Chicago’s regular, grid-like layout makes navigation straightforward, but the “City With Big Shoulders” can be a little too large to get around easily on foot. Fortunately, the city’s public transportation system, including the famous “L” (short for “elevated train tracks”), is efficient, with especially good coverage in the city centre area. Traffic is often congested, especially during rush hour, and driving isn’t recommended. Cycling is a popular way to get around and with all of Chicago’s lakefront property, it can be a great way to enjoy the city.
Chicago’s major airport is O’Hare International Airport (ORD) located in the city’s northwest corner, about 27 km away from the Loop. The Blue Line of the Chicago subway (known as the ‘L’ to locals) connects O’Hare directly to the city, and commuter rail services are easily accessible by a short shuttle ride. Taxi and car hire services are also available.
One of the biggest challenges for visitors to Chicago can be the weather. Fiercely hot in the summer, the city is bitterly cold and windy in the winter. In the winter, wear layers and don’t expose skin to the wind; in summer, be sure to drink plenty of water.
