About Chicago

Though it's only the third largest city in the U.S., Chicago is nothing short of a world hub. There are so many things to do, most people find one visit isn't enough. The city delivers architecture, art, shopping, nature, and one giant dinosaur.

When to Visit Chicago

Chicago is a big, bustling city that's popular all year long. Deciding when to visit, and when to book, will determine how much you spend on accommodations and airfare.

Before you begin to plan, take into account Chicago's seasonality, weather, crowds, and hotel options. Then decide when to go based on what you want to do in the city and on your budget.

Chicago is popular throughout the year, mostly due to conventions. June and September are particularly difficult months to find inexpensive accommodations. However, if you're willing to brave cold gusts from Lake Michigan, January, February, and March are less busy than the rest of the year. During winter, you might be able to take advantage of promotions from hotels and low-season airfare.

Like most cities in the U.S., Chicago is particularly popular in the summer vacation months, especially during events such as the Taste of Chicago, and over the December holidays. Leisure travel, coupled with business and convention travel, make the popular tourist areas—the Loop and Near North—book up quickly. You can also expect mid-morning and afternoon crowds at popular attractions and museums, particularly on free days.
