Polk County Museum is at 560 S. Pacific Hwy. W. adjacent to the Polk County Fairgrounds. Chronicling the settlement of Polk County, the museum features exhibits on the main floor that describe the area's Native Americans, pioneers, agriculture, logging, military, towns and cemeteries.
The second floor features famous residents and an early doctor's office, schoolroom, kitchen and parlor, plus period clothing and toys. A kiosk outside the museum describes the Applegate Trail, a southern branch of the Oregon Trail used by wagon-train immigrants from 1846 into the 1860s.
