About Pine Flat Hot Springs

A secluded riverside soak along the South Fork of the Boise River near the tiny hamlet of Featherville. Hot water seeps into rock-lined pools at the river's edge, allowing bathers to regulate temperature by adjusting the cold river flow. The pine-forested setting and lack of development create a true backcountry feel.
