Visiting Chicago
A Great Lakes city famous for its bold modern and early-skyscraper architecture, deep-dish pizza, and a long lakefront path connecting its parks. It's often cited as the birthplace of the modern skyscraper, and that architectural history is still visible throughout downtown.
Best time to visit: May to June or September to October, avoiding the bitter winter cold and the most humid days of summer.
Landmarks & highlights
- Millennium Park
Home to the reflective 'Cloud Gate' sculpture (locally nicknamed 'The Bean').
- Art Institute of Chicago
One of the oldest and largest art museums in the United States.
- Willis Tower Skydeck
A glass-floored observation deck high above the Loop, with views across four states on a clear day.
- Navy Pier
A lakefront entertainment pier with a Ferris wheel, gardens, and boat tours.
Local tip: A river or lake architecture boat tour is one of the best ways to see the skyline that made Chicago famous for its buildings.
Getting around: The 'L' train network covers downtown and most neighbourhoods well, and the Loop area itself is easily walkable once you're there.
Good to know: Chicago-style deep-dish pizza is closer to a pie than a typical flat pizza — it takes longer to bake, so many restaurants ask you to order it before you sit down.
