Stay at a Historical and Haunted Hotel near Yellowstone National Park with Natural Hot Springs!

Updated: Sep 28, 2020

As the name suggests, the Boulder Hot Springs Inn is centred around the mineral-laden, pure geothermal waters, which are used in the indoor plunges, the outdoor swimming pool, the natural mineral steam rooms, the showers, and also to heat the entire building.

Just between Butte and Helena, Montana is a little secret tucked away that is close to Yellowstone National Park.

In the 1980s it was slated for demolition, as it had fallen into a great deal of disrepair. However, an enterprising woman named Anne Wilson Schaef, with 11 other investors poured their money into the hotel, as well as their hearts, and today, the hotel stands as a healing retreat in the middle of Montana. But a lot of motorists, road trippers and visitors to Yellowstone do not even know this secret exists.

Montana’s historic Boulder Hot Springs Inn, Spa, and Retreat Center is indeed a secret. It rests in the midst of southwest Montana’s spectacular beauty of snow-capped mountains and lush valleys. The Inn & Spa sits on almost 300 acres of pristine meadows, wetlands and forest. The air is pure and the sounds you hear are those of nature. The Inn is backed by Deerlodge National Forest, home to bears, moose, elk, deer, fox, antelope and coyotes.

The Inn offers a combination of comfortable, inviting, elegant and luxurious B&B rooms and suites for guests who want the best that a healing, historic atmosphere can offer.

The onsite kitchen specializes in healthy, home-cooked, and delicious gourmet, locally sourced organic food.

The Hot Plunge Pools

The hot geothermal mineral water is piped into our indoor plunges where it is mixed with natural cool water and maintained at a temperature of between 103-106°F.

  • The women’s plunge has a hot pool maintained between 103-106°F and a cool pool which is usually under 70°F.

  • The men’s side has a hot pool maintained at 103-106°F and no cold pool.

Both hot pools are “continuous flow”, completely changing the water in the plunges every four hours. In addition, the plunges are cleaned nearly every night. You will find the plunges to be some of the cleanest and most natural (no harsh chemicals added!) you will ever experience. Both mens and womens sides of the bath house have dressing rooms, toilets, places to rest, and steam rooms. The steam rooms are heated by natural mineral geothermal water running through perforated pipes, so the steam baths are natural mineral steam which is very healing and healthy.

The Outdoor Pool

The outdoor swimming pool is a graduated depth pool with a floating line dividing the shallower from the deeper end. The deck surrounding the pool has chairs and tables for relaxing. A heated sidewalk connects the pool and the bath house. The cool crisp evenings in Montana and the contrast of falling snow and hot mineral water make the outdoor pool a popular and fun-filled place to hang out, do your laps, have a romantic evening, or just have fun with the family.

  • The swimming pool uses the geothermal mineral water from our springs cooled by our natural well water.

  • The water temperature is maintained at approximately 96-100°F.

The Ghosts of the Boulder Hot Springs Inn

The hotel is haunted by the ghost of Simone, a former prostitute who is said to have been murdered on site by a Butte mining executive. Simone is said to be a non-threatening ghost and has been protective of the hotel and its guests.

Some guests who've stayed at the bed-and-breakfast nestled in the foothills of the Beaverhead Deerlodge National Forest say they have encountered an unexplained strong order of perfume, heard footsteps in an empty hallway and even seen a woman in a white gown looking out the windows.

Some guests said they heard children running up and down the halls. They didn't know this, but the St. Joseph's Orphanage was destroyed (in the 1935 Helena earthquake) and those children stayed at the hotel.

Others say they fell an energy in the old hallways and rooms that they cannot explain.
