Three major springs are located in the Warm Springs Valley of the Allegheny Mountains in western Virginia along US route 220--the Warm, Hot and Healing--all now owned by Virginia Hot Springs, Inc. The Homestead, a large and historic luxurious resort, is located at Hot Springs. The odorless mineral water used at The Homestead spa flows from several springs at temperatures ranging from 39C to 41C (102 to 106F). It is piped to individual, one-person bathtubs in separate men's and women's bathhouses, where it is mixed to provide an ideal temperature of 40C (104F). Tubs are drained and refilled after each use so that no chemical treatment is necessary. Mineral water from the same springs is used in an indoor swimming pool maintained at 29C (84F), and an outdoor swimming pool maintained at 22C (72F)
