I can highly recommend the architecture tour an the Chicago River. A lovely way to get to know the city and its marvellous architecture better. Staff on board is very professional and the guide really knew a lot about the buildings. She was also open to extra questions.
Boats come equipped with toilets and a café, if you like some beverages during your trip. The inside of the boat has air conditioning, but we preferred sitting outside to have the best views.
It doesn’t matter if you take this boat ride during the day or during the night. You will definitely enjoy it.
