Chicago has one of the largest public transportation systems in the country and getting around the city is fast and easy with an extensive network of train and bus routes. The train system is known as the "L"; most visitors only use the "L", but buses also cover every part of the city including the suburbs, albeit less regularly. Most trains run 24 hours a day, with Overnight or Night Owl services taking over between midnight and 5am on some lines.
The Metra commuter trains link the city to the outer suburbs, including Lake Michigan, Hyde Park, and McCormick Place. During the summer months, a free trolley system operates in the downtown area, connecting Chicago's top cultural attractions, shopping areas, and visitor destinations. Taxis are easy to find, and the metered rates are reasonable for short journeys. Although traffic is not as bad as in other major cities (outside rush hour), parking is expensive and difficult to find.
