Nestled in Peace Valley in Southwest Montana, the historic Boulder Hot Springs Inn & Spa sits on nearly 300 acres of pristine meadows, wetlands and forest. Our biggest attraction is our mineral-laden, geothermal waters coming from deep within the earth. We offer day soaks and overnight accommodations, hot plunges, steam rooms, massages and a hot outdoor pool with a beautiful vista.

The indoor pool temperature is kept at 104 to 106 degrees Fahrenheit, while the 20-foot by 60-foot outdoor pool is kept at 96 to 100 degrees.
