Badlands National Park

The heart of Badlands is the eroded rock itself, a broken wall of buttes and pinnacles that geologists call a badlands formation, meaning land so cut up by water that it is hard to travel across. The colored stripes you see are layers of ancient mud, ash, and sand laid down over millions of years, each band a different age. Rain and snowmelt cut into this soft rock fast, so the shapes are always shifting. In a landscape this dry, that steady carving is a slow kind of motion you can almost watch.

All around the rock lies the prairie, and it is just as important as the spires. The park protects one of the largest mixed-grass prairies remaining anywhere, a sea of grass where bison graze, pronghorn sprint, and bighorn sheep pick their way along the ledges. Prairie dogs pop up from their burrows in noisy colonies, and the black-footed ferret, the most endangered land mammal in North America, was brought back to this prairie in 1994. The grass and the stone together make Badlands feel wild and wide open.

There is one more story hidden in the rock: fossils. Badlands holds some of the world's richest fossil beds from the Oligocene epoch, a time roughly 23 to 34 million years ago. Ancient horses no bigger than dogs, saber-toothed cats, rhino relatives, and other long-gone mammals died here and turned to stone, and new bones weather out of the hills all the time. The park is a working place for scientists, and along the Badlands Loop Road and its overlooks you are never far from a slice of that deep past.

• Northeast Entrance, off Interstate 90 at Exit 131 near Cactus Flat and Wall, is open year-round and is the most common way in. It leads quickly to the Big Badlands Overlook and the start of the Badlands Loop Road.
• Interior Entrance, off SD-377 near the small town of Interior, is open year-round and sits near the Ben Reifel Visitor Center on the south side of the park.
• Pinnacles Entrance, off SD-240 on the Badlands Loop Road near Wall, is open year-round and puts you close to the Pinnacles Overlook and the turnoff toward the Sage Creek bison country.
• Most travelers reach the park from Interstate 90. Wall is right at the northeast door, Rapid City is about an hour to the west, and the whole park is easy to fold into a drive across South Dakota or a loop through the Black Hills.

• Drive the Badlands Loop Road (SD-240), a scenic road with more than a dozen overlooks and short boardwalk trails, where the whole maze of spires opens up beside you and wildlife often walks near the pavement.
• Stop at the Ben Reifel Visitor Center for geology and paleontology exhibits, and in summer watch real scientists prepare fossils behind glass in the fossil lab.
• Hike the Notch Trail, a roughly 1.5-mile round trip through a slot canyon and up a log ladder to a ledge with big views. It has real drop-offs and gets slick when wet, so it is not for young children or after rain.
• Watch for wildlife along the road: bison, pronghorn, bighorn sheep, and whole towns of prairie dogs are often visible without leaving your car.
• Head out to Sage Creek Basin in the remote northwest corner, reached by an unpaved rim road, for some of the best bison viewing in the park.

Long before it was a park, this land was and still is part of the world of the Lakota people. The Oglala Lakota, whose Pine Ridge Reservation borders and overlaps the park to the south, have deep ties to this ground. In their language the place is often called Mako Sica, meaning bad land, a name that speaks to how hard it is to cross rather than to any lack of worth. The prairie fed the buffalo, and the buffalo fed the people, and the stone and grass hold generations of history and meaning.

The park's South Unit lies within the Pine Ridge Reservation and is co-managed with the Oglala Sioux Tribe. Within it is a high tableland known as the Stronghold, a place of great importance to the Lakota. In 1890 it was one of the last places where people gathered for the Ghost Dance, a spiritual movement of hope in a time of loss, in the same winter that ended in the tragedy at Wounded Knee just to the south. These are sacred and sorrowful places, and the park works with the tribe to tell their stories with care and respect.

Fossil hunters and scientists were drawn to the eroded hills as early as the 1840s, and word of the rich bone beds spread through the young field of paleontology. Homesteaders later tried to farm the tough prairie around the rock with mixed success. To protect both the fossils and the striking scenery, the area was set aside as Badlands National Monument in 1939. Through those early years the Civilian Conservation Corps, a Depression-era work program, built roads, trails, and structures that shaped how visitors see the park today.

In 1978 the monument was expanded and redesignated as Badlands National Park, and the South Unit within Pine Ridge was added under the shared care of the National Park Service and the Oglala Sioux Tribe. Today the park protects the fossil beds, the mixed-grass prairie, and the wildlife that lives on it, from returning bison herds to the rare black-footed ferret, while honoring its role as Lakota homeland.

