Galena, IL to Stillwater, MN: Ultimate Road Trip Guide

The route from Galena, Illinois, to Stillwater, Minnesota, traces the southwestern edge of the Driftless Area—a region that escaped glacial flattening, leaving steep hills, deep river valleys, and limestone bluffs. This 200-mile drive, primarily along US-20, US-52, and I-94, typically takes 4.5 hours without stops. The most surprising detail? The Galena River, flowing through Galena, is actually a tributary of the Mississippi, and the road north parallels the great river for much of the journey, offering multiple panoramic views of the Mississippi Valley.

Toll roads are absent; all segments are free. Average fuel economy: around 25 mpg; plan for one fill-up. Gas stations are frequent along US-35 and near interstate exits.
