Out past Cascade in Valley County, Bull Creek Hot Springs has a hole in its record: the survey calls the water hot and gives no temperature at all. Nobody can tell you from this page if it soaks. The file marks access as open. The water surfaces a few hundred feet from the Bull Creek trail, which the record treats as the nearest road, at something over five thousand feet within Boise National Forest boundaries.

Location

Reaching it means a short walk once the driving ends. The country is high and the winters are serious, close to fifteen feet of snow in an average year, and this corner of the forest is wet, close to forty inches a year. Peace Valley Campground is the nearest developed camping, around five miles off. What the walk itself is like is not written down anywhere.

No season is rated best for this spring. Take the temperature gap seriously: the only chemistry on hand is a 1979 sample, strongly alkaline, and it says nothing about heat beyond the single word hot. Go expecting to look before you decide anything. Peace Valley is the campground to aim for, and the Forest Service is the landlord.

Heat Below
123 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 73% 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.
