Boiling River Hot Springs
• 45th Parallel Sign | Gardiner, MT
The Boiling River Hot Springs lie just inside Yellowstone National Park between Gardiner and the park village of Mammoth Hot Springs. Formed by the scorching, underground Boiling River flowing into the cold waters of the Gardiner River, the heated pools are popular with locals and tourists alike and, although the pools are unadvertised, they can be visited by hundreds of tourists a day in peak season.
