There is so much to say about these wonderful caves. I love them. We try to go as often as possible. The price for the caves is $12.00. Some helpful tips: bring an extra towel (they do provide one but I always bring one from home too), bring a reusable water bottle (extremely important to stay hydrated), and bring a swimsuit (they have swimsuits for rent but I prefer my own).
From the website (http://www.yampahspa.com/caves.html): 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 F. 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. 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. Cold water and small tubs are also available for cooling off in the caves.
The Ute Indians who originally inhabited this region visited these caves for centuries, and regarded them as a sacred place of healing and rejuvenation. The Vapor Caves purify body and spirit as they soothe away aches and pains. The Indians had done much to spread the fame of the hot mineral springs as a wonderful healing source.
