Stanley Hot Springs is a series of thermal springs in the Clearwater National Forest, reached by hiking close to three miles from Wilderness Gateway Loop A. The listing puts it in Lewis County with Kamiah the nearest town at 37 miles. Wikipedia places it inside the Selway-Bitterroot Wilderness in Idaho County. The water is hot, around 120 degrees. Access is open.

Location

About 3,600 feet, and wet. Annual precipitation tops fifty inches and snowfall averages over 200 inches, so this is damp mountain country with long winters. Forest Service land throughout, National Forest designation, nothing recorded about a fee. The nearest road is a campground loop, and the hike in from it is roughly three miles.

Wilderness Gateway campground sits about three miles off, the same distance as the road. December through February are on file as best months, though with the snow that falls here that will be a snow trek. Hot water at 120 degrees can scald with time. If Wikipedia's placement inside the wilderness is right, wilderness regulations apply.

Heat Below
79 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 13% 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.
