White Sulphur Hot Springs

White Sulphur Hot Springs sits at the heart of White Sulphur Springs, a small Montana town in the Smith River Valley, flanked by the Big Belt and Little Belt Mountains of the central Rockies. The town literally takes its name from the geothermal springs that have defined it since the 19th century, making this resort-style facility one of Montana's most historically grounded thermal destinations.

The sulfurous water flows at 35 °C with an acidic pH of 6.5, producing a water with a recognizable mineral character — the distinctive sulfurous note that has marked this valley's springs for generations of Montana residents and travelers. Bathing at White Sulphur carries an almost narrative quality: the surrounding mountains, the weathered character of the town, and the long local history of geothermal use all converge in the experience of sinking into water that has defined this place for well over a century.
