Nat Soo Pah Warm Spring comes out of BLM ground in Twin Falls County within a tenth of a mile of Hoppers Gulch Road, about sixteen miles from Twin Falls. The water is a little under body temperature, the kind you can stay in for a long while without overheating. Public access is open through the Burley Field Office. No fee or development shows up in the record.

Location

Dry, low-relief country at around forty-six hundred feet. Precipitation is scant, with a few feet of snow, so the snow is rarely the obstacle it is in the mountains. The walk from Hoppers Gulch Road is very short, barely off the road. The BLM owns the land and there is no designation on file beyond ordinary public land.

Winter is the listed best season. Mild water and cold air suit each other, and the approach is easy enough to do in any month. Lower Penstemon is the nearest campground on file, about fifteen miles out. Nothing is recorded about a fee. The water is gentle enough that no caution is needed on temperature.

Heat Below
92 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.
