## About Sulphur Creek Hot Spring

The Custer County Sulphur Creek Hot Spring lies in the Challis National Forest, 42 miles from Challis, and is reached by a hike of about a mile and a quarter from the nearest road. It shares its name with a Valley County spring on this site. Access is open, but no temperature has been recorded here, and without one it cannot be called soakable.

National forest land around 5,800 feet, mountain country with roughly 140 inches of snow most winters and yearly temperatures averaging in the low forties. Precipitation is moderate. The record holds no road name, only the distance. No USGS sample or site number is attached to this one, so there is no chemistry either.

There are no best months on file. Boundary Creek Campground, eleven or twelve miles away, is the nearest camping. Expect a hike in. The spring's temperature and condition are unrecorded, so go ready to find very little, and go in the warm months, when the snow is gone.
