11 Must-Take Scenic Routes In Illinois For 2026

Illinois hides far more than endless fields and familiar skylines. Some of its most memorable moments appear along quiet roads where rivers bend, bluffs rise, and small towns carry stories that refuse to fade.

In 2026, the legendary Route 66 reaches its 100th year, turning Illinois into a living time capsule for road trip lovers. Every mile reveals something unexpected.

One stretch winds past sandstone canyons shaped by ancient water, another climbs into hill country that feels worlds away from the prairie. Historic downtowns, roadside diners, and river overlooks keep the journey constantly changing.

These scenic drives show a side of Illinois many people never imagine. The experience is less about the destination and more about the moments in between, where history, landscape, and curiosity meet in the most surprising ways.

1. Historic Route 66 Centennial Drive (Chicago To St. Louis)

Few roads carry as much legend as Route 66, and 2026 is the year it all comes full circle. The highway turns 100 years old this year, and Illinois is throwing a centennial celebration that stretches all 301 miles from Chicago to St. Louis.

Towns like Joliet, Pontiac, and Springfield are packed with events, museums, and newly restored landmarks honoring the Mother Road’s century-long run.

Pontiac is a must-stop, home to the Route 66 Hall of Fame and Museum, where you can spend a solid hour getting lost in neon signs, vintage gas pumps, and road maps from another era. Springfield offers the Abraham Lincoln Presidential Library nearby, making this drive a double dose of American history.

The retro kitsch factor is off the charts, from giant statues to classic diners still serving burgers the old-fashioned way.

Plan at least three days to do this route justice. Early fall is a sweet spot for comfortable temperatures and thinner crowds.

Pack a road trip playlist, grab a paper map for the nostalgia of it, and enjoy every mile of this once-in-a-generation centennial drive.

2. Great River Road (Mississippi River Corridor)

Running parallel to the mighty Mississippi, the Great River Road in Illinois is one of those drives that makes you pull over every ten minutes just to stare.

Towering limestone bluffs rise above the river, and in winter and early spring, bald eagles gather in numbers that feel almost surreal. Small towns like Nauvoo, Galena, and Savanna dot the route, each with their own slice of frontier-era history.

The road is part of a multi-state National Scenic Byway that hugs the river from Minnesota all the way to the Gulf of Mexico, but the Illinois stretch has a character all its own.

Roadside pull-offs offer some of the best eagle-watching in the Midwest, especially near Lock and Dam No. 13 close to Fulton. Historic buildings, river ferry crossings, and family-run diners add texture to every mile.

Spring and fall are the golden windows for this drive.

Fall color reflects beautifully off the river, while spring brings migrating waterfowl and fresh green bluffs. Give yourself two days, keep your camera handy, and let the Mississippi set the pace for a drive that rewards patience at every bend.

3. Illinois River Road National Scenic Byway

Covering 291 miles through the heart of the Illinois River Valley, this National Scenic Byway is a nature lover’s road trip served on a silver platter. The route winds through a landscape shaped by glaciers, rivers, and centuries of wildlife migration.

Herons, egrets, and migrating songbirds are regular sights along the water’s edge, and the valley itself feels surprisingly wild for a state many people associate with flatlands.

The byway passes through towns like Peru, Lacon, and Havana, where riverside parks and boat launches invite you to slow down and linger.

Emiquon National Wildlife Refuge near Havana is one of the most significant wetland restoration projects in the country, and a visit there feels genuinely humbling. Kayakers and birdwatchers regularly share the shoreline in peaceful coexistence.

Late September through October brings the most dramatic scenery as the hardwood forests along the bluffs shift into full color. If you enjoy hiking, the trails at Starved Rock State Park connect naturally to this byway and add a canyon-level thrill to your journey.

This is a drive best enjoyed without a tight schedule, where every detour down a gravel road might just lead to something unforgettable.

4. Ohio River Scenic Byway (Southern Illinois Shawnee Hills)

Southern Illinois has a personality completely separate from the rest of the state, and the Ohio River Scenic Byway is the best way to feel that difference.

This route traces the northern bank of the Ohio River through the rugged Shawnee Hills, a region that feels more like Kentucky or Tennessee than the Illinois most people picture. Dense hardwood forests, rolling terrain, and river vistas keep the scenery constantly interesting.

