Few wildlife encounters capture the spirit of the North Dakota Badlands quite like watching a band of free-roaming horses cross the grasslands of Theodore Roosevelt National Park. Stallions stand watch over mares and foals, young horses chase one another across open prairie, and entire bands sometimes appear along distant ridges framed by colorful badland formations.
The horses are commonly described as the wild horses of Theodore Roosevelt National Park, although the National Park Service uses the more precise term feral horses because they descend from domesticated horses. Their history is intertwined with the open-range ranching era that shaped western North Dakota during the late nineteenth and early twentieth centuries.
Today, Theodore Roosevelt National Park is one of the relatively few national parks where visitors can watch free-roaming horses living in established social groups. They are found in the park’s South Unit, where they share the landscape with bison, elk, pronghorn, mule deer, prairie dogs, coyotes, and other animals of the northern Great Plains.
The horses are also the subject of active scientific study and management. Their numbers must be balanced against the limited resources of a fenced national park, while managers are working to maintain a healthy and genetically viable population. That makes the Theodore Roosevelt horses both a remarkable visitor experience and an unusually complex conservation story.

🐎 Are the Horses Really Wild?
Visitors almost universally call them wild horses, and that description makes intuitive sense. The animals roam freely, find their own food and water, organize themselves into natural social groups, raise foals on the prairie, and are not handled as ordinary domestic horses.
Biologically and historically, however, the National Park Service classifies them as feral horses.
A feral animal is descended from domesticated ancestors but now lives without ordinary human ownership or husbandry. Horses evolved in North America millions of years ago but disappeared from the continent near the end of the Pleistocene. Modern horses were later reintroduced through European colonization.
The horses roaming Theodore Roosevelt National Park today descend from domestic stock associated with the ranching history of the northern Great Plains.
Calling them feral does not make their behavior any less fascinating. These horses have lived freely across the rugged badlands for generations and have developed strong social relationships suited to life on an open landscape.
🌾 How Horses Came to the North Dakota Badlands
Horses became deeply embedded in the culture and economy of the Great Plains after their return to North America.
Indigenous nations incorporated horses into transportation, hunting, trade, warfare, and everyday life. Later, ranchers depended heavily on horses as cattle operations spread across western North Dakota.
During the open-range era, ranchers often turned horses loose on large areas of unfenced land. Animals grazed and reproduced freely before being rounded up when needed.
The landscape that eventually became Theodore Roosevelt National Park was part of that ranching world.
By the time the park was established in the twentieth century, free-roaming horses were already present throughout portions of the Little Missouri Badlands.
🏞️ Horses When the Park Was Created
Several hundred horses were present in the area when Theodore Roosevelt National Park was developing during the 1940s and 1950s.
Early park management attempted to remove them.
As fences were constructed, ranchers participated in roundups to retrieve branded animals. A major roundup in 1954 removed large numbers of horses from what is now the South Unit.
Some horses escaped capture.
Those unclaimed animals remained behind the new park fence and continued reproducing.
For years, the National Park Service continued efforts to eliminate the remaining horses. Policy eventually changed, and in 1970 the park formally recognized a horse herd as part of the historical scene associated with the region’s open-range ranching period.
That decision laid the foundation for the population visitors see today.
🤠 Theodore Roosevelt and the Ranching Era
The horses are particularly appropriate to a park named for Theodore Roosevelt because his connection to North Dakota began during the ranching era.
Roosevelt first traveled to the Dakota Badlands in 1883 and became involved in cattle ranching along the Little Missouri River. His experiences in the region profoundly affected his views about wildlife, wilderness, land use, and conservation.
The modern park preserves landscapes closely associated with those years.
The current horse herd should not be interpreted as a herd personally owned or established by Roosevelt. Rather, the animals help represent the broader cultural landscape of the ranching period in which Roosevelt lived here.
Watching horses move across a badland ridge can therefore evoke an aspect of the landscape that would have been familiar during the open-range era.
