Owen Cabin Hot Spring is a five-mile hike from Loon Creek Road in the Challis National Forest, Custer County, something like twenty-seven miles from Challis. The water at the source runs hot, well above soaking temperature. The access entry says open. This is the kind of spring you plan a day or an overnight around.

Location

High mountain country, with a winter snowpack around eight feet and moderate precipitation. Five miles on foot each way from the road. The Forest Service holds the land and it carries the plain National Forest designation. Nothing on file describes the route or the source itself. Carry everything, since there is no development on record at the source.

Best months on record run December through February. That is a strange answer for a spring behind five miles of trail in snow country, so read it as the soak being best in cold air and plan the trip for whenever the route is passable. Custer #1 Campground is eighteen miles away, the only camping on record. Nothing about a fee. Test before entering; the outlet is hot enough to burn.

Heat Below
117 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 70% 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.
