Peak Season:

Winter is a prime time for skiing and snowmobiling in Illinois. Summer is the peak of the festival season in the Chicago area with major events taking place in the parks and neighbourhoods every weekend, despite the heat and humidity. While many tourists gather on the great state of Illinois during the summer season, it’s more likely cheap flights to Illinois will be available during the winter months.

Off Season:

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.
