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 in the heart of central Idaho's rugged landscape, this hot spring has long been a popular destination for visitors seeking a warm soak surrounded by stunning high-desert scenery. The springs sit along the Salmon River corridor, an area renowned for its dramatic canyon landscapes, abundant wildlife, and rich history tied to both indigenous peoples and early Western settlers. Challis Hot Springs has historically operated as a developed hot springs facility, offering visitors a more accessible and comfortable soaking experience compared to many of Idaho's remote backcountry hot springs. The geothermally heated water emerges naturally from the earth, a product of the region's deep volcanic geology and the extensive fault systems that characterize central Idaho's Basin and Range terrain. The area around Challis is well known for its concentration of natural hot springs, owing to the geologically active nature of the region. The town of Challis itself serves as a gateway to some of Idaho's most spectacular wilderness areas, including the Frank Church–River of No Return Wilderness and the Salmon River — often called the "River of No Return."
