Georgia is the better state to visit if you want variety in one trip: a big city, a historic port, mountains and Atlantic beaches, with a long warm season. Illinois is the better pick if Chicago is the point, because few American cities match it for architecture, museums and food, and the rest of the state adds sandstone canyons, river towns and the first stretch of Route 66 in its centennial year.
The two states rarely end up on the same shortlist, but they answer the same question: which base city, and which side trips? Below is what each state is good for, when to go, what things cost and the rules worth knowing, checked against the National Park Service, state agencies and the City of Chicago in September 2026.
What each state is actually for
Georgia is a road trip state. Atlanta is the hub, with Martin Luther King Jr. National Historical Park, big museums and a serious food scene. Savannah, about four hours southeast, is the state’s historic showpiece, laid out around shady public squares in the colonial era. The north Georgia mountains bring hiking, waterfalls and the southern end of the Appalachian Trail at Springer Mountain, and the Golden Isles give you Atlantic beaches and salt marsh.
Illinois is Chicago plus a long, quiet state. Chicago alone justifies the trip: the architecture along the river, the Art Institute of Chicago, the Field Museum, Millennium Park and a lakefront lined with beaches and trails. Beyond the city, Illinois rewards travelers who like small places: the canyons of Starved Rock, the preserved 1800s downtown of Galena, Abraham Lincoln’s Springfield and the sandstone bluffs of Shawnee National Forest at the southern tip.

Georgia: where to spend your days
Atlanta works best as a two day stop. Martin Luther King Jr. National Historical Park on Auburn Avenue charges no entrance fee and covers King’s birthplace neighborhood and Ebenezer Baptist Church. Downtown has the Georgia Aquarium and Centennial Olympic Park, and the Atlanta BeltLine trail links neighborhoods full of good restaurants. MARTA’s Red and Gold lines start at the airport’s domestic terminal and run to downtown and Midtown.
Savannah is the stop people remember. The historic district is built around a grid of public squares shaded by live oaks and Spanish moss, and it is best explored on foot. Forsyth Park, River Street and the house museums fill two days easily, and Tybee Island, the city’s beach, is a short drive east.
The mountains are a couple of hours north of Atlanta. Blue Ridge has a walkable downtown and the Blue Ridge Scenic Railway along the Toccoa River, Dahlonega adds gold rush history and wineries, and Amicalola Falls State Park is the traditional start of the approach trail to Springer Mountain. Georgia State Parks charge a $10 daily ParkPass per vehicle, or $70 for a year.
The Golden Isles on the southern coast include St. Simons Island, Sea Island, Little St. Simons Island and Jekyll Island. Jekyll charges $10 per vehicle per day, read from your license plate at the gate, or $100 for an annual pass. Farther south, Cumberland Island National Seashore is reached by ferry from St. Marys. The National Park Service charges $15 per person age 16 and older for a seven day pass, and the ferry fare is separate.
Illinois: where to spend your days
Give Chicago at least three days. An architecture river cruise is the best introduction to the city. The Art Institute and the Field Museum are world class, Millennium Park and the lakefront trail are free, and neighborhoods such as Pilsen, Logan Square and Hyde Park show the city beyond the Loop.
Starved Rock State Park, an easy day trip southwest of Chicago, is the state’s best known natural area: 18 canyons cut into St. Peter Sandstone, more than 13 miles of trails, and waterfalls fed by rain and snowmelt. It became the second state park in Illinois in 1911. The Illinois Department of Natural Resources warns that some trails could be closed or limited throughout 2026 for trail improvements, so check before you drive out.
Galena, in the far northwest corner near the Mississippi River, is a preserved 1800s river town with a long main street of brick storefronts and the home of Ulysses S. Grant. Route 66 begins in downtown Chicago and runs about 300 miles across Illinois through Joliet, Wilmington, Pontiac and Springfield, according to the state tourism office. In Springfield, Lincoln Home National Historic Site offers free ranger led tours, with tickets from the visitor center and parking at $2 an hour. The highway marks its centennial in 2026, so expect events and busier motels along the route.
At the opposite end of the state, Shawnee National Forest has bluffs, rock formations and forest trails that surprise anyone who thinks Illinois is flat. The Forest Service calls its Garden of the Gods area one of the most photographed locations in the state. It sits closer to St. Louis and Nashville than to Chicago, so pair it with those cities.
Seasons and weather
Georgia’s best seasons are spring and fall. March through May brings azaleas and comfortable temperatures in Savannah and Atlanta, and October and November bring mountain color and pleasant coast days. Summer is hot and humid across the state with frequent afternoon storms, and the Atlantic hurricane season runs from June through November, which matters on the coast. Winter is mild in the south and occasionally icy in the mountains.
