will be available for purchase online.
  • All tickets must be purchased in advance, in timed-entry segments. Please note that due to capacity restrictions, even infants need to be counted. Infants are free with a paid adult admission but must have a ticket.
