We sold out of the Architecture River Cruise Groupon very quickly, but Shoreline has offered us another great tour - the Skyline Boat Tour. It's a half hour instead of an hour and you're on the lake instead of the river, but also less expensive: $9 instead of $14. More details below.

Touring Chicago by boat is one of the best ways to see our city. Unfortunately, many locals live here for years without taking a boat tour and learning about Chicago's innovative, important, and gorgeous buildings. Correct that mistake with today's Groupon - Shoreline Sightseeing is offering their Skyline Boat Tour for just $9 - 36% off the normal price of $14. The Skyline Boat Tour departs at regular intervals from the Navy Pier East and West-End Docks. View their schedule here.

Enthusiasts give Shoreline an average of 4.5 stars on Yelp:

• "This tour was really fantastic. It's a really fun way to get to see the city and learn some Chicago history. Our guide, Kip, was super knowledgeable and really funny. There's roof top seating which is key to being able to look up at all the buildings. There's also a full bar on the lower deck." - Katy S.
• "We love it on summer nights - warm with a light breeze, the sun casts a beautiful light on the buildings, and you'll truly feel like you're on vacation in another world. Perfect for the end of a long day in the city." - Amanda G.

Shoreline has been toeing the line since 1939, the year that tourists flocked to the city to see the system of zip cords Al Capone built between skyscrapers to quicken his villains' escapes. It's a family owned and operated business offering the largest touring fleet in all of Chicago. Alcohol, drinks and snacks are available on most tours, and all of their Architecture Cruise boats have easy boarding ramps and are accessible to people with disabilities. You will have six whole months to get out and set sail - but you're land locked until you get your Groupon.
