Bring your kids to Howloween this weekend for fun, treats and educational activities. 

The zoo provides a fun and safe setting for this Halloween tradition, where costumed trick-or-treaters learn about wildlife in a fun scavenger hunt throughout the zoo.

In keeping with the zoo's mission, Howloween aims to be educational as well as fun. Scavenger hunts and activities are themed to teach kids about animals around the world, and their habitats and adaptations.

Kids can collect treats and prizes at the different stations. Because our everyday actions impact wildlife, the zoo only provides deforestation-free candy. Learn more about palm oil and how you can help orangutans and elephants with your consumer choices.

On the weekend of October 20 and 21, join U.S. Fish and Wildlife Service experts in the Nature Exploration Station to learn about the “Monster Invaders” of the water world (a.k.a. aquatic invasive species) and their impact on our regional wildlife.

On the weekend of October 27 and 28, join U.S. Fish and Wildlife Service and U.S. Forest Service experts in the Nature Exploration Station as we celebrate Bat Week, an annual, international celebration recognizing the important role of bats in our world. 

On all four days there will be Wildlife Live! meet and greets happening at 11 a.m. and 1 p.m. and a bat keeper talk at 3 p.m.

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

Cost: free with zoo admission. Purchase tickets here.

Parking costs $2/hour or $8/day and lots tend to fill up quickly, so the zoo encourages visitors to take public transport: Take MAX Light Rail to the Washington Park stop or a Trimet bus. Call 503-238-RIDE (7433) or visit for fare and route information. Visitors who ride MAX light rail or a TriMet bus to the zoo will receive $1.50 off admission with proof of ridership.
