Boiling River

Boiling River is a unique natural attraction in the northern part of Yellowstone National Park, where a hot spring and a cold river merge together, creating a perfect spot to relax in a natural hot tub.

The hot spring water flows out of the ground at temperatures of up to 140 degrees Fahrenheit, but as it enters the Gardner River, it cools down, creating a comfortable and safe temperature to soak in.

Wade into the water and find the perfect spot where the hot spring and cold river water mix. The experience is truly unique, as you can feel the temperature change as you move closer to the source of the hot spring water.

Be advised that swimming or soaking in the Boiling River is only allowed in designated areas for safety reasons. The Boiling River may be closed during high water or extreme weather conditions, so it's always a good idea to check with park rangers before making the trip.