The byway passes through small communities like Cave in Rock, famous for its riverside cave once used by river pirates in the early 1800s. Golconda is another highlight, a quiet town with historic buildings and a marina where the river feels close enough to touch.

Rosiclare, once known for its fluorspar mining, adds an industrial history layer to the natural beauty surrounding it.

Fall is unquestionably the best season here. The Shawnee Hills explode with orange, red, and gold, and the Ohio River reflects the colors in a way that feels almost theatrical.

Pack a picnic, plan your stops around the river towns, and take the time to walk down to the water’s edge at least once. This byway rewards those who treat it like a destination, not just a connector road.

5. Meeting Of The Great Rivers Scenic Route (Near Alton, Illinois)

Somewhere near the small city of Alton, Illinois, three of North America’s greatest rivers meet in a moment of geographic drama that most people drive past without ever knowing.

The Meeting of the Great Rivers Scenic Route highlights the junction of the Mississippi, Missouri, and Illinois rivers, and the overlooks along this drive offer views that are genuinely hard to put into words.

The route runs through river towns with deep histories, including Grafton, a charming community perched between the Illinois River and limestone bluffs.

Pere Marquette State Park sits right along the route and features one of Illinois’ most beloved lodges, built by the Civilian Conservation Corps in the 1930s. The park’s trails wind up to bluff-top overlooks that show all three rivers at once on a clear day.

Bald eagles are a major draw here from November through February, when hundreds gather along the river to feed on fish below the dams.

The Great Rivers National Scenic Byway interpretive center in Alton is a great first stop to orient yourself before heading out. This is a compact but deeply rewarding drive, perfect for a day trip from St. Louis or Springfield.

6. Lincoln Highway Scenic Byway (Northern Illinois)

Long before Route 66 captured the public imagination, the Lincoln Highway was already making history as the nation’s first coast-to-coast road.

The Illinois section of this storied route cuts through the northern part of the state, connecting towns that grew up around the highway and still carry its legacy in their bones. Dixon, DeKalb, and South Elgin each offer their own character, from presidential birthplaces to art deco architecture.

Dixon is worth a dedicated stop as the childhood home of President Ronald Reagan. The Reagan Boyhood Home is open for tours, and the town itself is a pleasant surprise with a walkable downtown and a riverside park along the Rock River.

Original Lincoln Highway markers, some dating back to the 1920s, still pop up along the route if you know where to look.

This byway rewards the historically curious traveler more than the scenery-seeker, though northern Illinois has its own quiet charm in the rolling farmland and small-town main streets.

Summer weekends often bring car shows and festivals tied to the highway’s heritage. If you appreciate the layered story of American road culture, this drive offers a front-row seat to where it all started, one small town at a time.

7. Historic National Road (Marshall To East St. Louis)

Before the railroads and the interstates, the National Road was the main artery of westward expansion in America. Illinois preserves a historic and scenic driving route that runs from Marshall near the Indiana border to East St. Louis, though the original National Road historically ended at Vandalia.

Driving it today feels like tracing the footsteps of pioneers, settlers, and traders who shaped the country’s early identity one muddy mile at a time.

Original stone mile markers still stand along parts of the route, and some historic S-bridges built in the early 1800s survive as quiet roadside landmarks.

Vandalia served as Illinois’ second state capital and is a key stop along the way, with a beautifully preserved statehouse that dates back to 1836. The building is small by today’s standards but carries an outsized sense of history.

Collinsville is another highlight near the eastern edge of the St. Louis metro area, home to Cahokia Mounds State Historic Site, a UNESCO World Heritage Site featuring ancient earthworks built by a civilization that flourished here around 1000 CE.

The National Road connects these dots in a way that makes Illinois feel genuinely ancient. Plan a full day and treat every historical marker as an invitation to stop and learn something new.

8. Shawnee National Forest Drive (Garden Of The Gods)

Rock formations that look like they belong in the American Southwest are hiding in the far southern corner of Illinois, and the drive through Shawnee National Forest to the Garden of the Gods is one of the most surprising road trips in the entire state.

