Starting from the bustling heart of downtown Chicago at 400 N Michigan Avenue, the Chicago Lake and River Architecture Tour offers a 90-minute voyage through more than two centuries of architectural achievement and city history. Boarding a classic vessel staffed by knowledgeable guides, travelers glide onto the Chicago River where towering steel and shimmering glass reflect the city’s industrial grit and artistic ambitions. The river, once tamed through a groundbreaking reversal project in 1900, now dares visitors to see its banks as an open-air museum where each building tells a story.
