Hamilton County, Ohio

Cincinnati’s the big show in Hamilton County. It’s right in the southwest corner of Ohio, hugging the Ohio River. It borders both Indiana and Kentucky. This place is hopping with over 800,000 people call it home.
The Reds and Bengals keep sports fans happy year-round. You can’t miss the impressive skyline when you’re driving in on I-75. Visitors love the food here too. From chili to goetta, there’s always something tasty to try.
The county’s not just about the city though. There are some great parks for when you need a breather. Visitors dig the Underground Railroad sites. And if you’re into art, the Cincinnati Art Museum is a must-see.
