Challis Hot Springs

## Overview Challis Hot Springs is a natural geothermal spring located near the small mountain town of Challis in Custer County, Idaho. Situated at approximately 44.52°N, 114.17°W, the springs sit along the Salmon River corridor in central Idaho's rugged high-desert landscape. Challis Hot Springs has long been a popular destination for locals and travelers alike, offering naturally heated mineral water in a scenic setting surrounded by the peaks and valleys of the Salmon River Mountains. The hot springs have been developed into a commercial facility featuring outdoor soaking pools fed by the geothermal source. The area around Challis is rich in mining history and outdoor recreation, and the hot springs have historically served as a gathering place and respite for visitors exploring this remote stretch of Idaho. The geothermal activity in this region is linked to the same volcanic and tectonic forces that shape much of central Idaho's dramatic terrain. ## Directions 1.
