Video shows tourists breaking Yellowstone rules at Grand Prismatic
Updated July 21, 2026, 5:11 p.m. ET Visitors are supposed to stick to designated walkways around thermal features at Yellowstone National Park. It’s not just for their own safety or the protection of the park’s famed, fragile resources. It’s also the law. That didn’t seem to stop two recent tourists at Yellowstone’s largest hot spring. Tanya Saueressig of Livingston, Montana, captured video of them walking on the colorful bacterial mats of the park’s iconic Grand Prismatic Spring on July 18. “I did this double take like, this can’t be real … yep, that’s actually people out there,” she told USA TODAY. “And then I started getting scared for them because people have fallen into the thermal features.”
