About
Illinois, the “Land of Lincoln” in the American Midwest, is a populous heartland state stretching from the shores of Lake Michigan to the Mississippi River, with Springfield as its capital and Chicago as its largest city. Admitted as the 21st state on December 3, 1818, it pairs big-city energy with vast prairie—earning its other nickname, the “Prairie State.” Chicago, the nation’s third-largest city with about 2.7 million residents, anchors the northeast with landmarks like Millennium Park, the Art Institute, and a skyline born of modern architecture. Springfield preserves the legacy of Abraham Lincoln, from his home to his tomb and presidential library. Beyond the metropolis, travelers find Route 66 nostalgia, the rolling Shawnee National Forest in the south, and river towns along the Mississippi. Strategically linked by the Great Lakes and the Mississippi system, Illinois has long been a crossroads of American transport, agriculture, and culture.
Best time to visit
Late May through October offers the best weather (21–29 °C) and the city’s legendary festival season, including Taste of Chicago, Lollapalooza, and the Air & Water Show. September–October balances warm days, fall foliage, and smaller crowds. Winter (December–February) is bitterly cold but rewards with low hotel rates and holiday festivities.
Season by season
Spring (Apr–May): 10–20 °C, tulips in Millennium Park, occasional rain, baseball season starts. Summer (Jun–Aug): 25–32 °C, peak tourism, beach weather, festivals galore. Autumn (Sep–Nov): 8–20 °C, stunning foliage, Chicago Marathon (Oct), fewer crowds. Winter (Dec–Feb): -8 to 2 °C, Christkindlmarket, ice skating, lowest hotel rates.
Crowds
Very High in summer (June–August), especially during festivals; moderate in spring/fall; low in winter
Getting there and around
Getting there
Illinois is primarily accessed through Chicago’s two major airports: O’Hare International (ORD), one of the world’s busiest airports with extensive international connections, and Midway International (MDW), focusing on domestic flights. The CTA Blue Line provides 24-hour service from O’Hare to downtown Chicago ($2.50), while the Orange Line connects Midway to the Loop (20-25 minutes, $2.50). Amtrak hub at Union Station serves routes from across the country including the Empire Builder, California Zephyr, and City of New Orleans. Major interstates I-90, I-94, I-55, I-57, and I-80 converge in Chicago. Regional airports include Quad Cities International (MLI) and General Wayne A. Downing Peoria International (PIA).
Getting around
Chicago’s CTA operates the nation’s second-largest public transit system with 8 color-coded ‘L’ (elevated) train lines and 129 bus routes. The Ventra Card provides seamless payment across CTA and Pace suburban buses ($2.50 per ride, $5 day pass, $20 weekly). Metra commuter rail extends to suburbs with 11 lines radiating from downtown terminals. Outside Chicago, cities like Springfield, Rockford, and Peoria have limited local bus service. Illinois has extensive toll roads (I-PASS recommended for frequent travel). Ride-sharing operates statewide, though less available in rural areas. Chicago is highly walkable in neighborhoods like the Loop, River North, and Lincoln Park, while downstate cities typically require cars.
Top experiences in Illinois

Art Institute of Chicago
One of the world’s premier art museums, housing 300,000+ works spanning 5,000 years. Must-sees include Grant Wood’s American Gothic, Seurat’s A Sunday on La Grande Jatte, and an extensive Impressionist gallery. Adult admission is $35; Illinois residents receive discounted access on select days.

Tips from the field
Highlights
- Cloud Gate (The Bean) – Millennium Park
- Art Institute of Chicago
- Willis Tower Skydeck
- Chicago Architecture Boat Tour
- Deep-Dish Pizza
- Navy Pier
- Wrigley Field
- Lincoln Park Zoo (Free)
Best activities
- Photograph Cloud Gate in Millennium Park, take a Chicago Architecture Foundation river cruise, explore the Art Institute's Impressionist galleries, walk the Riverwalk at dusk, ride the Centennial Wheel at Navy Pier, taste deep-dish pizza at Lou Malnati's, catch a Cubs game at Wrigley Field, visit the free Lincoln Park Zoo, stroll through the Magnificent Mile, and see live blues at Kingston Mines in Lincoln Park.
