Illinois is a state defined almost entirely by one city and one road: Chicago, a genuine world-class metropolis on Lake Michigan’s shore, and Route 66, whose original eastern terminus starts right in Chicago’s Loop before running southwest through a string of small towns still leaning hard into their neon-sign, mid-century-diner heritage.
Between them sits Springfield, Abraham Lincoln’s adopted hometown and the state capital, offering a genuinely deep dive into Lincoln’s life without the crowds of bigger presidential sites elsewhere. This guide covers Illinois three ways — budget, family, and luxury — with real costs, a sample itinerary, and a map.
Getting Oriented
Chicago: the Loop and Magnificent Mile handle downtown’s skyscrapers and shopping; Millennium Park’s “The Bean” (Cloud Gate) and Navy Pier anchor the lakefront; Lincoln Park Zoo (free) and the Museum Campus (Field Museum, Shedd Aquarium, Adler Planetarium, all clustered together) round out the major family draws.
Route 66 (Illinois stretch): starts at Chicago’s Buckingham Fountain and runs southwest through towns like Pontiac, Springfield, and Litchfield, dotted with vintage motels, giant roadside statues (the Gemini Giant, Cozy Dog Drive-In), and small-town museums dedicated to the “Mother Road.”
Springfield: home to the Abraham Lincoln Presidential Library and Museum, Lincoln’s Home National Historic Site, and his tomb at Oak Ridge Cemetery — genuinely one of the more comprehensive presidential history experiences in the country.
Galena: a well-preserved 19th-century town in the state’s northwest corner, notable as Ulysses S. Grant’s hometown and now a quiet weekend-getaway destination.
Chicago itself is best explored via the “L” train system and on foot; I-55 traces old Route 66 southwest toward Springfield and St. Louis, Missouri, just across the state line.
Neighborhood-hopping in Chicago rewards a little planning beyond the Loop. Wicker Park and Logan Square hold the city’s indie coffee-and-boutique energy; Pilsen’s murals and Mexican bakeries make a genuinely worthwhile detour; and Hyde Park, on the South Side, pairs the University of Chicago’s Gothic campus with the Museum of Science and Industry, one of the largest science museums in the Western Hemisphere and an easy full-day add-on to a Museum Campus itinerary.
Illinois on a Budget
Chicago has a reputation as an expensive big city, but its lakefront and many of its best sights are genuinely free.
Sleeping cheap. Chicago hostels run $40–75/night; budget hotels outside the Loop with L access run $100–150. Route 66 motels along the Illinois stretch run $70–100, many of them the same vintage neon-sign properties that made the road famous.
The best sights cost nothing. Millennium Park (including “The Bean”), Navy Pier’s exterior and views, Lincoln Park Zoo, and the entire lakefront path cost nothing. Route 66’s roadside attractions — giant statues, historic signage — are all free to photograph.
Eating cheap. A Chicago-style hot dog (never with ketchup, a genuine local rule) runs $4–7; deep-dish pizza splits well among a group for $20–30 total. The Cozy Dog Drive-In in Springfield, credited with inventing the corn dog, runs $5–8 a meal.
Budget total: $70–105 a day per person.
Illinois for Families
Chicago’s Museum Campus alone justifies a family trip, and it’s dense enough to cover multiple world-class attractions without much travel between them.
- Shedd Aquarium — one of the largest indoor aquariums in the world, with beluga whales and a genuinely engaging dolphin presentation.
- Field Museum — home to Sue, the largest and most complete T. rex skeleton ever found, alongside Egyptian mummies and an “Underground Adventure” exhibit kids remember for years.
- Adler Planetarium — sits right alongside the other two Museum Campus institutions, with genuinely good sky shows.
- Navy Pier — a Ferris wheel, carousel, and a children’s museum all clustered on a pier jutting into Lake Michigan.
- Lincoln Park Zoo — one of the few remaining free zoos in a major US city, genuinely well-maintained and a solid half-day.
Logistics: the Museum Campus is walkable between its three institutions, and a City Pass or Chicago CityPASS bundling multiple attractions often saves meaningfully if you’re doing three or more. The “L” train covers most of the city well; a car is more useful for the Route 66 corridor and Springfield.
Illinois in Luxury
Chicago’s luxury tier centers on the Magnificent Mile and the Gold Coast — the Peninsula, the Langham, and the Waldorf Astoria all offer skyline or lake views from roughly $500–1,000/night, with the city’s genuinely excellent fine-dining scene (Alinea, a three-Michelin-star pioneer of modernist cuisine, anchors the top tier) as a major draw in its own right.
Outside the city, Galena’s restored 19th-century inns and a handful of boutique properties along the Route 66 corridor offer a quieter, more historic version of luxury. What money best buys in Illinois: a private architecture river cruise (Chicago’s skyline is genuinely one of the great architectural showcases in the world, and a guided boat tour explains why), a table at one of the city’s destination tasting-menu restaurants booked well ahead, and a Lincoln Presidential Library private after-hours tour in Springfield.