🐴 What Do the Horses Look Like?
Theodore Roosevelt’s horses display an impressive range of colors and markings.
Visitors may encounter horses that are:
- Bay
- Black
- Chestnut
- Sorrel
- Gray
- Pinto
- Roan
- Palomino
- Buckskin
Body size and build also vary.
Genetic research indicates that the park’s horses do not represent a single isolated historical breed. Studies have identified connections with several common domestic breed types, including Quarter Horses, Paint Horses, and draft-horse ancestry.
Research has not demonstrated a clear genetic connection to Spanish colonial breeds sometimes associated with other free-roaming horse populations in the American West.
This mixed ancestry contributes to the considerable physical variety seen among the park’s bands.
🐎 Horse Bands
The horses usually travel in groups known as bands.
A typical family band contains approximately five to fifteen animals and usually includes a dominant stallion, several mares, and their offspring.
These are not random gatherings.
Horses form complex social relationships, and established bands can remain remarkably stable over time.
Individual animals recognize one another, maintain a hierarchy, communicate through body language and vocalizations, and respond collectively to threats.
Watching an entire band for an extended period often reveals far more interesting behavior than simply photographing a single horse.
👑 The Stallion
A mature stallion typically plays an important role in maintaining the band.
He watches rival males, monitors the movements of mares, and may position himself between his family group and a perceived threat.
One distinctive behavior is called snaking.
During this behavior, a stallion lowers and extends his head and neck while directing mares to move in a particular direction. From a distance, the horse’s head appears to weave low across the ground.
Stallions also establish conspicuous manure piles known as stud piles.
These scent-marking locations can occur near frequently traveled routes and are one clue that horses have been moving through an area.
🐴 Mares and the Social Structure of a Band
Although stallions may be visually conspicuous, mares play equally important roles.
A dominant or experienced mare may influence where a band travels, particularly when moving between feeding areas, water sources, and resting locations.
When horses flee from danger, a leading mare may move at the front while the stallion stays toward the rear.
This allows the stallion to keep the group together while watching potential threats.
Bands develop through relationships rather than simple physical dominance. Foals learn social behavior from adults, young horses play with one another, and mares form long-term associations within the group.
🐎 Bachelor Stallions
Not every male horse belongs to a family band.
Young males pushed out of their natal groups frequently join bachelor bands with other stallions.
These groups provide opportunities for social development and practice sparring.
As stallions mature, individuals may eventually attempt to challenge an established band stallion or attract mares to form a new family group.
Encounters between competing males can involve posturing, chasing, biting, kicking, and rearing.
Such interactions may look dramatic, but they are part of normal horse social behavior.
Visitors should never approach horses engaged in a confrontation.
🐴 Foals in Theodore Roosevelt National Park
Spring is an especially rewarding season for horse watching because new foals begin appearing alongside their mothers.
Horse gestation lasts roughly eleven months.
Newborn foals are surprisingly mobile and are capable of standing and moving shortly after birth. Within a relatively short period, they begin following the band across uneven badland terrain.
Foals remain dependent on their mothers while gradually learning which plants to eat, how to respond to other horses, and how to behave within the group’s hierarchy.
By late spring and summer, young horses can often be seen playing, running, resting, and interacting with older members of the band.
Give family groups additional space during this period.
🌾 What Do Theodore Roosevelt’s Horses Eat?
The horses are grazers, feeding largely on grasses and other vegetation growing throughout the South Unit.
The northern Great Plains may look lush during wet spring weather, but conditions can become much more demanding later in the year.
Summer heat dries the prairie.
Winter brings snow, cold, wind, and limited forage.
Periods of drought can reduce available vegetation even further.
The horses share this finite landscape with native grazing animals including bison, elk, pronghorn, and mule deer. That shared dependence on vegetation is one reason horse population management is necessary inside the fenced park.
❄️ How Do the Horses Survive Winter?
A North Dakota winter can be severe.
