White Sulphur Springs
White Sulphur Springs flows at 136 degrees Fahrenheit in the town that bears its name, the county seat of Meagher County, Montana. USGS measurements record 48 degrees Celsius with near-neutral pH of 6.9. The water carries 480 mg/L sodium and 300 mg/L sulfate, reflecting deep geothermal circulation. It sits just 16.1 meters from South Central Avenue.
At 5,040 feet elevation, the spring occupies the broad Smith River valley of central Montana, surrounded by the Big Belt, Castle, and Little Belt mountain ranges. The valley floor is open grassland and irrigated hay fields, with cottonwood-lined creek bottoms. Annual precipitation averages 17.5 inches with 56.3 inches of snow. The Smith River, a prized float-fishing waterway, drains northward through the valley a short distance from town.
The Crow and other Indigenous peoples are known to have used these thermal waters before Euro-American contact. The town was established in 1866 when James Brewer built the first bathhouse. A grand resort hotel, The Springs, operated in the late 1800s and drew visitors from across the territory. Today, the springs feed a small commercial spa facility in town, continuing a bathing tradition spanning more than 150 years.
The spring is accessible year-round in the center of town. A commercial spa operates on-site with soaking tubs fed by the thermal water; check hours and fees before visiting. Summers bring warm days and cool nights, while winters are cold with frequent sub-zero stretches. The Smith River float season runs May through July and pairs well with a soak. Thompson Guard Station, a reservable Forest Service cabin, sits 23.8 km away.

Overview Thompson Guard Station is located in the Big Belt Mountain Range in Helena National Forest. Historical records indicate that the guard station was built in 1954 for rangers in the district, but it may have been used as a cookhouse for a Civilian Conservation Corps camp prior to that date. In later years, engineering and road maintenance crews used the cabin as lodging. Today, the cabin is a rustic getaway for guests seeking relaxation and recreation in west-central Montana. It is...
