About Pine Flats Hot Springs
Drive-up hot springs right along the South Fork of the Payette River near Lowman. Rock-lined pools sit steps from highway pullouts on the Banks-Lowman Highway, with thermal water seeping up at 100-120F and mixing with cold river water. You can adjust pool temps by shifting rocks to control the river flow into each basin.
