The Boiling River Trailhead has a small parking area, a single restroom which also serves as a changing room for swimmers heading to the Boiling River Hot Spring. The wearing of a swimsuit is required at Boiling River.
From this trailhead, Boiling River Hot Springs is a short, mostly level .5-mile upstream walk along the Gardner River. The hot spring keeps this part of the river warm which offers a chance to relax, unwind, and soak in a natural outdoor hot pool. Until the 1980’s the hot spring was relatively unknown except by locals. Evening “hot potting” parties were common and often included adult beverages and nudity. When the Boiling River Trail Project was created, new rules were instituted that prohibited nudity, alcohol, and nighttime swimming. This is one of only a few legal swimming areas in Yellowstone and can provide an enjoyable soak in hydrothermal waters.
