See Chicago by night and learn about its rich architectural history on a 75-minute evening sightseeing cruise along the Chicago River. Explore three branches of the famous waterway while ogling the city’s skyline and landmarks, all impressively illuminated by night. Sights of roughly 40 iconic buildings are included such as Willis Tower (Sears Tower) and the John Hancock Center, and the onboard guide — an architectural expert — will explain their history throughout the cruise.
