Bozeman Hot Springs, Natural mineral spring in Gallatin Valley, Montana, US.

Bozeman Hot Springs is a bathing facility in Gallatin County, Montana, with twelve indoor and outdoor pools whose water ranges from 59 to 106 degrees Fahrenheit (15 to 41 degrees Celsius). The water flows through without chemical treatment. The outdoor pool has a pale grey concrete rim, and in winter a thin layer of white vapour drifts over its light blue surface, with snow-covered evergreens and a metal fence beyond the far edge.

The location began as a small natural pool in the late 1800s and gradually developed into a modern bathing facility. Over time, the site expanded to serve both local residents and visitors exploring the Montana region.

The springs sit at 1,444 metres in the Gallatin Valley, 11.6 km west of Bozeman, where the land is farmland and the nearby slopes rise toward Wheeler Mountain. The water emerges naturally and flows through the pools without chemical treatment, so bathers share untreated mineral water. Snow-covered evergreens and a metal fence stand beyond the outdoor pool in winter.

The springs lie about 11.6 km west of Bozeman, in Gallatin County at 1,444 m above sea level. The surrounding land is mostly farmland, with Wheeler Mountain rising 18.5 km to the south. The climate is continental: July averages 22 °C, January −12 °C.

The facility operates using a flow-through system that keeps the water clean without chemical additives. This approach preserves the natural minerals in the water that give the springs their relaxing properties.