Temperatures may fall well below freezing, strong winds sweep across exposed ridges, and snow can cover large portions of the grassland.
The horses respond by developing thick winter coats and seeking terrain that offers some shelter from wind.
They continue grazing throughout the season, pawing or moving through snow when necessary to reach vegetation.
Their ability to survive these conditions can make the herd seem completely independent of human influence, but the park still has to manage the overall population because the horses are confined within a landscape of limited size and resources.
🌸 Horses in Spring
Spring is one of the most dynamic seasons for viewing the horses.
New vegetation begins covering the prairie, foals appear within family bands, and warming conditions increase activity across the park.
Green grass against colorful badland formations also creates beautiful photography conditions.
Roads and trails can become muddy following snowmelt or heavy rain, however.
Spring weather in western North Dakota is notoriously variable, with warm sunshine one day and snow or strong wind the next.
☀️ Horses in Summer
Summer is one of the easiest seasons to observe horse behavior.
Bands frequently graze in open areas, foals are active, and long daylight hours give visitors plenty of time to search from overlooks.
The National Park Service notes that horses are often seen grazing throughout the South Unit during summer.
Hot weather can influence their behavior.
Bands may move between feeding areas and water sources or seek terrain that provides relief from the strongest afternoon heat.
Early morning and evening are often the most comfortable times for both horses and visitors.
🍂 Horses in Fall
Fall brings cooler weather, warm low-angle light, and a changing prairie landscape.
Foals born earlier in the year are noticeably larger but still remain within their family groups.
Wildlife activity throughout Theodore Roosevelt National Park can be excellent during this season, and horse watching combines easily with searching for bison, elk, pronghorn, and bighorn sheep.
Days shorten rapidly, so photographers should plan their return before darkness.
❄️ Horses in Winter
Seeing free-roaming horses against snow-covered badlands can be extraordinary.
Winter also provides far fewer visitors and a sense of solitude difficult to find during summer.
However, road and weather conditions require careful preparation.
Snow, ice, high winds, and extreme cold can affect access within the park. Certain facilities may be limited during winter as well.
If conditions are safe, binoculars can make it possible to observe distant bands without leaving the warmth and protection of a vehicle for long periods.
👀 Best Places to See the Horses
The horses live in the South Unit of Theodore Roosevelt National Park.
Their movements vary seasonally, and bands can travel considerable distances, so no viewing location guarantees a sighting.
Current National Park Service tracking has identified several areas that are frequently used by portions of the herd.
Good places to watch include:
- Painted Canyon
- Buck Hill
- Wind Canyon area
- Southeastern South Unit
- Areas near the Talkington Trailhead
- Open country visible from portions of the scenic drive
The Southeast portion of the South Unit has been especially productive according to recent GPS tracking data.
🎨 Painted Canyon
Painted Canyon is one of the easiest places to scan large areas for horses.
The overlook provides an expansive view across layers of eroded badlands and open grassland.
Because the horses may be far away, binoculars are extremely helpful.
Even if no horses appear, Painted Canyon is worth visiting for the landscape itself. Bison, pronghorn, mule deer, birds of prey, and other wildlife may also be visible.
Spend time scanning slowly rather than looking for only a few seconds and leaving.
A distant group of horses can blend surprisingly well with the prairie.
⛰️ Buck Hill
Buck Hill provides another excellent elevated viewing position.
At approximately 2,855 feet, it is one of the highest accessible points in the South Unit.
From the top, visitors can look across broad areas of badlands and grassland.
Recent horse-tracking research has shown repeated movement in portions of the park below and around Buck Hill.
An elevated perspective provides an advantage when horses are moving through open terrain.
Bring binoculars and check distant ridgelines carefully.
🌬️ Wind Canyon
Wind Canyon is another area where bands are frequently reported.
The surrounding landscape combines open prairie, badland slopes, and views toward the Little Missouri River.
The short Wind Canyon Trail is particularly popular around sunset.
