Mills County, Iowa

Mills County stretches along Iowa’s western border, with the Missouri River separating it from Nebraska. The Loess Hills and Missouri River come together here to create a unique landscape.

Glenwood is the county seat and a small town with a population of around 5,000 people. Mills County is also home to Pony Creek Park, a popular destination for camping, hiking, and birdwatching.

For a glimpse into the past, the Glenwood Archaeological State Preserve showcases the lives of Native American cultures that lived in the area more than 1,000 years ago.
