Hot Sulphur Springs Resort and Spa
35,000 feet below the surface of the earth, the heat of volcanic rock is released through countless fissures that spread out through the earth's crust. In Hot Sulphur Springs, CO, there are seven natural springs flowing above the largest fissure that have been flowing constantly for hundreds of years, surfacing at about 104ºF to 126ºF. Over 200,000 gallons of natural hot mineral-rich water flow through our 21 mineral pools and baths every day at controlled temperatures of 95º to 112ºF. We do not add chemicals, filter or re-circulate our mineral water.
