Getting around Illinois

A tough city to drive in, Chicago has convenient public transportation, taxis are easy to come by, and many areas are a pleasure to walk through. The Chicago Transit Authority operates the “L” (or “El”) a system of elevated trains that run 24 hours a day. There is also a River Bus that runs during rush hour in the summer, and the city is becoming increasingly bike friendly.

Except for Chicago, Illinois is mostly a quiet, rural state. Yet Amtrak trains, numerous commuter railroads, and, to a lesser extent, buses make getting around on public transportation feasible. Cycling is also generally easy on the state’s flat plains.

Once you reach your destination, check for local transportation, but be prepared to rent a car.
