Less than 4% of America’s great tallgrass prairie survives and most of it is in Kansas

America’s rarest grassland runs through the Flint Hills

Kansas Highway 177 cuts 47 miles through a landscape that once covered 170 million acres across North America.

Today, less than four percent of that original tallgrass prairie survives, and most of it is right here in the Flint Hills.

The two-lane road rolls through Morris, Chase and Butler counties, passing small towns rooted in the Santa Fe Trail, a courthouse older than most American institutions, and a bison herd that came back from nothing.

If you tune your radio to 1680 AM, narrated history plays the whole way down.

Rocky soil and fire kept the plows away for centuries

The Flint Hills formed from sediment left behind by a shallow sea about 280 million years ago.

Layers of limestone and shale sit so close to the surface that crop farming was never practical here, so the prairie was never broken.

Cattle ranching moved in instead, and without meaning to, ranchers saved the grassland. Every spring, usually in late March and April, they burn it.

Native Americans first used fire to chase bison toward fresh green shoots. Without those annual burns, invasive trees would take over in about 30 years.

The native grasses survive because their roots reach 12 feet down.

Council Grove marks the start of a long road west

At the northern end of the byway, Council Grove carries the weight of American history on every block.

In 1825, U.S. commissioners signed a treaty with the Osage under a large oak tree here, opening passage along the Santa Fe Trail.

After that, this town became the last place to stock up before heading west into hundreds of miles of open country. Main Street still follows the original trail path.

More than 25 historic sites dot the town, many of them marked with National Park Service signage.

The Kaw people left their name on Kansas itself

The Kaw Mission, built in 1851 from native stone, served as a school for 30 Kaw boys before the tribe was forced out of the region entirely. The Kaw, also called the Kanza people, gave Kansas its name.

They were relocated to Council Grove in 1846, then pushed to Oklahoma in the 1870s. The Kansas Historical Society runs the building as a state historic site today.

Nearby, the original Post Office Oak trunk sits under shelter, a 300-year-old bur oak that served as an informal mail drop for trail travelers between 1825 and 1847.

The only national park built around a single ecosystem

Tallgrass Prairie National Preserve covers nearly 11,000 acres along the byway north of Strong City. It is the only unit in the entire National Park System dedicated to the tallgrass prairie, and it gets in for free.

The land runs through a partnership between the National Park Service, which owns about 32 acres, and The Nature Conservancy, which owns the rest.

The Kansas Sampler Foundation named it one of the eight Wonders of Kansas in 2008. You can walk 40 miles of maintained trails through it without crossing a fence or a road.

Thirteen bison started a herd that now numbers near 90

In 2009, 13 bison arrived at the preserve from Wind Cave National Park in South Dakota, the first bison to roam this land in more than a century.

Those animals were picked for their genetic diversity and clean health records. The herd has since grown to roughly 85 to 90 animals.

Bison do more than look good on the horizon. Their grazing spreads seeds, keeps grass height in check and pushes plant variety higher across the prairie.

Your best shot at spotting them is a hike through the Windmill Pasture area.

Ranch buildings and trails wind through the preserve

The Spring Hill Ranch house, built in 1881 from local limestone, sits on the preserve grounds in Second Empire style, open for tours. A three-story limestone barn stands nearby.

About a mile north of the visitor center, you’ll find the Lower Fox Creek Schoolhouse, a one-room building from the 1880s.

The most popular hike is the Windmill Pasture Hilltop Trail, about three miles with wide views and regular bison sightings.

During summer months, the preserve has run free ranger-led van tours, though you’ll want to check current availability before you go.

A French-style courthouse built before Kansas was 15 years old

Halfway down the byway, Cottonwood Falls and Strong City sit together along the Cottonwood River. The Chase County Courthouse in Cottonwood Falls went up in 1873, making it the oldest operating courthouse in Kansas.

Architect John G. Haskell, who later worked on the Kansas State Capitol in Topeka, designed it in French Renaissance style with a red mansard roof that climbs 113 feet.

Inside, a three-story spiral staircase was cut from walnut trees pulled from the Cottonwood River. The building is on the National Register of Historic Places and open for self-guided tours on weekdays.

Pull off at Schrumpf Hill for the full prairie view

Three miles south of Cottonwood Falls, the Schrumpf Hill Scenic Overlook gives you the broadest read on what this landscape actually is. Paved walkways lead to interpretive panels on the plants and animals around you.

The rolling hills stretch in every direction, broken only by native grass and the occasional stone fence.

Historic stone walls and working farmsteads line the road south of here, some of them still running cattle the same way they did 100 years ago.

Come at sunrise or sunset and the whole landscape shifts into something else.

More than 500 plant species and a prairie chicken that stomps

The Flint Hills carry over 500 species of plants, but the most dramatic wildlife moment happens before most people are awake.

Each spring, male greater prairie chickens gather at dawn, inflate orange air sacs on their necks and stomp the ground in a mating display called booming.

Deer, wild turkey, quail and bald eagles all move through this corridor as well.

Two side trips worth taking: the Flint Hills National Wildlife Refuge off Highway 50 from Strong City, and Chase County State Lake west of Cottonwood Falls, both solid spots for birdwatching.

The Prairie Chicken Capital sits at the end of the road

Cassoday closes out the byway at the southern end in Butler County.

About 113 people lived there as of the 2020 census, and the town holds the title of Prairie Chicken Capital of the World. The Cassoday Historical Museum sits inside the old railroad depot.

From the mid-1920s to the late 1950s, more cattle moved through this 25-mile stretch of railroad than almost anywhere else on the Atchison, Topeka and Santa Fe line.

On the first Sunday of every month from March through October, the Cassoday Bike Run draws motorcycle riders from across the region.

The drive takes an hour, but give it a day or two

You can cover all 47 miles in about 55 minutes without stopping, but one stop will turn into five, and you’ll want the afternoon for it. The byway runs through every season differently.

Spring brings wildflowers and prescribed burns lighting the horizon at dusk. Summer fills the hills with tall green grass and blooming prairie.

Fall turns everything gold and rust. Winter strips the land down to stark open views that go on for miles.

Most of the surrounding land is private ranch, so stay on marked trails and leave the fences alone.
