Every fall on Antelope Island, the ground shakes and the dust swirls as hundreds of bison thunder across the open plain. Riders on horseback steer the herd toward the corrals, reviving a piece of Utah’s wild frontier. If you’re planning a trip to Utah, timing your visit around the Annual Bison Roundup on Antelope Island isn’t just a great idea, it’s a must see. Below is your complete spectator guide: when it happens, how to get there, what to expect, safety tips, and how to make the most of your experience.

Key Dates & Structure of the Roundup

In 2025, the main push (when riders drive bison from the southern half of the island toward the corrals) is scheduled for Saturday, October 25.

The Roundup is organized in phases:

• Phase 1: The Push (Oct. 25) – This phase moves smaller groups of bison into a larger herd and towards corrals.
  • The best viewing area, now called The Roundup Rendezvous, is the event festival area and best place to see the final push into the corrals. It is located at White Rock Bay (north side of island). At the viewing area there will be food for purchase, vendor booths, educational information and activities from 10:00am-3:00pm. Bring a camp chair or blanket for seating.
    
  • On past years, spectators have noted that the herd’s arrival at the corrals tends to happen midday to early afternoon (12:00-3:00 pm), though timings are approximate because, well, they are animals.
    
• Phase 2: Herd Work (Oct. 28-30) – Once the bison are corralled, they rest for several days to reduce stress. Free public tours and media opportunities may be available; contact the park for more details.
• Phase 3: Working the Herd – In subsequent days, the animals are examined, weighed, vaccinated, scanned, and tested.
• Phase 4: Auction (Nov. 5) – The final phase is the auction of excess animals.
  
  

 “The Roundup Rendezvous is a festival complete with food trucks, educational and retail booths, games and fun for all!  This portion of the event is open from 10:00-3:00pm.”

🚙 What to Bring: Spectator Essentials

🌿 Why It Matters: Conservation, Culture & Connection

• The Bison Roundup is not a spectacle purely for tourists, it’s crucial wildlife management. The island’s bison herd is semi-free ranging, and because there are no natural predators, officials must manage herd numbers to maintain ecological balance.
• Through the roundup, park staff collect health data (blood tests, vaccinations, scanning, weights) to monitor disease, genetics, and overall health.
• Surplus animals are auctioned, with revenue supporting park and wildlife programs.
• The roundup is also a lived tradition: riders, volunteers, visitors all take part in a western heritage event that connects people with nature and the deep history of bison in this land.

📌 Final Reminders

• Check the official Antelope Island Bison Roundup page for updates.
• Please follow all signage on the island the day of the event.
• Be patient and flexible, animals are wild, weather may shift, and plans may change.
