Iconic Wild Waves Theme Park to Close After 50 Years — Site May Become 1 Million-Sq.-Ft. Warehouse

Wild Waves Theme and Water Park in Federal Way, Washington, has opened for what operators say will be its 50th and final season. The park began its last season on Saturday, May 23, and is scheduled to close permanently on November 1, 2026, after owners cited mounting financial losses.

First opened in 1977, Wild Waves combined amusement-park rides with water-park attractions and grew into a beloved regional destination for families across the Pacific Northwest. Park operators said rising operating costs since reopening after the COVID-19 shutdown generated millions in losses and made continued operation untenable.

Warehouse Proposal and Owner Response

Plans have been filed with the city of Federal Way for a proposed 1 million-square-foot warehouse to occupy the park's roughly 23-acre site, according to reporting by the Federal Way Mirror. Property owner and former park operator Jeff Stock told the Mirror he explored several alternatives — including a hotel and a convention center — before settling on the warehouse plan.

I'm trying to make it good for the city, Stock said, adding he hopes to secure "a great tenant that would provide a lot of jobs."

Stock plans to retain ownership of the land and lease it to development firm Panattoni. Potential warehouse tenants have not yet been disclosed.

Local Backlash

The proposed redevelopment has prompted strong reactions from park fans and residents on social media, many of whom described Wild Waves as a regional treasure. Commenters lamented the loss of one of the area's few family-oriented theme-park options and questioned the wisdom of replacing it with more industrial space, given existing vacant warehouses in the region.

Supporters recalled childhood memories and annual family visits, while others urged local leaders and potential investors to find alternatives that preserve public recreation space.

What Happens Next

Wild Waves will operate through its scheduled closing date of November 1, 2026. In the meantime, city planners will review the warehouse proposal and community members may weigh in during any public-comment periods or hearings related to the development. For now, the park's fate has prompted a broader conversation about land use, jobs, and preserving community amenities.
