Thompson's Mills is a unique survivor of times past, chronicling 160 years of Oregon rural life and honoring the owners who continually adapted the mill to the changing world around it.  It is the last water-powered mill in the state and its turbines can be seen in action on guided tours. A water right that predates statehood produces the water flow that still runs the milling machines for demonstrations today.

The mill and grounds are open from 9:00 to 4:00 daily. Free guided tours are offered whenever we are open- just drop in and we'll show you around. Group tours (10 or more people) are available but please call in advance to ensure adequate staffing. The mill and grounds are every day of the year except Thanksgiving Day, Christmas Day and New Years Day.  There are no fees to visit. The main tour of the mill is accessible by ramps. The mill address is 32655 Boston Mill Drive, Shedd, OR 97377.
