Chicago Trolley Company offers guided tours on a fleet of rubber-wheeled "San Francisco-style" trolleys that stop at a number of popular spots around the city, including Navy Pier, the Grant Park museums, the historic Water Tower, and the Sears Tower. You can stay on for the full 2-hour ride, or get on and off at each stop. The trolleys operate year-round, but winter visitors won't need to wear a snowsuit: The vehicles are enclosed and heated during the chilliest months. The same company also operates the Chicago Double Decker Company, which has a fleet of London-style red buses. The two-level buses follow the same route as the trolleys; if you buy an all-day pass, you can hop from bus to trolley at any point.