The Highlights, Honestly Ranked
The Museum Campus (Shedd, Field, Adler) — genuinely world-class and walkable between each other; budget a full day minimum, two if possible. Millennium Park and “The Bean” — free, iconic, and worth an early-morning visit before crowds build. The Chicago Architecture River Cruise — one of the best-value tours in the country for understanding why the skyline looks the way it does. Route 66’s small-town stretch — a genuinely nostalgic, only-in-America drive if you have the extra day. Abraham Lincoln Presidential Library and Museum (Springfield) — surprisingly immersive and modern in its presentation, worth the detour from Chicago.
Food and Drink Worth Planning Around
Chicago’s food identity is fiercely specific: deep-dish pizza (Lou Malnati’s and Giordano’s both have devoted followings, and ordering it takes 30-45 minutes to bake, so plan ahead), the Chicago-style hot dog (all-beef, poppy seed bun, a specific set of toppings, and absolutely no ketchup — locals take this seriously), and Italian beef sandwiches (Al’s Beef is a classic starting point). Downstate, the Cozy Dog Drive-In in Springfield claims to have invented the corn dog in the 1940s and remains a genuine Route 66 pilgrimage stop. If you’re building a food day in Chicago, pair a deep-dish lunch (order it first, eat something else while it bakes) with a hot dog or Italian beef dinner to sample the city’s two signature styles.
Best Time to Visit
May–June brings Chicago’s most pleasant weather — warm enough for the lakefront, before peak summer humidity. September–October repeats that sweet spot with comfortable temperatures for the Museum Campus and Route 66 driving. July–August is peak season with the warmest weather but also the highest crowds and prices, plus genuine lakefront humidity. Winter turns brutally cold with wind off the lake — Chicago’s indoor attractions (museums, the Art Institute) still work well, but outdoor sightseeing is a different, harder experience.
Essential Gear & Must-Haves for Illinois
| Must-have | Why it matters here |

| Ventra card | Chicago’s transit fare card works across the L and buses |
| Layered clothing | Lake Michigan’s temperature moderation means genuine swings between downtown and inland |
| Camera with a wide lens | The skyline and river cruise both reward it |
| Sunscreen | Navy Pier and lakefront days both call for it |
| Full tank of gas | Route 66’s small towns have sparser gas stations than the interstate |

Where Is Illinois?
Illinois sits in the American Midwest along Lake Michigan’s southwestern shore, with Chicago in the state’s northeast corner. Springfield, the state capital marked on the map below, sits roughly 200 miles southwest, close to the historic Route 66 corridor and near the Missouri border.
Mistakes First-Timers Make in Illinois
Ordering deep-dish pizza last-minute. It takes 30-45 minutes to bake — order it first at any sit-down meal and eat something else while waiting.
Requesting ketchup on a Chicago hot dog. It’s a genuine local taboo — the accepted toppings (mustard, onion, relish, tomato, pickle, sport peppers, celery salt) don’t include it, and locals will notice.
Underestimating Chicago’s winter wind. The lakefront wind chill is genuinely brutal — this is not a season for extensive outdoor sightseeing without serious cold-weather gear.
Trying to drive Route 66 without checking current road status. Some historic segments have been bypassed or renamed — use a dedicated Route 66 map rather than just following GPS, which will route you onto the interstate instead.
Skipping Springfield as “just a detour.” The Lincoln sites are genuinely comprehensive and worth a dedicated day, not a rushed afternoon on the way to somewhere else.
A Note on Getting Around Without a Car
Chicago is one of the few cities in this guide where skipping a rental car entirely is a genuine option, not just a budget compromise. The L’s eight color-coded lines reach nearly every neighborhood covered above, O’Hare and Midway airports both connect directly to downtown by train, and the lakefront trail makes walking or biking between the Loop, Museum Campus, and Lincoln Park pleasant for most of the year. Save the rental car for the Route 66 and Springfield leg of the trip, where it’s genuinely required.
Frequently Asked Questions
How many days does Illinois need? Four days covers Chicago plus a Route 66/Springfield add-on comfortably; Chicago alone works well in 2-3 days.
Is Chicago family-friendly? Very much so — the Museum Campus, Navy Pier, and Lincoln Park Zoo are all built around family visits, and the “L” train is generally stroller-workable.
Do we need a car? Not for Chicago itself — the L and walking cover it well. For Route 66 and Springfield, yes.
Illinois or Missouri for a Route 66 trip? Illinois for the road’s actual starting point and small-town character; Missouri for the Gateway Arch and continuing the drive west.
Is Chicago safe for families? The main tourist areas (Loop, Museum Campus, Magnificent Mile, Lincoln Park) are well-trafficked and generally fine with normal city precautions; as with any major city, research specific neighborhoods if venturing beyond the core tourist areas.
Is the Museum of Science and Industry worth the trip to Hyde Park? Yes — it’s one of the largest science museums in the country, with a real German U-boat on display, and pairs naturally with a walk through the University of Chicago’s campus.
Should we buy a Chicago CityPASS? If you’re planning three or more paid attractions (Shedd, Field Museum, Skydeck, architecture cruise), it typically pays for itself and skips ticket lines at each stop.
Next Steps
Illinois pairs naturally with a wider Midwest road trip — Missouri’s Gateway Arch continues the Route 66 drive west, and Wisconsin’s Milwaukee is under two hours north of Chicago.
