About Rio

Located about fifteen minutes north of Galesburg in Knox County, Rio is a quiet farming village with a strong community feel. If you are moving here, the first thing to know is the pronunciation: locals say "RYE-oh." The town is surrounded by open Illinois farmland and the gentle timberlines along Henderson Creek, making it a peaceful spot to settle down. Local kids attend the ROWVA school district alongside students from neighboring Oneida and Altona. It is an ideal setting for anyone looking for affordable, low-key country living within an easy drive of bigger-town shopping, healthcare, and dining in Galesburg.
