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.
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.
