# Tourists Filmed Walking Off Boardwalk at Yellowstone’s Grand Prismatic Spring

Two Yellowstone National Park visitors were filmed walking across a restricted thermal area near Grand Prismatic Spring, an act that could place them at risk of serious injury and potential federal charges.

Video recorded Sunday, July 19, appears to show the two visitors standing near the edge of the massive hot spring while taking photographs. [Cowboy State Daily reported](https://cowboystatedaily.com/2026/07/20/tourists-again-illegally-walk-on-dangerous-grand-prismatic-spring-in-yellowstone/) that the incident occurred at Grand Prismatic Spring in the park’s Midway Geyser Basin.

It was not immediately clear if park rangers identified the visitors or issued citations.

## Yellowstone Requires Visitors to Stay on Boardwalks

Leaving the boardwalk in a Yellowstone thermal area is not merely a violation of park guidance. It can be a federal offense.

Under [36 CFR § 7.13(j)](https://www.ecfr.gov/current/title-36/chapter-I/part-7/section-7.13), foot travel in Yellowstone’s thermal areas must remain confined to maintained and officially marked boardwalks or trails.

The National Park Service warns visitors that the ground around hot springs and geysers may consist of a thin crust covering boiling water or scalding mud. Conditions constantly change, making it impossible to determine where the ground is safe enough to support a person.

Grand Prismatic Spring is the largest hot spring in the United States and one of Yellowstone’s best-known attractions. The colorful bands surrounding the spring are created partly by heat-loving microorganisms known as thermophiles.

Walking on those areas can damage the microbial mats that give the spring its distinctive colors. The National Park Service specifically tells visitors not to scratch, touch or disturb the hydrothermal mats.

## A Photograph Can Come With Jail Time

Visitors caught leaving Yellowstone’s thermal boardwalks have faced fines, jail sentences and bans from the park.

In November 2024, [Joseph Aita of Colorado Springs was sentenced to seven days in jail](https://www.kktv.com/2024/11/08/colorado-springs-man-banned-yellowstone-national-park/) after walking off a designated trail in the Canary Spring thermal area at Mammoth Hot Springs. The U.S. Attorney’s Office said Aita entered the protected area with another adult and two children.

Viktor Pyshniuk, a 21-year-old Washington man, also received[seven days in jail after leaving a boardwal](https://www.justice.gov/usao-wy/pr/washington-man-receives-jail-sentence-thermal-trespass-and-closure-violation-yellowstone)k near Steamboat Geyser in 2024. Prosecutors said he crossed a fence and walked up a hillside to take a photograph closer to the geyser.

Actor [Pierce Brosnan pleaded guilty in a separate Yellowstone case](https://www.foxnews.com/entertainment/pierce-brosnan-pleads-guilty-yellowstone-case-admits-stepped-off-trail-national-park-thermal-area?msockid=1f8ca4a852926de8228ab33a537e6ce2) after posting photographs of himself standing in a thermal area at Mammoth Hot Springs. He was fined $500 and ordered to pay $1,000 to the Yellowstone Forever Geological Fund.

More recently, the Justice Department [announced in April 2026](https://www.justice.gov/usao-wy/pr/texas-man-receives-jail-time-walking-designated-boardwalk-thermal-area-yellowstone) that a Texas man received jail time after pleading guilty to walking off a designated Yellowstone boardwalk in a thermal area.

## Yellowstone’s Hot Springs Can Be Deadly

Yellowstone officials repeatedly warn that thermal areas can cause severe burns or death.

More than 20 people have died after entering or falling into the park’s hot springs, according to the National Park Service. Boiling water may be located immediately below the surface, even where the ground appears firm.

The park’s guidance for Grand Prismatic Spring tells visitors to remain on boardwalks, supervise children, avoid running or pushing and never disturb the hydrothermal mats.

Those rules protect visitors as well as one of the park’s most sensitive natural environments.

A photograph may take only a few seconds, but leaving the boardwalk could result in permanent injuries, criminal charges or damage that lasts far longer.
