Chicago

The Chicago region centers on Cook County and the city of Chicago itself, the dominant urban anchor of Illinois and the third-largest city in the United States. The setting is Lake Michigan’s southwestern corner — a flat lakefront plain with the Chicago River cutting through the downtown core — and the city extends roughly 25 miles north to south along the lake. Cook County holds Chicago proper and the inner suburbs. The downtown Loop, lakefront museums, and the neighborhoods (Lincoln Park, Wicker Park, Hyde Park, Logan Square, Pilsen) carry most of the visitor weight. Major anchors include the Art Institute, the Field Museum, the Shedd Aquarium, Millennium Park, Navy Pier, Wrigley Field, and the lakefront trail running 18 miles along the water. Most visits build around two or three concentrated days. The Loop and Magnificent Mile handle the architecture and shopping; the museums cluster on the Museum Campus south of downtown; the neighborhoods reward longer stays. Public transit reaches almost everywhere visitors want to go. Summer is festival season; winter is brutal but compresses the indoor itinerary into something manageable.
