Right on the Salmon River outside Challis, this is a simple, welcome pool stop on the long haul up US 93. The big pool is 100 by 30 feet and kept near 96 degrees in summer and 98 to 100 in winter; the hot pool sits around 105. The odorless water bubbles up through the pools themselves at nearly 3 cubic feet per second. RV and tent sites make it an easy summer overnight. In winter the campground closes, the pools go 18-and-over and they shut Mondays and Tuesdays. Admission prices aren't posted, so call ahead on 208-879-4442.
