Trinity Hot Springs

Trinity Hot Springs lies deep in the Salmon River Mountains of central Idaho, within or near the Frank Church–River of No Return Wilderness — one of the largest roadless areas in the contiguous United States. The springs produce geothermal water at around 47°C that pools in natural rock basins alongside a mountain creek. The rugged approach by trail or packstock rewards visitors with an extraordinary wilderness setting where the silence is broken only by birdsong and rushing water.
