Theodore Roosevelt National Park in western North Dakota is one of the easiest places in the US to see big prairie wildlife from your car. Bison graze beside the road, feral horses roam the South Unit, prairie dogs bark from their towns, and if you time it right, elk and bighorn sheep appear on the buttes.
This guide covers which animals live where, when to look, the best drives, and the practical details that changed in 2025 and 2026. For the rest of the state, see my North Dakota travel guide.

Which Animals Live Where
The two main units are roughly 70 miles apart, and they do not share the same wildlife. This is the most useful thing to know before you plan.

|---|---|---|
| Bison | Yes | Yes |
| Feral horses | Yes | No |
| Elk | Yes | Rare |
| Bighorn sheep | No | Yes, on steep cliffs |
| Longhorn cattle | No | Yes, small demonstration herd |
| Prairie dogs | Three large towns along the road | Only via a hike |
| Mule and white-tailed deer | Yes | Yes |
Bison
Bison are the park’s headliners, and most visitors see them from the road. The park reintroduced them in 1956, and today it manages herds of roughly 200 to 500 in the South Unit and 100 to 300 in the North Unit, moving surplus animals to Tribes and other herds during periodic roundups.
- Where to look: Anywhere along the South Unit Scenic Loop Drive and the North Unit Scenic Drive, where the NPS says they are often visible at all hours. They also wander near the Painted Canyon rest area off I-94.
- Behavior: They look sleepy, but bison can sprint fast and charge with little warning. Summer is breeding season, and bulls are more aggressive.
- Safety: Stay at least 25 yards away, including on trails. Rangers at the visitor centers can tell you about recent sightings.
Feral Horses
The South Unit is home to a herd of feral horses, descended from domestic stock and maintained by the park as a cultural resource. An NPS collar study in early 2026 referred to about 198 horses in the park. They live in bands, usually a stallion with mares and foals.
- Where to look: From the Scenic Loop Drive and from I-94. The NPS names Painted Canyon, Buck Hill, and Wind Canyon as good lookouts, plus the southeast corner of the park near the Talkington trailhead (I-94 exit 36).
- Not in the North Unit: If horses are your priority, focus on the South Unit.
- Management: Horse numbers and management have been a public debate for several years. The park updates its horse page regularly, so check it if you want the latest.
Prairie Dogs
Black-tailed prairie dogs are the park’s most entertaining residents. They live in colonies called towns, post sentries on their mounds, and “bark” warnings when a hawk or coyote shows up. They are a keystone species, supporting predators like badgers, coyotes, and raptors.
- South Unit: The scenic road passes through three large prairie dog towns, so you can watch from a pullout.
- North Unit: No towns are visible from the road. The nearest is about a one-mile hike from the Caprock Coulee parking area.
- Tip: Watch from your car or the road edge. Do not feed them or step onto the mounds.
Elk
Elk vanished from the North Dakota badlands by the late 1800s. The park reintroduced them on March 13, 1985, and the population has grown since. They are among the park’s most elusive large animals.
- Where to look: The South Unit. Elk are rare in the North Unit. The NPS suggests scanning the butte tops to the west from Wind Canyon Overlook at sunrise or sunset, and the Buck Hill area.
- When: Dawn and dusk. During the day they hide in shady juniper and hardwood draws.
- Seasonal highlight: The rut runs from September into the fall, when bulls bugle loudly. Calves are usually born in early June.
Bighorn Sheep and Longhorns
Two North Unit specialties are easy to miss if you only visit Medora.
- Bighorn sheep: Reintroduced to the badlands starting in 1956, they live on steep terrain along the Little Missouri River in the North Unit. Watch cliff edges near the scenic drive, and bring binoculars. Good optics beat squinting at distant ledges, especially with eyes that have a few decades on them.
- Longhorn cattle: A small demonstration herd lives in the North Unit as a nod to the area’s ranching history, the era when Roosevelt ran cattle here. Look around mile marker two of the scenic drive.
Deer, Pronghorn, and Smaller Mammals
- Mule deer: More common than white-tails, often seen in open areas along the road between dusk and dawn. Look for big ears and a bouncing gait.
