Enjoy the beautiful scenery of Northeast Iowa by bike. Just outside Dubuque is the small town of Sageville. It is here that a bike lane begins traveling along the Great River Road. The path runs from Sageville through the small towns of Sherrill and Balltown, to the Dubuque County Line. In total the bike path runs approximately 13 miles. Along that route you will experience small town Iowa, rolling hills of farm land, and views of the Mississippi River.
