We did river cruise, Downtown Deco & Modern Skyscraper tours. Latter was a bit dull in places, but first 2 were terrific. We saw buildings (inside and out) that were not mentioned in guide books, and the guides gave us tips on seeing things (like the inside of the Trump tower) that we'd never otherwise have known about.

CAF boat tour was one of the top highlights on our trip to Chicago. The tour guide was very knowledgeable, yet explained things in ordinary terms, using lots of analogies so us non-engineers/non-architects could understand! I've visited Chicago two times before, but this was the first time I'd been on this tour, and I'm so glad I finally made it. You get to see a totally different side of the city via boat then you do by foot.

This tour was great - but too short.

There are so many fantastic buildings that the docent (guide) hardly had time to breathe during the 90 minute tour. The views of the buildings and the history and facts behind them were amazing and I wouldn't have missed it for anything.

I do think that a 2 hour tour would provide a bit of reflection and photo time and would be more enjoyable because of it.

I've done the boat tour twice and it's the best attraction in Chicago. Knowledable guides and a great trip along the Chicago river and it's forks. Can be busy on a sunny summer weekend so you'll need to book ahead.
