Saline County, Illinois

Saline County is in southeastern Illinois, not far from the Kentucky border. Harrisburg serves as the county seat and is the biggest town in the area. These days, agriculture is the main driver of the local economy.

The Shawnee National Forest extends into the southern part of the county, making it a favorite with hikers and campers. Glen O. Jones Lake is also popular for fishing, boating, and, of course, relaxing.

Harrisburg has a pleasant downtown with several local shops. But like many small Illinois towns, it’s facing some economic challenges. Saline County isn’t flashy, but it’s a place where family roots run deep and traditions still matter.
