Mill Towns State Trail is a work in progress with three segments that are currently unconnected, totaling six miles. The trail segments all run parallel to the Cannon River and connect into the cities of Northfield, Dundas, and Cannon Falls. It will ultimately serve as a 25-mile connection between two other long-distance trails: Sakatah Singing Hills State Trail and Cannon Valley Trail.
The trail name comes from the many mills that were constructed on the Cannon River by white settlers in the late 19th century. The vision is for the trail to interpret the history of the flour milling industry that sprung up and fostered the growth of several cities in the region, which led to Minnesota being a major milling state in the early 20th century.
