Top Things to Do
Architectural River Cruise at Sunset
Glide along the Chicago River as the sun dips below the skyscrapers, casting a warm glow on the city's legendary architecture. A knowledgeable guide will point out the historical significance and unique design elements of each building, offering a perspective you won't get from street level. Consider a later evening cruise in summer for a different, illuminated cityscape.
Picnic and People-Watching in Lincoln Park
Escape the urban bustle with a leisurely picnic in Lincoln Park, a sprawling green oasis. Beyond the zoo (which is free!), discover hidden gardens, charming statues, and stunning lakefront views. Find a quiet spot near the South Pond for a picturesque backdrop, or join the locals for a game of frisbee on the main lawn.
Deep-Dish Pizza Pilgrimage to Pequod's
Venture beyond the tourist traps for a truly authentic Chicago deep-dish experience at Pequod's. Their caramelized crust, a crispy, cheesy ring around the edge, is legendary and a must-try for any pizza aficionado. Arrive early or be prepared for a wait, especially on weekend evenings.
Art Institute's Impressionist Wing Before the Crowds
Immerse yourself in the masterpieces of Monet, Renoir, and Degas in the Art Institute's renowned Impressionist collection. Aim for a weekday morning, ideally right at opening, to have these iconic works almost to yourself. The subtle play of light and color is best appreciated in quiet contemplation.
💡 Travel Tip: For the best value on hotels during this season, check current rates on Trip.com.
Essential Travel Tips
Invest in a Ventra card or use the Ventra app for Chicago's 'L' trains and buses. It's way cheaper than buying single ride tickets, and you can easily transfer between buses and trains within two hours for free. Plus, it's the only way to get to Midway and O'Hare airports via public transit.
Don't leave Chicago without trying a deep-dish pizza, but know that it's more of a 'knife and fork' meal than a foldable slice. For an authentic experience, head to Lou Malnati's or Pequod's Pizza – just be prepared for a wait, especially on weekends. It's a Chicago rite of passage!
Take advantage of Chicago's free attractions! Millennium Park (home to 'The Bean'), Lincoln Park Zoo, and the Art Institute of Chicago (on certain days/times for Illinois residents, but still worth checking for general admission deals) offer incredible value. Pack a picnic to enjoy in one of the many beautiful parks to save on lunch costs.
Chicagoans are generally friendly but can be direct; don't mistake a straightforward conversation for rudeness. We also have a strong sense of neighborhood pride, so if you ask for directions, people will often tell you which neighborhood you're in or heading towards. Embrace the local lingo – 'the Loop' refers to the downtown business district.
Pack layers, no matter the season! Chicago weather is notoriously fickle, especially near Lake Michigan. Even in summer, evenings can get cool, and a light jacket or sweater is a must. In winter, be prepared for wind chills that can make it feel much colder than the thermometer indicates.
Stick to well-lit, populated areas, especially at night, just like any major city. While Chicago is generally safe, be aware of your surroundings, particularly in tourist-heavy spots where pickpocketing can occur. Keep valuables secure and avoid displaying expensive electronics openly.
💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Frequently Asked Questions
When's the absolute best time to visit Chicago, and what should I pack?
For that quintessential Chicago experience, aim for late spring (May-June) or early fall (September-October). The weather is usually pleasant for exploring the lakefront and parks, and you'll avoid the peak summer heat and crowds. Regardless of the season, always pack layers!

Beyond the Magnificent Mile, where can I find truly unique shopping experiences?
Skip the chain stores and head to neighborhoods like Wicker Park and Lincoln Park for independent boutiques and vintage shops. Andersonville is fantastic for quirky gifts and artisan crafts, and you'll find some real treasures if you're willing to explore a bit. Don't be afraid to pop into smaller storefronts; that's where the real gems are often hidden.
How do I get around Chicago like a local, and is the 'L' really that efficient?
The 'L' train system is your best friend for navigating the city efficiently and affordably.

Grab a Ventra card or use contactless payment for easy tap-and-go access; it's much simpler than fumbling for cash.
What are some 'must-do' Chicago activities that aren't in every guidebook?
While the big museums are great, consider exploring the Garfield Park Conservatory, one of the largest and most stunning indoor gardens in the country, especially lovely on a chilly day.
