Hot Creek Warm Spring is a Boise National Forest source in Valley County, about thirty miles from McCall as the crow flies. Water comes out at roughly body temperature, soaking warm without being hot, and the land is open to the public. The closest camping is the Johnson Creek Guard Station, only a couple of miles off.

Location

Johnson Creek Road is the nearest road, and the spring is a bit over half a mile from it, so count on a walk. The elevation is mid-mountain, around fifty-five hundred feet. Snowfall here is heavy, roughly fourteen feet a year, and the area gets a fair amount of rain besides. National Forest ground, no added designation.

Midwinter shows up as the best window in our climate data, which is odd for a place with this much snow, so read that as the driest months and plan the approach with snow in mind. The guard station sits a couple of miles off. The only water sample we have dates to 1958. No fee on record.

History of Hot Creek Warm Spring

Heat Below
93 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 35% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
