Snorting bison push their way through the sagebrush heading north on Utah’s Antelope Island State Park. But they’re not alone. Whistling and shouting horsemen follow, men and women trained and instructed in the fine art and science of wrangling 2,000-pound animals. Ready to join the roundup? Read on. Whether you’re doing the herding or watching from a safe distance you’ll want to join the adventure.
Antelope Island’s annual bison round-up in late October takes place in relative obscurity on a stunning landscape from another geologic era making this event a wonderful opportunity to view the Utah bison population close-up and in a relatively natural habitat. Watching an authentic roundup with real cowboys and cowgirls is like being on the set of an old west movie or transported to a distant era—yet it’s only 25 miles northwest of Salt Lake City. And it’s even closer from our home base of Valley View RV Resort in Layton.
The sage scented serenity of the island slowly recedes as spectators and riders arrive for the big day. Spectators rush to find a good spot to watch in anxious anticipation of the arrival of the parade of bison. The bison are followed by the riders as they negotiate their way from the southern area of the Island to the north holding pens. The somewhat slow but forced pace ensures the safety of all humans and wildlife for this spectacular event. Spectators are always delighted with the number of good locations to stop and follow the herd as it makes its way north.

Ride with the herd
Experience the thrill of working alongside these iconic animals
The park asks people to sign up (for the roundup) if they want to be an aggressive rider or if they want to be a leisurely rider. Typically, about 100 people will want to go on the leisurely ride and be close to the bison but not engaged. They take the other 200 and break them into teams and call them a left flank, right flank, and center.
About 50 people are allowed to ride with the core group of riders. These are the guys and gals that know what they are doing, have done this year after year, know what the bison are going to do, know when it’s dangerous, when it’s safe, when they need to ride harder on one side or harder on the other.
It’s something to see cowboys (and cowgirls) chasing 700 bison around with dust flying everywhere and them snorting and hollerin’. The goal is to get all the bison into the corral safely and not have any of the riders injured in the process.
That’s the thing about bison. They’re big animals. The park staff is frequently asked if the bison are tame. They stress to visitors these are wild animals and caution people not to approach them. Signs are posted throughout the park and the best course of action is to keep a safe distance. Bison can run up to 30 miles per hour which is much faster than humans. They don’t have to run around obstacles (brush), they rumble through things.
They bring in every bison except for the mature bulls. Any bull three years old or over, they leave out. They don’t really need them. They’re not going to sell them and they don’t need to be vaccinated again. They’re basically breeder bulls and they’re hard to herd and they’re really ornery when you get them with a bunch of other bison. Once corralled the bison will have a thorough health check the following weekend, which is also a sight to behold. Two weeks later some will be auctioned off to the public. In 2024, approximately 290 bison were sold to high bidders.

Viewer information

Hosted each year at Antelope Island State Park, the Bison Roundup is a primary tool utilized to help ensure the continued health of one of the nation’s largest and oldest public bison herds. To help people better understand how the bison herd is managed, you can visit Antelope Island State Park the day of the event and experience it first-hand.
Registration is not required for the viewing public. Come witness a true Western experience as hundreds of horseback riders round up nearly 700 bison from around the Island and move them north into the holding corrals. Riders begin at 9:00 am from Fielding Garr Ranch and move the herd north.
Visitors can watch this event from the east side road as well as witnessing the final push into the corrals from a viewing area at White Rock Bay. At the viewing area in White Rock Bay there will be food for purchase (cash only), educational information, and activities. Bring a camp chair or blanket for seating. Typically in the past the Roundup is completed between noon and 3:00 pm but these are wild animals and we can’t predict how long the roundup will take.

What happens at the roundup?
Riders spread out to locate and group bison
There are two phases to the Bison Roundup. The first phase which will take place on Saturday, October 25 2025 is where horse riders round up and push the smaller groups of bison into one large herd. The riders then drive the bison into a holding corral where they rest for about a week. This rest period helps reduce the animals’ stress levels and allows them to relax, making them more cooperative during the second phase. Public riders are welcome to assist in this phase.
This first phase is a popular event every year and attendees include both local spectators and visitors from around the world.
The second phase begins the week following the roundup, October 28-30, 2025. During the Working of the Bison, the animals are sorted and separated one at a time to receive their vaccinations. They receive individual health screenings that include checks for pregnancies, parasites, and health issues.
The bison are also given a small RFID tag, which serves as a permanent ID and links them to their computer records that store their health information. Once the bison are checked, they are either released back onto the island or kept in the corral where they are later sold in a public auction. Free public tours and media opportunities are available all three days of this phase.

A spectator sport
Watching one of the nation’s oldest public bison herds in motion
Jolene Rose was a wildlife biologist on staff at Antelope Island. She refers to the 50 or 60 mature bulls left out of the roundup as members of the “grumpy old men’s club.” They can be seen in small groups scattered throughout the island.
Rose has a healthy respect for the bison. During her early years on the job they conducted the bison roundup using vehicles and helicopters. The last time they used vehicles and helicopters she watched a full-grown bull put its horns through the door of a full-size Ford Bronco and almost put the vehicle up on two wheels. He apparently had enough of being pushed around. This practice stressed the bison and was abandoned for the current roundup procedure on horseback.

Where do bison live
Bison thrive in grasslands, prairies, and open woodlands
Custer State Park in South Dakota and Antelope Island State Park are about the only places where people can actually experience a public bison roundup first hand. Though Yellowstone National Park is home to one of the nation’s most famous free-roaming herds of bison, they are not rounded up.
For those interested in participating but not riding, spectators are welcome and encouraged. There are two ways to participate. Individuals may view the roundup from inside or outside their vehicle along the miles of roads that parallel the driven bison. Visitors can find plenty of areas on the island where they can catch all the action from a safe distance.

It all leads to this
Get there early, soak in the moment, and witness the wild in action!
The state park offers a number of recreational events throughout the season and has plenty of other wildlife available for viewing. Hikers, cyclists, and photographers are likely to see the island’s namesake pronghorn antelope and mule deer but the park is also home to bighorn sheep, coyotes, bobcats, badgers, porcupines, and numerous birds of prey. But the bison roundup is the crème de la crème and a truly distinct Antelope Island experience.
You’re talking about a lake (The Great Salt Lake) just out the park’s back door that’s about the size of Rhode Island—that’s a huge draw in of itself. Then you couple the island with it and it’s almost a combination that can’t lose. It’s truly like no other place in the world.
The island is so peaceful and yet so wild. When you visit it, it changes your heart. I think that’s the draw. It changes your heart.
This relatively obscure local event can be a great opportunity for a family wanting to see a real roundup of a wild bison herd.

Worth Pondering…
O give me a home where the buffaloes roam
Where the deer and the antelope play
Where seldom is heard a discouraging word
And the skies are not cloudy all day Home, home on the range
Where the deer and the antelope play
Where seldom is heard a discouraging word
And the skies are not cloudy all day.
—Brewester M. Higley, 1872
