Seeing a 2,000-pound bison up close is the main reason visitors drive the 18-mile Wildlife Loop. The park is home to about 1,350 free-roaming American Bison. Because these animals move freely across the road and grasslands, following specific park rules protects both you and the herd.
How close can you get to the bison in Custer State Park?
You must maintain a distance of at least 100 yards from bison and elk.
This rule applies whenever you are outside a vehicle or hiking near the loop. Bison are large and easily agitated by humans getting too close. If a bison moves toward you, back away slowly to maintain that 100-yard buffer.
Can you get out of your car near the bison?
No, you must stay inside your vehicle if bison are within 100 yards.
Bison frequently block the Wildlife Loop Road during wildlife jams. When this happens, keep your windows up if animals are right next to the car. Do not step out onto the road or the shoulder to take photos.
Are bison dangerous to visitors?
Yes, bison are dangerous and deceptively fast.
Despite their massive size and slow grazing behavior, they can sprint much faster than a human. Never approach them on foot or try to pose for pictures near them. They can charge without warning if they feel threatened.
Where should you stop to look at the bison?
Pull completely off the road and to the right of the white line.
Do not stop your car in the middle of the road unless animals are actively blocking your path. Drive slowly on the loop. The maximum speed limit is 25 mph, and you must be prepared for sudden stops.
Can you feed the bison or other animals?
Feeding park wildlife is strictly prohibited.
This rule includes bison, elk, pronghorns, and prairie dogs. Feeding wild animals makes them aggressive and reliant on human food. While visitors unofficially feed the feral begging burros, park management discourages feeding all wildlife entirely.
How do you safely photograph the herd?
Take photos from inside your car or use a telephoto lens from a distance.
Pack binoculars and a camera with a good zoom lens for safe viewing. This allows you to capture detailed shots without violating the 100-yard rule. For closer views off the main road, consider a guided Buffalo Safari Jeep Tour.
Questions travellers ask
Do bison block the Wildlife Loop Road?
Yes, bison traffic jams are common on the 18-mile loop. You must wait patiently inside your car until the herd moves off the pavement.
Are pets allowed near the bison?
Pets must be on a leash no longer than 10 feet at all times. Do not let your dog bark at or approach the bison, as this can provoke the herd.
Do you have to pay to drive the loop?
Yes, all vehicles need a Temporary Park Entrance License. This costs $20 and covers 1 to 7 days of access to the park. Vehicle Entrance Fee
