Jasper County, Iowa

Jasper County is where city life meets the country. Newton serves as the county seat and was once known as the “Washing Machine Capital of the World.” How’s that for a claim to fame?

These days, the county is better known for its connection to NASCAR and the Iowa Speedway. With a population of around 38,000, Jasper County has plenty of activity to keep things lively.

Mariposa Recreation Area offers a peaceful break from the hustle and bustle, while the Neal Smith National Wildlife Refuge gives visitors a glimpse of what Iowa looked like before all those cornfields took over.
