Badlands National Park: Eroded Buttes of South Dakota
Updated: 2 hours ago
Badlands National Park hits you the moment the grass ends. One minute you are driving across flat prairie, and the next the ground drops into a maze of striped buttes, spires and gullies.
Badlands National Park Intro
Badlands National Park is a wide-open stretch of South Dakota where wind and water have been cutting soft rock into pieces for a very long time. The result is stark, steep and colorful, and it sits right beside one of the largest protected mixed-grass prairies in the country.
My trip into this maze of eroded buttes began with the silence that met me when I stepped out of the car. The wind moved through the grass, and nothing else did. Tall spires, jagged ridges and deep gullies stretched out in every direction, a landscape that looked nothing like the grassland I had just driven across.
The Badlands give up their story in layers. The bands of rock run red, orange, yellow and gray, and each one is a different chapter of sediment or volcanic ash laid down and cut away over millions of years.
At dusk I climbed to a rim and watched the light go. Shadows stretched across the folds, the colors deepened to rust and rose, and after dark the stars came out thick over the prairie. The only sound was wind. It is easy to see why people drive out of their way for this place.
Badlands Fast Facts
Badlands is where the mixed-grass prairie breaks apart into buttes, spires and gullies cut from soft, banded rock.
Location: Southwestern South Dakota, about 75 miles east of Rapid City
Established: National monument in 1939, and a national park since 1978
Size: About 244,000 acres, split into a North Unit and a South Unit
Signature rock: Layers of sediment and volcanic ash, eroding up to about an inch a year
Fossils: One of the richest fossil beds of ancient mammals in the world, around 30 million years old
Wilderness: The Sage Creek Wilderness, home to bison and reintroduced black-footed ferrets
Introduction and Geography
The park is a patchwork of two very different landscapes. The first is the eroded buttes and pinnacles of the Badlands Wall, a long ridge that runs across the North Unit. The second is the prairie that surrounds and floods around it, miles of grass that carries on to every horizon.
The rock here is soft. Rain, frost and meltwater strip it down grain by grain, and every storm sends a little more of the walls into the washes. That is why the formations look raw and sharp rather than rounded, and why the shape of the place keeps changing. The color bands tell you what was laid down when: pale layers of ash, darker bands of old soil, and yellow and tan mud and sand from ancient floodplains and seas.
The South Unit is the quieter, more remote half. It is rougher, has fewer services, and is managed together with the Oglala Sioux Tribe, as it lies within the Pine Ridge Reservation.
Top Attractions in Badlands
Most visitors start with the Badlands Loop Road, a scenic drive that runs along the Wall with a string of pull-offs. Each overlook gives a different angle on the same striped country, and the light changes the whole look every hour. Give it a slow half day: stop at the overlooks, walk a trail or two, and come back to the best ones when the sun is low.
Short Trails Worth Your Time
The trails near the Door and Window parking area are the easiest way to get off the road and onto the dirt.
Door Trail: a short boardwalk that leads to a gap in the Wall and a view across the formations.
Window Trail: a very short walk to an overlook through a notch in the rock.
Fossil Exhibit Trail: a short, easy walk with signs showing the fossils found in this country.
Notch Trail: a steeper outing that ends with a ladder climb and a wide view of the White River Valley. Skip it in wet weather or if heights bother you.
Tip: Leave the Pavement
Marked trails are only a start. In much of the park you can walk off-trail through the formations, but the clay turns to slick, sticky mud when wet, and the footing on steep slopes is poor. Take it slowly, watch for loose rock and turn around when the weather turns.
Overlooks and Backroads
The Yellow Mounds Overlook shows the paler, mustard-colored hills at their best, especially in low light. Along the Wall, the stops are close together, so you can compare the same rock under changing sun and cloud without much driving.
Out on Sage Creek Rim Road, the pavement ends and the prairie opens up. This is the place to look for bison and prairie dogs, and it feels a long way from the loop road crowds. Gravel roads turn greasy after rain, so check conditions first and keep your speed down.
Best Times to Visit
Summer is the busiest season, and it is hot, exposed and prone to sudden thunderstorms. Spring and fall are cooler and quieter, and the light is softer on the buttes. Winter brings cold, wind and snow, along with solitude, but some roads and services can close or become difficult.
Late spring brings green grass and wildflowers on the prairie, and the rock colors look richer against the green. Fall dries the grass to gold, thins the crowds and gives long, low light on the Wall. In winter the formations can sit under a dusting of snow, but wind chill is serious and the gravel roads may not be passable.
Whatever the season, go early or late. Sunrise and sunset bring out the reds and pinks in the rock, and the heat of the day is easier to avoid. Check the National Park Service website for current road status, weather alerts and seasonal conditions before you set out.
Wildlife and Nature
Badlands is much more than rock. The grasslands support one of the most diverse prairie communities in the park system.
Bison: herds graze the open prairie, especially around Sage Creek. Keep your distance, as they are large and unpredictable.
Bighorn sheep: sure-footed climbers that pick their way across the crumbling slopes and often show up near the roads.
Prairie dogs: their towns are busy and noisy, and the animals are easy to watch from a safe distance.
Black-footed ferrets: one of the continent's rarest mammals, reintroduced here and rarely seen.
Birds and reptiles: meadowlarks, hawks and rattlesnakes all live in the grass and rock, so watch where you put your hands and feet.
Rattlesnakes are part of the prairie, so stay on open ground and give them room. Fossils are part of the story too. Ancient rhinos, early horses and saber-toothed cats once roamed this country.
Prairie and Night Sky
The grass is a mix of native species that hold the thin soil together, and in places a living crust of biological soil crust helps bind it. Step on it and you break what took years to form, so stay on trail where marked. Away from town lights, the night sky is dark enough to show the Milky Way, and a clear evening on the rim is worth the wait.
Gear and Leave No Trace
Carry plenty of water per person, wear sun protection, and pack layers for sudden wind. Stay on trail where marked, pack out all trash, give wildlife room and leave rocks, fossils and plants where they are.
History and Culture of the Badlands
The Lakota called this country mako sica, "land bad," and French trappers had their own name for it: bad lands to cross. People have hunted here for more than 10,000 years, and the Lakota still have deep roots in the land. The park's South Unit lies within the Pine Ridge Reservation and is managed together with the Oglala Sioux Tribe; Stronghold Table there was a site of the Ghost Dance in 1890.
From Monument to National Park
Fossil hunters came in the 1840s and have not stopped since. South Dakota Senator Peter Norbeck pushed for years to protect the formations, and they became Badlands National Monument in 1939. It was made a national park in 1978.
Fossil Rule
If you find a fossil, leave it where it is, take a photo and report it at the Ben Reifel Visitor Center. Some of the park's best finds have come from visitors who did just that.
Plan Your Visit
Badlands is hot, open and short on shade in summer, so carry more water than you think you need and hike early. Check the National Park Service website for current entrance fees, road conditions and campground details before you go.
A field-tested loadout is simple: sturdy boots with grip, a wide-brimmed hat, sun protection, layers, a headlamp for after-dark stargazing, and more water per person than seems sensible. Stop at the Ben Reifel Visitor Center first for maps, ranger advice and current conditions.
