Montana’s historic Boulder Hot Springs Inn and Spa is located almost mid-way between Butte and Helena just off Interstate 15. 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.
Our Inn offers a combination of comfortable, inviting, elegant and luxurious B&B rooms and suites for guests who want the best that a healing, homelike atmosphere has to offer, and guest rooms for our more budget-minded guests.
Our greatest attraction is our 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. In addition, the Inn & Spa has spacious and gracious meeting rooms and facilities for special events and occasions of all kinds.
