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.

Essential Travel Tips

transport

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.

food

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!

money

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.

culture

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.

packing

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.

safety

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.

GoWithGuide Tours and Experiences

Getting Around Chicago, Illinois, USA

CTA 'L' Trains

Chicago's elevated and subway train system, the 'L', is the backbone of public transit, connecting O'Hare and Midway airports to downtown and many neighborhoods. It's efficient for covering longer distances and avoiding traffic.

Cost:$2.50 per ride with Ventra card, $5 for a 1-day pass.
Tip:Get a Ventra card (available at stations) or use your contactless credit/debit card for easy tap-and-go payment. Avoid rush hour (7-9 AM, 4-6 PM) if you dislike crowds. Don't stand in the doorway; move to the center of the car. The Blue Line goes to O'Hare, the Orange Line to Midway.

CTA Buses

The extensive bus network complements the 'L' trains, reaching areas not served by rail and offering more granular access within neighborhoods. They are great for shorter hops or when your destination is a few blocks from an 'L' station.

Cost:$2.50 per ride with Ventra card, transfers to 'L' trains are free within 2 hours.
Tip:Use the Ventra app to track buses in real-time – it's a lifesaver. Have your fare ready before boarding to avoid holding up the line. Be aware that buses can get stuck in traffic, so factor in extra time, especially during peak hours.

Divvy Bike Share

Chicago's bike-share program offers a fun and active way to explore the city, especially along the lakefront trail and through neighborhoods. It's perfect for short trips and enjoying the scenery at your own pace.

Cost:$1 to unlock, then $0.17/minute for classic bikes, $0.34/minute for e-bikes. Day passes and memberships are available.
Tip:Download the Divvy app to find stations and unlock bikes. Always wear a helmet (though not legally required for adults, it's highly recommended). Be mindful of pedestrians on the lakefront trail; stick to the bike lanes and follow traffic laws.

Ride-Sharing Services (Uber/Lyft)

Ubiquitous in Chicago, Uber and Lyft offer convenient door-to-door service, particularly useful for late-night travel, getting to/from airports with luggage, or when traveling in small groups. They are generally more expensive than public transit.

Cost:Varies widely based on demand, time of day, and distance. Expect $15-$40 for typical downtown trips.
Tip:Check surge pricing before booking; sometimes waiting 10-15 minutes can significantly reduce the fare. Be aware of your pickup location, especially in busy areas like Magnificent Mile or Millennium Park, as drivers may have trouble finding you.

Water Taxis

During the warmer months (typically May-September), Chicago Water Taxis offer a unique and scenic way to travel between popular downtown attractions along the Chicago River and Lake Michigan. It's a delightful way to see the city's architecture from a different perspective.

Cost:Around $10-$15 per ride, with day passes available for around $30-$40.
Tip:Check their schedule and routes online as they are seasonal and weather-dependent. Boarding can be crowded, so arrive a bit early. Avoid trying to hail them like a taxi; they operate from designated docks.

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! Chicago weather can change on a dime, so a waterproof jacket and comfortable walking shoes are non-negotiable, even in summer.

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. It connects most major attractions and neighborhoods, and it's usually faster than dealing with traffic, especially during rush hour. 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. Also, catch a show at one of the many smaller, independent theaters in the Lakeview or Uptown neighborhoods for a taste of Chicago's vibrant performing arts scene beyond Broadway.

I'm on a budget. What are some ways to enjoy Chicago without breaking the bank?

Chicago offers plenty of free fun! Stroll along the lakefront trail, explore Millennium Park (home to 'The Bean'), and enjoy free admission days at many museums (check their schedules in advance).

What's a common Chicago food I absolutely have to try, and where should I go?

You can't leave Chicago without trying an authentic deep-dish pizza, but skip the most famous tourist spots.