Chicago is at its best from late May through early October, when the lakefront, beaches and street festivals are all in play. Winter is long, gray and windy, though the museums make a winter city break workable. Starved Rock’s waterfalls flow best after spring rain and snowmelt, and fall color in the canyons and around Galena usually arrives in October.
Costs and getting around
Neither state is expensive outside its main city, but the costs look different. The Georgia Department of Revenue collects a flat $5 state fee per room per night on hotels and on short term rentals booked through online marketplaces, and park fees add up: $10 a day at state parks and another $10 a day to drive onto Jekyll Island. Chicago’s costs sit in hotels and parking. The City of Chicago charges a 4.5 percent hotel accommodations tax on top of state hotel taxes, plus a 6 percent surcharge on vacation rentals and shared housing, so compare prices after tax.
Georgia is a driving state. The mountains and the coast sit at opposite ends, so give each region a few days rather than zigzagging. Illinois is the reverse: Chicago is one of the easiest American cities to see without a car. The CTA Blue Line runs to O’Hare around the clock, taking about 40 to 45 minutes to downtown, and the Orange Line reaches Midway in about 20 to 25. Rent a car only for the day trips.
Which traveler should pick which
Pick Georgia if you want warm weather, Southern food and civil rights history, a mix of city, mountains and beach in one trip, and you are happy to drive. It shines in spring and fall.
Pick Illinois if you love cities, museums, architecture and restaurants, you would rather not drive, or you are a road trip fan who wants Route 66 in its centennial year. It shines from late spring through early fall.
Comparing other trips? Our Minnesota or Tennessee travel comparison and our look at Connecticut or Indiana use the same approach. If you are thinking about moving rather than visiting, see Georgia against Maryland and Michigan against Illinois.
Planning tips and mistakes to avoid
Treating Cumberland Island as a casual stop. Ferry seats are limited, so book ahead, and plan your whole day around the return sailing.
Driving into the Loop. Downtown Chicago parking is expensive and rarely necessary. Leave the car at the hotel, or skip renting one until you head for Starved Rock or Galena.
Skipping the trail check at Starved Rock. With 2026 trail work under way, confirm which trails are open before a long drive, and arrive early on spring weekends.
Trying to see all of Georgia in a long weekend. Atlanta to Savannah is about four hours by car, and the mountains are in the opposite direction. Pick two regions at most for a short trip.
Booking Route 66 motels late. Centennial events in 2026 mean small towns on the route can fill up, so reserve early if your dates are fixed.
Frequently asked questions
Is Georgia or Illinois cheaper to visit?
Outside Chicago, both are affordable. Chicago hotels carry a 4.5 percent city tax on top of state taxes, while Georgia adds a flat $5 per room per night. Georgia’s extra costs are fees and fuel: $10 a day at state parks, $10 a day on Jekyll Island, and long drives between regions.
Can you visit Chicago without a car?
Yes, and it is the better way. The CTA Blue Line runs from O’Hare 24 hours a day and takes about 40 to 45 minutes to downtown, and the Orange Line reaches Midway in about 20 to 25 minutes. Trains and buses cover most neighborhoods. Rent a car only for trips beyond the city.
When is the best time to visit Savannah?
Spring and fall. March through May brings azaleas and comfortable walking weather, while October and November stay warm and pleasant for exploring on foot. July and August are hot and humid, with frequent afternoon storms. Book spring weekends early, because inns in the historic district fill quickly.
Is Starved Rock worth a day trip from Chicago?
Yes, if you like hiking. Its 18 sandstone canyons and more than 13 miles of trails are unlike anything else near Chicago, and the waterfalls are best after spring rain. Go early on weekends, and check the Illinois Department of Natural Resources site first, because some trails may be closed during 2026 improvements.
Where does Route 66 start in Illinois?
Route 66 begins in downtown Chicago and runs about 300 miles across Illinois toward St. Louis. Classic stops include Joliet, Wilmington, Pontiac and Springfield, home of Lincoln Home National Historic Site. The road dates to 1926, so 2026 brings centennial events and busier motels along the way.
The bottom line
Georgia is the better choice for a varied road trip in mild weather: Atlanta’s history and food, Savannah’s squares, mountain waterfalls and quiet barrier islands. Go in spring or fall and plan on driving.
Illinois is the better choice when a great city is the goal. Chicago is worth the trip on its own and easy to do without a car, and Starved Rock, Galena and Route 66 turn a city break into a fuller week, especially during the road’s centennial year.
