Location
0 miles from Helena West Side, MT

The spring emerges on the west side of Helena in the broad valley of Prickly Pear Creek, flanked by the foothills of the Continental Divide to the west and the Big Belt Mountains to the east. At roughly 4,000 feet, the surrounding landscape blends dry grassland with scattered ponderosa pine. Annual snowfall averages 47 inches and precipitation stays modest at 18 inches, producing semi-arid conditions despite the mountain-valley setting. The nearby Missouri River drainage shapes the regional hydrology.

Visit year-round, though winter soaking is especially rewarding when air temperatures drop well below freezing. The roadside location means no special gear or hiking is required. Moose Creek Cabin, a reservable Forest Service rental 14 km west, provides a rustic overnight option. Helena's services are minutes away. Expect snow from November through March.

History of Broadwater (Helena) Hot Springs

The springs have long been associated with Helena's development as the state capital. The name references the Broadwater Hotel and Natatorium, a lavish resort built in the 1880s by Colonel Charles Broadwater. That original structure was demolished in 1946 after decades of decline. Subsequent commercial operations have used the thermal water in various configurations. The site remains one of the few urban hot springs facilities in Montana.