• Badlands is one of the richest fossil beds on Earth for its age. The rock holds the bones of ancient mammals from the Oligocene epoch, roughly 23 to 34 million years old, and new fossils weather out of the hills every year.
• The colorful stripes in the rock are real layers of ancient time. Each band of red, tan, or gray is mud, ash, or soil from a different period, stacked up over tens of millions of years.
• The whole formation is slowly wearing away. The soft rock erodes about an inch a year on average, which means the spires you see are not permanent and the whole landscape is quietly changing.
• The park helped save the most endangered land mammal in North America. The black-footed ferret, once thought to be extinct, was reintroduced to the Badlands prairie in 1994.
• Bison roam free here again. Once nearly wiped out across the plains, they now range across the park's grasslands, especially in the Sage Creek area.
• The park's South Unit sits within the Pine Ridge Reservation and is co-managed with the Oglala Sioux Tribe, one of the few national park lands managed this way.
• The name comes from a hard truth about the land. Both the Lakota name Mako Sica and the French trappers' term mauvaises terres meant 'bad lands,' a nod to how difficult it is to travel through.
• The night skies are famously dark. Far from big city lights, the park is a favorite for stargazing, and rangers host night sky programs in summer.

• An entrance fee applies (per vehicle, good for seven days), and interagency annual passes are accepted; check the park website for current rates.
• The Badlands Loop Road (SD-240) is the main scenic drive, lined with overlooks and short trails. Allow at least an hour for the drive itself, longer if you stop and walk.
• Start at the Ben Reifel Visitor Center for geology and paleontology exhibits and to plan the rest of your day.
• The Notch Trail is a rewarding short hike through a slot canyon and up a log ladder, but skip it when the clay is wet and slick, and keep an eye on children near the drop-offs.
• Watch for wildlife from the road, including bison, pronghorn, bighorn sheep, and prairie dogs, and always keep a safe distance.

Yes. Badlands charges a per-vehicle entrance fee that is good for seven days, and interagency annual passes are accepted. Check the National Park Service website for the current rate before you go.

The Badlands Loop Road (SD-240) is the classic way to experience the park. It winds for miles between the Wall and Interior entrances with more than a dozen overlooks, including Pinnacles Overlook and Big Badlands Overlook, plus short boardwalk trails. The drive takes about an hour without stops, longer if you pull over often, and you can often see wildlife right from the road.

No. Badlands holds some of the richest fossil beds in the world, but it is illegal to collect, dig up, or remove any fossil, rock, or plant from a national park. Look, photograph, and leave everything where it is. If you spot a fossil, note the location and tell a ranger, since your find could help scientists. The rule keeps this deep history in place for everyone.

Spring and fall are the most comfortable seasons, with milder temperatures and softer light. Summer brings the most services and ranger programs but can be very hot, and winter is quiet and cold with a stark beauty. Whenever you come, mornings and evenings bring out the best colors in the rock.

Summer days can be extremely hot, and there is very little shade among the rocks and grass. Sudden thunderstorms can also roll in fast on the prairie. Carry plenty of water, wear a hat and sunscreen, keep an eye on the sky, and get off high or exposed ground if a storm approaches. Cool mornings are the easiest time for hiking.

Watch all wildlife from a safe distance and never approach or feed it. Bison in particular are large, fast, and dangerous, and people are hurt every year getting too close. Stay in or near your vehicle when bison are by the road, keep your distance from bighorn sheep and prairie dogs, and use a zoom lens or binoculars instead of stepping closer for a photo.

You can see the main overlooks and drive the Badlands Loop Road in a half day. To add a hike or two, spend time at the visitor center, and drive out toward the Sage Creek bison area, give the park a full day. An overnight lets you catch both sunset and the famously dark night skies.

Pets are allowed in developed areas, campgrounds, parking lots, and along roads, but not on the trails or in the backcountry. Keep them leashed, bring plenty of water, and never leave a pet in a hot vehicle. Check the park website for the current pet rules before you visit.

There is lodging and camping inside the park near the Cedar Pass area, plus a more primitive campground out at Sage Creek. Just outside the park, the towns of Wall and Interior offer more rooms and services, and Rapid City about an hour west has the widest choice. Book ahead in summer, when the region is busy.

The park's South Unit lies within the Pine Ridge Reservation and is co-managed with the Oglala Sioux Tribe. Within it is the Stronghold, a place of deep importance to the Lakota and tied to the 1890 Ghost Dance and the events at Wounded Knee. These are sacred and sorrowful places, so visit with respect and follow tribal and park guidance in the South Unit.
