Yellowstone National Park’s most popular soaking area. A 6-foot-wide stream of hot water plunges over travertine rocks into a 50-yard-long band of thermal soaking pools along the Gardner River. The largest discharge of thermal water in Yellowstone, Boiling River is also the park’s most popular soaking location, at times accommodating 150 people in the warm water. The attractiveness of this soak is no doubt attributable to its easy access from the North Entrance Road, its beautiful location, and the awesome soaking opportunities. Geologists suspect that the Boiling River’s 100-yard channel of 140-degree-F hot water is the underground flow from Mammoth Hot Springs, some 2 miles to the south. The 6-foot-wide stream pours over travertine ledges into the swift-flowing Gardner River, where it mixes with cold river water. The water level in the Gardner River determines the temperature of your soak. You may encounter a blast of hot water on your back, while at the same time your toes are shivering in the icy river water, but most bathers eventually find just the right spot for their thermal tastes. Primitive.
