The Basics

In collecting all of the mineral rich water, which has been naturally heated by the earth, the Firehole River can run 15 degrees warmer than surrounding rivers and lakes—with the steam that’s often emitted from the surface being one of the reasons for its name. That’s why park visitors come to swim in the Firehole River swimming hole, where water temperatures hover at a moderate 75°F (23.8°C). Tourists can also drive through Firehole Canyon to the 40-foot (12-meter) Firehole Falls, the site of another popular summer swimming hole. Many guided tours of Yellowstone National Park include a visit to the Firehole River area and its colorful Fountain Paint Pot situated nearby.

When to Get There

If you want to swim in the Firehole River, visit on a warm summer day. The rest of the year offers opportunity to observe the steamy waters of the river, but it’s too cold to swim. The Firehole River swimming area sometimes closes due to high water levels from snowmelt or summer rainstorms.
