Why Visit Illinois #

Chicago’s culinary identity goes well beyond deep-dish: hunt down Italian beef sandwiches, neighborhood pizza at Lou Malnati’s or Pequod’s, and a Chicago-style hot dog with everything on it. Visit the West Loop for fine dining and Fulton Market for inventive small plates. Expect crowds, but quality is consistently high.

A river cruise is the best way to read Chicago’s skyline: you’ll see Loop skyscrapers, the Rookery, and modern glass towers while guides explain structural innovations. Walk the Riverwalk afterward and hit the Art Institute for a few hours; architecture here is a living museum rather than a static collection.

Illinois is where Route 66 begins - small towns like Pontiac and Joliet preserve neon signs, diners and classic Americana. Drive parts of the original alignment to visit kitschy museums and restored motels. It’s an accessible slice of midwestern road-trip nostalgia and a good counterpoint to urban Chicago.

Springfield concentrates Lincoln’s life: the Abraham Lincoln Presidential Library and Museum is a polished, immersive introduction, while the Lincoln Home National Historic Site and his tomb feel quieter and more reflective. History buffs should allow a full day to absorb the exhibits and walking tour of the governor’s mansion area.

Who's Illinois For?

Couples

Chicago’s skyline dinners, riverwalk cruises and rooftop bars create elegant date nights; explore Lincoln Park Conservatory or the Art Institute for cultured daytime outings.

Families

Shedd Aquarium, Field Museum and Navy Pier provide world-class, kid-friendly experiences; beaches along Lake Michigan add outdoor days in summer.

Backpackers

Hostels cluster around downtown Chicago for budget travelers, but Illinois isn’t a classic backpacker destination-urban stays dominate over wilderness trails.

Digital Nomads

Chicago offers strong coworking, transit, and cultural perks; city living is expensive, but neighborhoods like Logan Square provide affordable alternatives and café workspaces.

Foodies

From iconic deep-dish pizza and Chicago dogs to vibrant ethnic neighborhoods and acclaimed fine dining, the city’s culinary range satisfies adventurous eaters.

Adventure Seekers

Starved Rock State Park and northern Illinois bluffs offer solid day hikes and canyoneering-style routes, but extreme alpine-style adventures are limited compared to the Rockies.

Party Animals

Wrigleyville, River North and Fulton Market host energetic bar scenes and live music; Chicago nightlife blends clubs, comedy and legendary blues joints.

Nature Buffs

Lake Michigan’s shoreline, the Rock Island Trail and Shawnee National Forest’s sandstone gorges provide accessible natural diversity for hikers and birdwatchers.

Getting to & Around Illinois #

Chicago’s airports (ORD, MDW) and Chicago Union Station are the main gateways for Illinois. Many long‑distance Amtrak routes and commuter lines radiate from Chicago; passengers traveling to suburbs and downstate cities often transfer to Metra or drive. ORD offers direct flights to most U.S. and international destinations, making it the usual arrival point for long‑haul visitors.

Illinois is dominated by the Chicago metro area: extensive urban rail and bus networks in Chicago are far more comprehensive than public transit elsewhere in the state. Outside the Chicago region, rail is limited and driving becomes the norm for intercity travel.

  • Airports - Chicago O’Hare (ORD) and Midway (MDW) are the principal international gateways; additional service is available at smaller regional airports. ORD is one of the country’s largest hubs for domestic and international connections.
  • Trains - Chicago is a national rail hub: Amtrak and commuter services converge at Chicago Union Station, with intercity routes such as the California Zephyr and Hiawatha Service. For suburban and regional travel around Chicago use Metra commuter rail.
  • Local Transit - Within Chicago the CTA operates an extensive ‘L’ rapid transit system and buses; this level of urban transit is far greater than in the rest of Illinois. Downstate travel is primarily by road or infrequent intercity rail.
  • Rental Car - A rental car is recommended for exploring downstate Illinois-major highways include I‑55 to St. Louis, I‑80 across northern Illinois and I‑57/I‑70 for other corridors. Distances and rural coverage make driving the practical option outside Chicago.

Where to Stay in Illinois #

Illinois is dominated by Chicago’s broad hotel market, from hostels to luxury skyline properties. Outside the metro area there are B&Bs in historic towns like Galena and outdoor lodges in the southern Shawnee region, with seasonal demand for natural areas.

Hotels & Resorts
$120-350 Chicago; $80-160 elsewhere

Chicago’s Loop, River North and the Magnificent Mile contain the largest hotel options, from business hotels to luxury chains. Downstate cities like Springfield and Rockford offer reliable mid-range stays.

Hostels & Guesthouses
$25-65 / night

Hostels cluster near downtown Chicago, Lincoln Park and around major transport hubs, offering budget dorms and private rooms. Good choices for solo travelers and short urban stays.

Boutique Hotels
$150-300 / night

West Loop, Wicker Park and Fulton Market have boutique hotels with designer interiors and local dining options. These are convenient for food-focused travelers and those wanting neighborhood character.

Bed & Breakfasts & Historic Inns
$90-200 / night

Galena and Springfield feature well-regarded B&Bs and historic inns housed in 19th-century buildings. Ideal for heritage tourism and quieter weekend getaways in picturesque small towns.

Cabins & Lodges
$80-180 / night

Shawnee National Forest and Starved Rock State Park provide cabins, lodges and small inns for outdoor-focused stays. These are practical bases for hiking, birding and river activities in southern Illinois.