- White-tailed deer: Prefer wooded river bottoms, campgrounds, and picnic areas in the early morning and evening.
- Pronghorn: More common in the surrounding Little Missouri National Grassland, but small groups sometimes enter the park.
- Coyotes: The most commonly seen predator. Listen for them after dark, or look near prairie dog towns at twilight.
- Badgers: Most often seen near prairie dog towns at dawn or dusk.
- Bobcats: Rare. The NPS says only a few are seen each summer.
- Beavers: Look along the Little Missouri River and creeks in the North Unit.
There are no wolves or grizzly bears in the park, and mountain lions only occasionally pass through.
Birds and Reptiles
More than 185 bird species have been recorded in the park, and most are migratory. Year-round residents include golden eagles, wild turkeys, and great horned owls. Spring and fall bring migrants, including big flocks of sandhill cranes. In summer, the western meadowlark, North Dakota’s state bird, sings from the grasslands.
- Golden eagles: Scan the sky over the Little Missouri floodplain and at the North Unit’s River Bend Overlook.
- Songbirds: The campgrounds near the river are productive in the morning and evening, especially where trees meet grassland.
- Snakes: Bullsnakes and racers are the most common. The prairie rattlesnake is the park’s only venomous species, so watch your step in tall grass.
Best Drives for Wildlife Viewing
- South Unit Scenic Loop Drive (36 miles): The full loop reopened in November 2025 after a multi-year, roughly $51 million repair of a section damaged by landslides in 2019. Plan at least two hours. This is your best bet for bison, horses, elk, and prairie dogs.
- North Unit Scenic Drive (14 miles each way): Out and back, about 28 miles round trip, with at least 1 hour 15 minutes of driving. Bison are common, and River Bend Overlook is the signature view. It is quieter than the South Unit.
- Painted Canyon (I-94): A visitor center and rest area with a rim walk and frequent bison. It is not a park entrance; the scenic drive starts 7 miles west in Medora.
Parts of both drives can close in winter for snow and ice. Check the park’s road status before you go.
Best Times of Day and Year
- Dawn and dusk: The best hours for elk, deer, coyotes, and badgers. Bison are visible most of the day.
- Spring: Bison calves and new foals in the horse bands, plus migrating birds.
- Summer: The busiest season, with the bison rut and long evenings. Drive early to beat the heat.
- Fall: Elk bugling in September, fall color in the draws, and quieter roads.
- Winter: Bison look dramatic against the snow, but services are limited and roads can close.
Wildlife Viewing Safety and Rules
- Keep 25 yards away from all wildlife: That includes the horses and prairie dogs. If an animal moves away as you approach, you are too close.
- Stay in your car when animals block the road: Bison often walk the pavement. Wait for them to move.
- No calls or spotlights: Using wildlife calls or spotlights is illegal in the park.
- Keep pets in your vehicle: Pets can stress wildlife, and wildlife can injure pets.
- Drive slowly: Deer, elk, pronghorn, and horses are rarely alone. If one crosses, look for more.
Practical Tips for Your Visit
- Pay by card or online: The park went cashless on May 1, 2026. If you only have cash, the park says two local third-party vendors sell passes.
- Reserve campsites: Since May 2026, all sites at Cottonwood (South Unit) and Juniper (North Unit) campgrounds need a Recreation.gov reservation.
- Plan for no services in the North Unit: The nearest town is Watford City, about 15 miles north. Fill up before you go.
- Base in Medora for the South Unit: The town has lodging, food, and the new Theodore Roosevelt Presidential Library, which opened July 4, 2026. Adult tickets are $26, hours vary by season, and timed tickets are recommended.

Suggested Two to Three Day Itinerary
- Day 1: Drive the South Unit Scenic Loop in the late afternoon, stopping at the prairie dog towns, then watch for elk from Wind Canyon Overlook at sunset.
- Day 2: Sunrise drive for horses and elk, then Painted Canyon and the Presidential Library in Medora.
- Day 3: Drive about an hour and a half north to the North Unit for bison, bighorn sheep, longhorns, and the view from River Bend Overlook.

Final Thoughts
Theodore Roosevelt National Park delivers wildlife with very little effort, as long as you know which unit holds what. Come at dawn or dusk, bring binoculars, pay by card, and keep your 25 yards. The bison will do the rest.
