About Hillsboro

Hillsboro is a welcoming small town and the county seat of Montgomery County, set among the rolling hills of south-central Illinois. Home to roughly 5,800 residents, the city sits about 50 miles south of Springfield and an hour northeast of St. Louis. Water recreation is a big part of the local lifestyle, with Lake Glenn Shoals and Hillsboro Lake bordering town to provide plenty of fishing, boating, and lakeside parks. The historic downtown centers around the Montgomery County Courthouse, featuring local eateries, shops, and restored storefronts.

Families moving to the area are served by Hillsboro Community Unit School District 3. Day-to-day life is relaxed and manageable, with most neighborhood spots and community parks just a few minutes apart. For major retail chains, medical centers, or commuting, residents can easily make the short drive west to Litchfield or take day trips into Springfield and the St. Louis metropolitan area. It is a quiet, friendly place to settle down while keeping larger city amenities within easy reach.
