Skip the interstate. Illinois River Road hits 10 counties and 100 wild stops

One road, ten counties, a thousand surprises

The Illinois River Road runs about 150 miles from Ottawa in the north down to Havana in the south, tracing both banks of the Illinois River through 10 counties. Over 100 natural and historic stops line the route.

You get sandstone canyons, seasonal waterfalls, bluff-top river views, enormous flocks of migrating birds, and a front-row seat to some of the deepest Native American history in the Midwest. The road doesn’t announce itself.

It just keeps delivering.

A valley carved by glaciers 12,000 years in the making

Long before anyone built a road here, glacial meltwater broke through the landscape and eroded the soft sandstone, leaving behind the bluffs and wide floodplains you’ll drive through today.

People have lived along this stretch of river for more than 12,000 years.

The Illinois people called this valley home, and French explorers came after them, then American settlers who followed the river west.

When Starved Rock got its name, it was already carrying a story, rooted in an 18th-century conflict between the Illiniwek and the Potawatomi.

Starved Rock’s 18 canyons cut into St. Peter Sandstone

Starved Rock State Park anchors the northern end of the byway and sets the tone for everything south of it.

The park covers roughly 2,630 acres and holds 18 sandstone canyons, their walls layered with moss-covered St. Peter Sandstone in shades of rust, gray and gold.

Illinois designated it a state park in 1911, and more than two million people come through each year, making it the most visited state park in the state. The canyon walls alone are worth the drive.

Waterfalls that freeze solid in January

The falls here run on their own schedule. Snowmelt and spring rain push them hardest in early spring, when water sheets down the canyon walls and pools at the bottom.

French Canyon, LaSalle Canyon and St. Louis Canyon hold some of the longer-lasting falls, though by midsummer most slow to a trickle until heavy rain brings them back.

Come in January and you’ll find those same waterfalls frozen into thick columns of ice, clinging to the sandstone walls from top to bottom.

Thirteen miles of trails through canyons and river bluffs

More than 13 miles of marked trails wind through Starved Rock, with color-coded posts keeping you on track through the canyons and along the river. Some paths run flat beside the water.

Others drop down into canyon floors where the light barely reaches midday. Overlooks along the route give you wide views of the Illinois River running below.

The sandstone butte the park takes its name from rises about 125 feet above the water, and you can stand on top of it and look straight down to the river’s edge.

Bald eagles hunting open water below the dam every January

Starved Rock is one of the top spots in the Midwest to watch bald eagles in winter.

They gather near the river’s lock and dam where open water stays below the dam even in the coldest months, and they hunt the fish that collect there.

You can watch from the bluff overlooks or walk down to the river’s edge for a closer look.

Every January the park hosts a popular eagle-watching weekend, drawing crowds with spotting scopes and telephoto lenses pointed at the same stretch of river.

Matthiessen’s Cascade Falls drops 45 feet between two dells

Just south of Starved Rock near Oglesby, Matthiessen State Park gives you about five miles of trails without the two-million-visitor crowd.

Groundwater seeps through the canyon walls here, staining the rock in wide bands of color. Cascade Falls drops about 45 feet where the Upper Dells meet the Lower Dells.

Two other stops, the Giant’s Bathtub and Lake Falls, draw their own steady stream of visitors. Check the Illinois DNR page before you go.

As of mid-2026, some waterfall-interior areas and the Lake Falls bridge were closed, and weekend parking fills by mid-morning from May through October.

The road Teddy Roosevelt called the world’s most beautiful drive

Grandview Drive winds about 2.5 miles along the bluffs above the Illinois River near Peoria. Workers built it by hand starting in 1903.

When President Theodore Roosevelt came through in 1910, he called it the most beautiful drive in the world, and the road has been on the National Register of Historic Places ever since.

Lookouts along the route open up wide views of the river valley below, and fall pushes those views to their best with color across the water and down the far bank.

Where the Illinois and Spoon rivers flow into each other

The Emiquon refuge sits at the point where the Illinois and Spoon rivers come together, protecting about 2,631 acres of restored wetlands. Lakes, marshes, prairies and upland terrain all run together here.

The wider Emiquon Complex carries a Ramsar Wetland of International Importance designation. Boardwalks, observation decks and trails let you explore on foot without a permit.

If you want to fish or launch a boat on the lake, you’ll need a lake-access permit and liability waiver. Digital forms are available online, and paper forms are at Dickson Mounds Museum during business hours.

Pelicans, ospreys and eagles crossing the Illinois River Valley

The Illinois River Valley sits along one of the great bird migration routes in North America.

Emiquon pulls large flocks of waterfowl in spring and fall, and if you time your visit right, you can spot bald eagles, ospreys and migrating pelicans from the observation decks.

Songbirds work through the bottomland forests in warmer months. The wetlands are wide and open, so bring binoculars or a spotting scope.

Without them, a lot of what’s moving out there stays too far away to read.

One hundred thousand ducks drop into Chautauqua in fall

Chautauqua National Wildlife Refuge sits just north of Havana and has been a sanctuary for migrating birds since 1936.

During fall migration, more than 100,000 ducks can fill its wetlands at once, and at peak times the lake can hold hundreds of thousands of waterfowl.

Boardwalks and observation decks along the bluff put you above the water with a clear line of sight.

Parts of the refuge close during fall and winter waterfowl season, so stop at refuge headquarters to find out which sections are open before you head to the water.

Dickson Mounds traces 12,000 years of life in the river valley

Near Lewistown at the southern end of the byway, Dickson Mounds Museum pulls together 12,000 years of human history in the Illinois River Valley.

It’s a branch of the Illinois State Museum and sits on the National Register of Historic Places.

Exhibits walk you through Native American life, the French colonial period and the later settler era, with the wetlands at Emiquon and Chautauqua visible in the distance from the grounds. Admission is free.

It’s the right place to end the drive, because it puts everything you just saw in context.

Plan your trip on the Illinois River Road Scenic Byway

You can pick up the byway anywhere along its 150-mile run, but if you’re starting from the north, Starved Rock and Matthiessen give you the canyon experience right away.

The byway is open year-round, and different seasons bring different rewards, from frozen waterfalls in January to peak bird migration in fall.

Some trails at Starved Rock are closed during a 2026 improvement project, so check the official website or current Illinois DNR updates before you go.

Dickson Mounds Museum is open Tuesday through Saturday, 9 a.m. to 4:30 p.m., and admission is free.
