Peoria to Alton: Scenic Illinois River Road Trip Guide

Peoria and Alton sit along the Illinois River, connected by a scenic two-hour drive on Illinois Route 29 and the Great River Road. This route shadows the river’s bends, offering a journey through river towns, bluffs, and farmland. A lesser-known fact: the section near Meredosia follows an ancient Native American trail that later became a stagecoach route.

The distance is roughly 100 miles, with clear highways and few traffic lights. It’s a drive that rewards those who take their time, with numerous pull-offs and parks. For more on crafting your own road trip, see how to find the best stops and hidden gems between cities.
