Hot Springs SD | USA South Dakota

Hot Springs is an incorporated city and the seat of Fall River County, situated at the southern edge of the Black Hills. Known as the "Southern Gateway to the Black Hills," it is defined by its warm mineral springs, its high-density collection of Romanesque sandstone architecture, and its status as a world-class paleontological research site.

Historical Timeline

Inhabited by the Lakota Sioux and Cheyenne, who called the springs "Minnekahta" (Warm Water) and used them for medicinal and spiritual purposes. Founded in 1879 by European settlers attracted by the curative power of the geothermal waters. A critical historical event occurred in 1907 with the completion of the Battle Mountain Sanitarium (now the VA Medical Center), a massive sandstone structure that established Hot Springs as a premier healthcare center for veterans. In the late 20th century, the city gained international scientific fame after the 1974 discovery of the Mammoth Site. In the 21st century, it remains a primary destination for wellness tourism and Ice Age research.

Demographics & Population

The 2026 population is approximately 3,600. The demographics are White (81%), Native American (12%), and Hispanic or Latino (2%). The median age is high (~59 years), reflecting its status as a retirement and veteran-centric community. The economy is driven by healthcare (VA Black Hills Health Care System), tourism, and regional ranching.
