Putnam County, Illinois
Putnam County is the smallest county in Illinois, a mere 160 square miles in area. It’s tucked away in the north-central part of the state. Hennepin, the county seat, sits on the Illinois River.
This place is a mix of rolling hills and river bottomlands. It’s mostly rural, with farms scattered across the landscape. The county’s small size and population gives it a tight-knit feel.
The Illinois River, on the west side, provides opportunities for fishing and boating. The nearby Hennepin Canal State Park is popular for hiking and biking. It has a couple of highways winding through making easy access.
