Coursing through the heart of the Windy City is the majestic Chicago River, lined with some of the city's finest architecture and dotted with river walks and restaurants. Hop in a boat, kayak, canoe, or gondola and sail down for some of the prettiest views of the city. Some tours even head out to the lake for a skyscraper-studded panorama.
