Johnson County, Iowa
Johnson County is located in east-central Iowa, where cornfields meet college-town vibes. Iowa City, home to the University of Iowa, keeps the county’s 155,000 residents on their toes.
The Iowa River flows through the county, eventually forming Lake McBride and Coralville Lake. Interstate 80 and U.S. Highway 218 make the area a key location, providing easy connections to the rest of the state.
The Iowa Writers’ Workshop has produced more than its fair share of literary legends. But the county isn’t all books and boats. Venture outside the city limits, and you’ll find plenty of farms.
