The Yakima Valley Museum's 65,000-square-foot facility offers historical exhibits on the Yakima Valley—its natural history, American Indian culture, pioneer life, early city life, and the roots and development of the Valley's fruit industry. The museum also houses a collection of horse-drawn vehicles, from stagecoach to hearse; an historical exhibit and reconstruction of the Washington, DC, office of former Yakima resident and environmentalist, Supreme Court Justice William O. Douglas; and a changing schedule of special exhibitions. A special set of exhibits, the Children's Underground, provides hands-on activities that complement the core museum exhibitions; and visitors can eat and drink in a functioning replica of a late 1930s Art Deco soda fountain.
The Museum also owns and operates the restored 1898 H.M. Gilbert homeplace, which is available for tours.
The museum offers exhibits, research library access, guided tours for student groups, cultural trunks for rent, performances, and other recreational and educational events.
