Insider tip — Jerry Johnson Hot Springs Lower Pool is a wild backcountry thermal pool along the Lochsa River corridor in Idaho's Lolo National Forest, accessible via a short forest trail from Highway 12. The iron-mineral waters pool naturally in a series of riverside basins carved by centuries of geothermal flow, with the largest pool comfortably fitting a dozen bathers. The setting — old-growth cedar forest, rushing river, and mountain air — is among the most spectacular of any accessible hot spring in the American Northwest.
