Soak up the Montana sunshine in our outdoor mineral hot pool!

Filled with geothermal mineral water from our natural hot springs and cooled with well water, the pool is maintained at a comfortable 96–100°F, making it a relaxing place to unwind in any season.

With a graduated depth and comfortable deck seating, it’s easy to settle in and enjoy the view. Our heated walkway connecting the outdoor pool to the bath house is especially nice in cooler seasons.

Come take a soak and stay awhile at Boulder Hot Springs!

In exciting news from Boulder Hot Springs, we have started restoring the barn which has been a beloved part of Boulder Hot Springs and the Boulder Community for so many years.

We have been searching for a while to find options for how to save the barn and have finally found some help and guidance through one of our guests, a restoration specialist from Butte. Our priority is putting a new roof on the structure to ensure that it does not deteriorate further and the building is protected in the future. We are also looking at ways to stabilize the foundation and flooring to ensure the stability of the building.

We always put our profits back into the facility and projects like this in order to protect and steward this place and its history and we welcome contributions from the community to support our efforts. You can reach us at 406-225-4339 to make a contribution or come out in person to soak in our pools and see the progress on the restoration!

You may notice some exceptionally hard-working pollinators at work on the beautiful flowers in full bloom near the outdoor pool at Boulder Hot Springs.

Bombus rufocinctus is the scientific name for the red-belted bumble bees who are generally considered to be quite calm and peaceful unless directly bothered.