When horses are present, the combination of wildlife, badland formations, and warm evening light can create a memorable scene.
Never leave established roads or trails simply to move closer to horses.
Allow them to determine the encounter.
📍 Current Horse Movements
Theodore Roosevelt National Park has been using GPS collars to learn more about how horses move through the South Unit.
Fifteen female horses were fitted with collars during the 2024 roundup. Because horses remain in established social bands, those collared animals indirectly provide information about the movements of a much larger portion of the population.
By early 2026, the tracked bands represented the movements of roughly 70 percent of the park’s horses.
Recent data have shown substantial use of the southeastern South Unit as well as areas around Coal Vein, Buck Hill, Wind Canyon, the Little Missouri River, Jones Creek, Johnson’s Plateau, and other portions of the park.
This research is helping managers understand home ranges, habitat use, and how the herd interacts with the wider park ecosystem.
🔭 Bring Binoculars
Binoculars may be the most useful piece of equipment for viewing the horses.
These animals have excellent hearing, vision, and smell. They frequently detect people long before people realize horses are nearby.
Trying to close the distance on foot usually produces a worse wildlife encounter.
The horses may become nervous, move away, or alter their normal behavior.
Instead, use binoculars or a telephoto lens and watch from a comfortable distance.
You will often see more interesting social behavior precisely because the horses do not feel pressured by your presence.
⚠️ Never Approach the Horses
Free-roaming horses are not tame trail horses.
A stallion may defend his band, a mare may protect her foal, and any frightened horse can kick, bite, or charge.
Never:
- Feed a horse
- Touch a horse
- Walk toward a foal
- Stand between members of a band
- Chase horses for photographs
- Attempt to pet an apparently calm horse
- Block the direction horses are trying to travel
If your presence causes horses to stop feeding, raise their heads repeatedly, move away, or bunch together, increase your distance.
📸 Photographing the Horses
Theodore Roosevelt National Park offers exceptional opportunities for horse photography because the landscape provides such a distinctive backdrop.
Instead of trying to fill the frame with a horse, consider incorporating the environment.
A small band crossing a distant ridge may communicate the scale of the Badlands better than a close portrait.
Early morning and evening provide softer light and longer shadows.
Spring offers green prairie and young foals, while autumn creates warm colors and winter can transform the landscape with snow.
A telephoto lens allows close-looking photographs without disturbing the animals.
🌎 Are the Horses Native Wildlife?
The horses occupy an unusual position in the park.
They behave as free-roaming animals and are one of Theodore Roosevelt National Park’s most recognizable attractions, but they are not considered native wildlife in the same sense as bison, prairie dogs, pronghorn, or coyotes.
Modern horses were introduced to North America after the continent’s original equids had become extinct thousands of years earlier.
The National Park Service manages the Theodore Roosevelt population in connection with the park’s cultural history rather than treating it as a naturally occurring native species.
That distinction becomes important when managers consider forage, habitat, population size, and the needs of native species.
📜 Are the Horses Protected by the Wild Free-Roaming Horses and Burros Act?
No.
The Wild Free-Roaming Horses and Burros Act of 1971 applies principally to qualifying horses and burros managed on federal lands administered by the Bureau of Land Management and U.S. Forest Service.
Theodore Roosevelt National Park is administered by the National Park Service.
Its horses therefore do not receive their legal status from the 1971 Wild Horse Act.
Instead, management occurs under laws and policies governing the National Park Service and Theodore Roosevelt National Park.
This difference is one reason horse management here is not identical to wild-horse management on BLM lands elsewhere in the West.
📊 How Many Horses Live in Theodore Roosevelt National Park?
Horse numbers change through births, deaths, and management actions.
During the October 2024 roundup, park staff captured and evaluated 179 horses.
By February 2026, National Park Service tracking information indicated approximately 197 horses in the herd.
An April 2026 update referenced approximately 198 horses.
Those figures make current monitoring particularly important.
A fenced landscape can support only a finite number of large grazing animals, especially during drought or difficult winters.
