Porter County, Indiana

Porter County is located in northwest Indiana, along the shores of Lake Michigan. The Indiana Dunes National Park is the county’s jewel. People love to climb the massive sand dunes.
The county also features a mix of small towns, like Valparaiso, which is home to Valparaiso University and a lively downtown area. But head north to Portage or Chesterton, and you’re in pure suburbia.
It’s a place of stark contrasts, where steel mills share the lakefront with pristine beaches. Porter County’s not all lakefront though. Most of the southern part is pure Indiana farmland.