The ancient sandstone formations rise above the forest canopy in shapes that seem almost sculpted by hand, with names like Camel Rock, Table Rock, and Devil’s Smokestack that match their silhouettes perfectly.

The access road off Illinois Route 34 near Herod winds through thick forest before opening up to the trailhead parking area. From there, the Observation Trail is a short but dramatic walk that puts you on top of the formations with panoramic views stretching into Kentucky on a clear day.

Fall is the undisputed best time to visit, when the hardwood forest surrounding the rocks shifts into a full palette of warm colors.

Camping is available at the Garden of the Gods campground, and spending a night here means waking up to a silence that feels genuinely rare. The nearest town is Harrisburg, about 15 miles north, where you can stock up before heading into the forest.

This drive is proof that Illinois has genuine wilderness, and it is well worth the detour to the state’s far southern edge.

9. Illinois Route 127 Through The Shawnee Hills

Route 127 through the Shawnee Hills is one of those roads that locals know and visitors overlook, which is exactly what makes it so good.

The highway rolls through the heart of southern Illinois with a rhythm that feels almost meditative, passing orchards, farmstands, and stretches of forest that open unexpectedly onto wide valley views. The landscape here is genuinely hilly in a way that catches first-time visitors off guard.

Murphysboro and Carbondale sit along or near this corridor, giving travelers a handful of urban amenities without breaking the rural spell.

The Alto Pass area is a particular highlight, perched on a ridge with sweeping views in multiple directions and a handful of small businesses that have been serving the community for generations. The natural beauty here shifts dramatically with the seasons, from spring wildflowers to summer green to autumn fire.

Southern Illinois’ reputation as a growing destination for outdoor recreation is well earned, and Route 127 connects several of the region’s best hiking and nature areas in a single logical drive.

Giant City State Park is reachable with a short detour and absolutely worth it for its massive stone formations and shaded trails. This route is best driven slowly, with the windows down and no particular deadline waiting on the other end.

10. Galena’s Historic Corridor (US-20, Northwestern Illinois)

Northwestern Illinois looks nothing like the rest of the state, and US-20 through Galena’s historic corridor is the most scenic way to experience that fact.

The road rises and dips through a landscape shaped by ancient glacial activity that somehow missed this corner of Illinois, leaving behind rolling hills that feel more like the Driftless Region of Wisconsin than anything you might expect from the Prairie State.

Galena itself is one of the most beautifully preserved 19th-century towns in the Midwest, with a main street lined with brick storefronts, Victorian homes climbing the hillsides, and more than 85 percent of its buildings listed on the National Register of Historic Places.

Ulysses S. Grant lived here before the Civil War, and his restored home is open for tours year-round.

The town has a magnetic pull that keeps visitors coming back season after season.

The drive along US-20 approaching Galena from the east offers a sweeping panorama of the town and the Galena River valley that genuinely stops traffic. Autumn turns this corridor into something extraordinary, with the hillsides glowing in amber and crimson.

Plan a full weekend, explore the surrounding countryside on the quiet county roads, and let Galena remind you that small towns can carry enormous character.

11. Starved Rock State Park Drive (IL-71 Along The Illinois River)

Driving IL-71 along the Illinois River toward Starved Rock State Park is one of those experiences that earns a permanent spot in your road trip memory.

The park is anchored by 18 sandstone canyons carved by glacial meltwater at the end of the last Ice Age, and the drive along the river leading up to it builds anticipation in the best possible way. Utica is the gateway town, small but perfectly positioned as a base for exploring the park.

Spring is the prime season for this route. Snowmelt feeds the canyon waterfalls from March through May, turning Starved Rock into a destination that photographers plan trips around months in advance.

The falls inside LaSalle Canyon and St. Louis Canyon are among the most photographed natural features in Illinois, and for good reason. Seeing them in person after the winter thaw is a genuinely moving experience.

The Illinois River itself adds a scenic backdrop to the drive, with boat traffic, herons, and river bottomland forests framing the road as you approach the park.

Buffalo Rock State Park nearby features overlooks and massive animal-shaped earthwork sculptures known as the Effigy Tumuli that add a fascinating cultural layer to the natural drama. Come for the canyons, stay for the river views, and leave already planning your return trip in a different season.