Population management therefore considers horses alongside bison, elk, pronghorn, and the health of the prairie itself.
🧬 Genetics and the Herd
Maintaining adequate genetic diversity is an important part of long-term horse management.
A population that becomes too small or too isolated may experience increasing genetic problems over generations.
The National Park Service has conducted genetic research on the Theodore Roosevelt herd and continues considering genetics when evaluating future management.
The park states that its goal is to maintain a healthy, genetically viable horse population.
Recent management efforts have included gathering DNA and health data, microchipping horses for identification, and conducting population studies.
💉 Fertility Control
The National Park Service currently uses a contraceptive called GonaCon-Equine as one tool for controlling population growth.
GonaCon is an immunocontraceptive vaccine that affects reproductive processes in treated mares.
Research on its use in the Theodore Roosevelt herd began in 2009, and the park has used it as a management tool since 2020.
Some mares receive initial vaccinations followed by scheduled booster doses.
Fertility control does not eliminate the need for broader population planning, but it can reduce the rate of herd growth and potentially decrease reliance on frequent removals.
🐎 The 2024 Roundup
A major horse roundup took place in October 2024.
Park staff brought 179 horses into the South Unit corrals, where animals were assessed for health, genetics, age, sex, and other population characteristics.
Horses were microchipped to improve identification.
Fifteen mares received GPS collars so researchers could study movement and habitat use.
No horses were removed from the park during that roundup.
The information collected is now being used to develop a better understanding of the population and inform future management decisions.
📡 GPS Collars and Modern Horse Research
GPS technology is providing an unusually detailed picture of how the horses use the South Unit.
The collars record locations at regular intervals, allowing researchers to map where bands travel over weeks and months.
Because a collared mare usually remains with an established group, one collar can effectively reveal the movements of several horses.
Researchers can use those data to examine questions such as:
- Which habitats do horses use most?
- How large are their ranges?
- How often do bands approach park boundaries?
- Where do different bands overlap?
- How do seasonal conditions affect movement?
- How do horses share the landscape with bison and other grazers?
The research is helping replace assumptions with measurable information.
⚖️ The Horse Management Debate
Few wildlife-related issues at Theodore Roosevelt National Park generate more public interest than the future of the horses.
In 2023, the National Park Service released a Livestock Plan Environmental Assessment examining management options for both horses and longhorn cattle.
The proposal generated extensive public response.
In April 2024, the National Park Service terminated that planning process after considering information and public feedback received during the review.
The park subsequently continued research and monitoring rather than implementing the proposed plan.
Current work includes population studies, GPS tracking, genetic analysis, reproductive management, and development of updated management strategies.
The issue involves several goals that must be balanced: cultural history, visitor experience, horse health, genetic viability, native wildlife, vegetation, and the ecological limits of a fenced landscape.
🌱 Horses and the Prairie Ecosystem
Older descriptions sometimes portray the horses as straightforwardly beneficial grazers within Theodore Roosevelt’s ecosystem.
The reality is more complicated.
Horses consume vegetation also used by native grazing animals such as bison and elk.
Because large predators do not currently regulate the park’s major herbivore populations and fences limit movement beyond the park boundary, managers must actively consider how many large grazing animals the landscape can support.
Too many grazers can reduce vegetation, intensify competition, and leave the ecosystem less resilient during drought.
The challenge is therefore not simply preserving as many horses as possible. It is maintaining horses in a way that also protects the broader prairie ecosystem.
🦬 Horses and Bison
Seeing horses and bison on the same North Dakota prairie can evoke the history of the American West, but their ecological status is different.
Bison are native Great Plains wildlife and were historically a fundamental force shaping grassland ecosystems across North America.
Horses were reintroduced to the continent through human activity and are maintained at Theodore Roosevelt partly because of their connection to the region’s ranching history.
Both consume grasses and occupy portions of the same landscape.
