The rule here

This is a thermal feature to see, not a place to get in the water. Yellowstone National Park puts it this way:

“On the other end of the temperature spectrum, the water in park hot springs often reaches the boiling point. For this reason, and to protect the park's unusual thermal environments, soaking in hot springs is prohibited.”
