Two tourists have sparked widespread outrage after they were seen walking dangerously close to Grand Prismatic Spring in Yellowstone National Park while taking selfies near the scalding thermal waters.
The incident happened Sunday evening, July 20, 2026, when visitors at the popular Yellowstone attraction spotted two women walking across the fragile microbial mats surrounding the spring, an area that is strictly off-limits to park visitors.
Tanya Saueressig of Livingston, Montana, was visiting Yellowstone when she witnessed the incident from the Grand Prismatic boardwalk. She said she initially could not believe what she was seeing.
“I stopped in my tracks and was like, ‘Is that people? That can’t be people. Nobody’s that dumb,’” Saueressig said.
She explained that the moment quickly turned from concern to frustration as she watched the visitors move closer to the spring while taking photos.
Grand Prismatic Spring is one of Yellowstone’s most famous natural features, but it is also one of the park’s most dangerous locations. The water temperature in the spring can reach between 145 and 188 degrees Fahrenheit, creating a potentially deadly environment for anyone who gets too close.
Saueressig said she feared the women could fall into the hot spring and that spectators could witness a tragedy.
“I started getting scared because I thought they were going to fall in and get really, really hurt,” she said.
Beyond the danger to themselves, officials and conservation advocates have warned that walking on the surrounding areas can permanently damage Yellowstone’s delicate microbial mats, which create the spring’s famous colors.
Thermal trespassing in Yellowstone is illegal and can result in fines, possible jail time, and bans from the park. Despite warning signs, barriers, and designated viewing areas, some visitors continue to ignore safety rules in search of photos or unique experiences.
Videos of the incident quickly spread online, drawing criticism from thousands of people who accused the tourists of putting themselves at risk and damaging one of the park’s most protected natural features.
As of the latest reports, Yellowstone officials have not confirmed whether the individuals involved have been identified or whether any enforcement action has been taken.
The incident has renewed discussions about visitor safety, responsible tourism, and the challenges park officials face in protecting Yellowstone’s fragile landscapes from reckless behavior.
While many visitors enjoy the park responsibly, officials continue to remind tourists that thermal areas can be unpredictable and dangerous, and that staying on designated trails is essential for both personal safety and environmental protection.