Managing adequate forage for bison, horses, elk, pronghorn, and other grazers is therefore an important part of protecting the South Unit.
🦌 Other Wildlife to Watch For
Horse watching can easily become part of a broader wildlife drive.
Theodore Roosevelt National Park supports an impressive variety of mammals, including:
- American bison
- Elk
- Mule deer
- White-tailed deer
- Pronghorn
- Bighorn sheep
- Black-tailed prairie dogs
- Coyotes
- American badgers
- Bobcats
Golden eagles, prairie falcons, western meadowlarks, wild turkeys, and numerous other birds also inhabit the park.
Some of the most memorable drives are those where visitors encounter several different species rather than focusing entirely on finding the horses.
🌅 Best Time of Day to Look for Horses
Early morning and late afternoon are excellent times for horse watching.
Cooler temperatures often encourage animal activity, and low-angle sunlight makes the Badlands especially beautiful.
Midday sightings are still possible, particularly during cooler months.
More important than any fixed time is patience.
Stop at high viewpoints, scan slowly with binoculars, and watch distant openings rather than constantly driving.
The horses frequently move through areas invisible from the road before emerging again on a ridge or open grassland.
🗺️ South Unit or North Unit?
Visitors specifically hoping to see horses should focus on the South Unit.
The current free-roaming horse herd lives there.
The North Unit is excellent for bison, bighorn sheep, deer, prairie dogs, scenic overlooks, and Badlands landscapes, but it should not be the primary destination for visitors whose main goal is photographing the park’s horses.
This distinction is particularly important because Theodore Roosevelt National Park’s units are separated by considerable driving distance.
🚗 Wildlife Watching From Your Vehicle
A vehicle can be one of the best wildlife blinds in Theodore Roosevelt National Park.
Horses that would move away from someone approaching on foot may continue grazing while a respectful observer remains inside a vehicle.
If you spot horses beside the road, pull completely into a safe designated area when possible.
Do not stop in a way that blocks traffic.
Never drive off-road toward wildlife.
And remember that horses can enter the road unexpectedly, particularly when a band is moving together.
🏞️ Are the Wild Horses Worth Seeing?
Absolutely.
The horses combine wildlife watching, western history, animal behavior, landscape photography, and one of the most complicated management stories in the National Park System.
Their appeal is easy to understand.
Watching a mare and foal cross a prairie ridge or seeing a stallion gather his band against layers of North Dakota Badlands creates an image that seems inseparable from the American West.
Yet understanding the horses makes the experience even richer.
These are not untouched remnants of an ancient wild population. They are descendants of domestic horses whose history reflects ranching, changing land use, park policy, science, and evolving ideas about conservation.
That complicated history is precisely what makes them so interesting.
🌲 Final Thoughts
The free-roaming horses of Theodore Roosevelt National Park are among the most memorable animals visitors can encounter in North Dakota’s Badlands.
They live in tightly organized bands, raise foals on open prairie, survive bitter winters, and travel across a landscape shared with bison, elk, pronghorn, and other grazing animals.
Their story also reaches far beyond a picturesque wildlife sighting.
The horses are descendants of domesticated animals connected to the open-range ranching era. They are not protected under the federal Wild Free-Roaming Horses and Burros Act, and maintaining their population inside a fenced national park requires active management.
The park is currently using GPS tracking, genetics research, population monitoring, health assessments, and fertility control while working toward a long-term strategy intended to maintain a healthy, genetically viable herd alongside the park’s native wildlife and prairie ecosystem.
For visitors, the best approach is much simpler.
Bring binoculars. Explore the South Unit. Stop at Painted Canyon, Buck Hill, Wind Canyon, and other broad viewpoints. Scan the prairie patiently, and allow the horses to remain wild in behavior by never approaching, feeding, or chasing them.
When a band finally appears on a distant ridge, give yourself time to watch. The relationships between the animals—the watchful stallion, experienced mares, playful foals, and constantly shifting group—are every bit as remarkable as the Badlands surrounding them.