Local experiences
- Join a deep-dish pizza-making class, attend a blues jam at Rosa's Lounge, explore the street art and galleries of Pilsen, kayak the Chicago River at sunrise, or visit the Maxwell Street Market on Sundays for tacos and live music.
Practical tips
- Transport: CTA 'L' trains and buses cover the city; buy an unlimited-ride pass (1/3/7-day) for best value.
- Tipping: 18–20 % at restaurants; $1–2 per drink at bars.
- Wind: Chicago earns its 'Windy City' nickname—layer up, especially along the lakefront.
- Parking: Skip the rental car; parking downtown is $40–70/day.
- Free Days: Many museums offer free admission days—check schedules online.
Photography tips
- Cloud Gate reflects the skyline best in the first hour after sunrise before crowds arrive. For the classic Chicago skyline shot, head to Adler Planetarium's lakefront viewpoint at blue hour. The 'L' train framing downtown buildings makes a great subject from Wells Street. The Riverwalk offers reflections of Marina City's 'corn cob' towers. Navy Pier's Centennial Wheel provides an elevated perspective of the lakefront at sunset.
Timing
- Allow 3–5 days for Chicago's core attractions. A long weekend covers Millennium Park, the Art Institute, a river cruise, deep-dish pizza, and one neighborhood walk. Add days for day trips to Starved Rock State Park (90 min) or Galena (150 min) in the countryside.
Keeping it authentic
- Chicago's identity is built on layers: the architectural rebirth after the 1871 fire, the blues and jazz clubs that gave the city its soundtrack, the immigrant neighborhoods—Polish in Avondale, Mexican in Pilsen, Italian on Taylor Street—that still define distinct pockets of the city. Deep-dish pizza at Lou Malnati's or Giordano's is a civic ritual, as is the Italian beef sandwich. The 'L' elevated train is both transit artery and city icon, and catching a Cubs game at Wrigley Field remains a quintessential Chicago experience.
Culture, customs and safety
Cultural heritage
Illinois boasts a rich tapestry of cultural and historical heritage rooted in both Indigenous civilizations and industrial innovation. The Cahokia Mounds, a UNESCO World Heritage site near Collinsville, preserve the remnants of the largest pre-Columbian settlement north of Mexico, reflecting the advanced Mississippian culture. Chicago, rebuilt after the Great Fire of 1871, became a birthplace of modern architecture, with pioneering skyscrapers and the influential Prairie School led by Frank Lloyd Wright. The state also played a pivotal role in the Underground Railroad, the labor movement, and the civil rights struggle. From jazz and blues in Chicago’s South Side to Abraham Lincoln’s legacy in Springfield, Illinois reflects a dynamic interplay between historical preservation and cultural reinvention.
Local customs & etiquette
Illinois culture centers on Midwestern hospitality with Chicago’s urban sophistication. Deep-dish pizza is a point of pride – order at Giordano’s or Lou Malnati’s, never compare to New York style. Sports loyalty runs deep: Cubs vs White Sox divides families, Bears dominate fall Sundays, Bulls and Blackhawks maintain devoted followings. Tipping standard is 18-20% in restaurants, $1-2 per drink at bars. Chicago embraces its architecture – boat tours are locals’ favorite way to show off the city. “Dibs” system reserves shoveled parking spots with chairs in winter. Downstate Illinois maintains agricultural roots with county fairs, corn festivals, and Lincoln heritage sites. Business culture is more formal in Chicago’s Loop, casual elsewhere.
Safety notes
Chicago’s major tourist areas—the Loop, Magnificent Mile, River North, Navy Pier, Lincoln Park, and Wicker Park—are generally safe. Pickpocketing occurs in crowded areas; keep valuables secure and stay aware on public transit. Avoid walking alone in poorly lit areas after dark, especially west of State Street in the Loop. Use rideshares (Uber/Lyft) at night. Emergency: 911.
