Lake County, Indiana

Lake County is Indiana’s version of Chicagoland, sitting right along Lake Michigan. Gary was once a booming steel town, but today it’s better known as the hometown of Michael Jackson. You can still visit the Jackson family home.

Hammond and East Chicago give the county its industrial muscle, while communities like Munster and St. John offer swanky suburbs and upscale marinas.

You’ll find surprising pockets of nature here. Indiana Dunes National Park, located to the east, features sandy beaches and rare ecosystems. Meanwhile, Horseshoe Hammond attracts visitors looking to try their luck.
