When a Yellowstone Bison Tosses a Tourist into the Air: What Every Visitor Needs to Know

It was a scene straight out of a movie: a man standing near a grazing bison herd in Yellowstone National Park suddenly found himself airborne, his body flung a few feet before he hit the ground with a thud. The startled visitor, who prefers to remain anonymous, escaped with only bruises, but the incident has sent a clear signal to anyone who thinks wildlife can be approached like a postcard.

According to park rangers, the man had stepped far closer than the recommended 25‑yard buffer—well within striking distance of the massive animals that can weigh up to two thousand pounds and sprint up to 35 miles per hour. "Bison are not a petting zoo," said a Yellowstone spokesperson. "They are powerful, wild creatures, and they react instinctively when they feel threatened or crowded."

The episode isn’t the first of its kind. In the past decade, there have been at least a dozen documented bison encounters that resulted in injuries, ranging from minor bruises to serious trampling. In 2023, a hiker was knocked unconscious after a sudden bison charge, highlighting just how unpredictable these animals can be.

Rangers are now urging visitors to treat bison sightings with the same respect you’d give to a charging bull. Stay on designated trails, keep a wide berth—preferably more than 25 yards—and never try to feed or approach them, even if they seem docile. Dogs must be leashed at all times, as a barking or running pet can trigger a defensive response from a herd.

For those hoping to get a good photo, the park recommends using zoom lenses from a safe distance or visiting established wildlife viewing platforms, where you can watch the herd’s dramatic movements without putting yourself in harm’s way. If a bison begins to move toward you, back away slowly; do not run, as sudden movement can be interpreted as a chase.

Yellowstone officials say they are reviewing the incident and will consider additional signage or barriers in the area where the encounter occurred. In the meantime, they ask anyone who witnesses a bison acting aggressively to report it immediately, so rangers can intervene before a situation escalates.

Bottom line: the awe‑inspiring presence of bison is one of Yellowstone’s greatest draws, but it also demands a healthy dose of caution. Enjoy the wildlife, but remember that these animals belong in the wild—not in our personal space.
