Chicagoland

Chicagoland covers the suburban ring around Chicago itself — the four counties (DuPage, Kane, Lake, Will) that hold the metro suburbs in a wide arc north, west, and south of Cook. The terrain is flat to gently rolling — Lake Michigan moraine country in Lake County, prairie giving way to the Fox River valley west, post-glacial sand-and-gravel plain to the south. Most of the region developed during the postwar suburbanization wave. DuPage holds Naperville, Wheaton, Downers Grove, and Oak Brook; Kane holds Aurora, Elgin, and Geneva; Lake holds Waukegan, Lake Forest, and Gurnee; Will holds Joliet and Bolingbrook. Anchor attractions include Six Flags Great America in Gurnee, Morton Arboretum in Lisle, Cantigny Park in Wheaton, and Illinois Beach State Park along Lake Michigan in Lake County. Most trips here run as Chicago-extensions rather than standalone destinations. Six Flags pulls the family-amusement crowd; the Morton Arboretum and Cantigny handle garden-and-museum days; Lake Forest and Lake Geneva (just over the Wisconsin line) carry the resort-and-shore weekends; Naperville’s downtown and riverwalk anchor the suburban-restaurant scene. Train access from Metra reaches most major towns.
