Iowa County, Iowa

Right in the heart of eastern Iowa, Iowa County shares its name with the state. It’s a place where small towns and rolling farmland come together, offering a snapshot of classic heartland life.

The Amana Colonies, a group of seven historic German villages, are the county’s claim to fame. Visiting these villages feels like stepping into a time machine, with handcrafted goods and family-style restaurants adding to the old-world atmosphere.

Marengo, the county seat, keeps things running smoothly. The Iowa River flows through the area, offering opportunities for camping, fishing, and enjoying some fresh air. And let’s not forget the outlet mall in northern Williamsburg, because even pioneers need a good deal now and then.
