The Yampah Spa Vapor Caves are natural underground hot mineral water steam baths located in the historic hot springs mountain retreat of Glenwood Springs, Colorado. Hot mineral waters flow through the cave floors at 125 degrees Fahrenheit. to create our natural geothermal steam baths. The Vapor Caves consist of three adjoining underground rock chambers. Visitors descend a stairway inside the main building and pass through a stone corridor into the caves. An atmosphere of well-being pervades throughout the soothing stillness of the caves. Relax on slab marble benches in the rocky alcoves, and inhale the natural steam vapor in the warm, dimly lit cave chambers. Stress and tension melt away effortlessly. Vapor Cave temperatures average 110 -112 degrees F., allowing repeated visits of 10-12 minutes separated by brief rests in a nearby cooling room, or upstairs in the spacious solarium. A cold water shower and small tubs (to be filled with cold water from the shower) are available for cooling off in the caves.

The hot springs source is in the hillside behind the spa. The natural, untreated therapeutic water contains 34 minerals and trace elements, and is especially high in sulfate, nitrate, zinc and potassium. The hot springs water flows through the caves at a simmering 125 degrees F. by way of narrow, shallow channels. Visitors to the 131 year old Yampah Spa and Vapor Caves continue to experience a long tradition of healing and rejuvenation. The caves and a wide range of excellent spa treatments combine to purify body and spirit as they soothe away aches and pains.
