About Bruneau Hot Spring

Bruneau Hot Spring is a natural hot spring in Owyhee County, Idaho, about 23 miles south of Mountain Home, ID. The nearest large city is Boise, ID, roughly 61 miles away as the crow flies.

The temperature at the source has been recorded at 106°F (41°C). That puts it in the "very hot" range. Hotter than a hot tub. Enter slowly, keep soaks short and get out if you feel dizzy.
