Chicago has an inexpensive and reliable public transportation system, the Chicago Transit Authority (CTA). For just a few dollars, you can take the CTA train from the airport to Columbia. Once you are downtown, this is also a good way to see the city as much of the train system is above ground. Taxis are another good way to get around. A trip from the airport runs about $40, and trips around town will run somewhere between $5-$10. Car rental is not recommended as it is expensive and generally turns out to be more hassle than it is worth. Uber and Lyft are also excellent choices for getting around town. There are also a number of Divvy bike sharing stations throughout the downtown area if you prefer to get around by bicycle, and it's only $10 a day to rent a bike. The best plan is to bring a comfortable pair of walking shoes as everything is within walking distance from Columbia's campus.
