Slug Fest reigns supreme as one of the zaniest weekends of the year at Northwest Trek. Celebrate all that is slimy and silly about the Pacific Northwest’s most valuable and misunderstood mollusk: the yellow-greenish banana slug.

Banana slugs are fascinating decomposers that break down organic matter and return nutrients to the soil. Without decomposers, forest floors would quickly become overrun with plant and animal waste, rather than being a beautiful place for regrowth.

To celebrate banana slugs, trams will be equipped with tentacles as they make their way through the wildlife park’s 435-acre Free-Roaming Area on an animal-watching Discovery Tram Tour.

Make slug crafts and tentacles to take home. See animals up close during special Animal Encounters at 11:30 am and 1:30 pm. And get ready to slip and slime down a soapy track to victory during human slug races! All FREE with admission. For lodging near Northwest Trek Wildlife Park click here.
