One of the most impressive ways of seeing Chicago is from the water. You can either take part in one of the group architecture tours (which will show you around the city's most impressive buildings) or you can even have a private event organised aboard the yacht called Chicago's First Lady.
$43.53 (plus tax) per person for daytime tours
