About Yampah Hot Springs and Vapor Caves
Yampah Hot Springs and Vapor Caves, Colorado is a day spa and geothermal cave facility at 709 East Sixth Street in Glenwood Springs, housing the only known naturally occurring vapor caves in North America. Three adjoining underground rock chambers are fed by the Yampah spring at 125 degrees Fahrenheit, producing mineral steam that reaches 110 to 113 degrees inside the cave. Visitors descend a staircase into the cave system and sit on marble benches in the dimly lit chambers. Sessions of 10 to 12 minutes with cooling breaks are recommended. The facility is day-use only with no overnight lodging.
The Ute used this site for centuries, calling it Yampah, meaning Big Medicine. The building opened formally in 1893 and has operated continuously since. The same geothermal source feeds both the vapor caves and the adjacent Glenwood Hot Springs Pool. Natural hot springs in Colorado from this source carry 34 minerals and trace elements, making the water among the most mineralised in the state.
The spa also offers private Japanese-style mineral soaking tubs for one or two guests, massage, facials, body wraps, and salon services. A solarium and outdoor deck provide recovery spaces between cave sessions. The facility is wheelchair accessible at street level and open seven days a week year-round.

Suitability & Accessibility
Who Should Visit Yampah Hot Springs and Vapor Caves
Yampah Hot Springs and Vapor Caves suits adults and older teenagers who are comfortable in an enclosed, high-temperature steam environment and want an experience genuinely different from outdoor pool soaking. The steam cave format with 110 to 113 degree temperatures and underground marble bench seating works well for visitors interested in deep relaxation, mineral steam therapy, or the historic and cultural context of the site.
The vapor caves are not recommended for young children. Cave temperatures are far above safe levels for infants and toddlers, and the enclosed underground setting is not suited to young guests. The facility's own guidance directs families with children to the adjacent Glenwood Hot Springs Pool, with parents alternating cave time while the other supervises children at the pool. This makes Glenwood Springs a practical destination for mixed groups.
The building is wheelchair accessible at ground level. The vapor caves require descending a staircase, which limits full cave access for wheelchair users. Spa services, the solarium, and private mineral baths may be accessible without the descent, and guests with mobility considerations should call ahead to confirm which areas are reachable. Those searching for hot springs near Glenwood Springs will find Yampah the most historically unusual option in the area, offering an underground experience unlike any other hot spring facility in the state.
Safety & Etiquette
Yampah Hot Springs and Vapor Caves Safety Tips
Yampah Hot Springs and Vapor Caves is generally safe for healthy adults when used according to the facility's guidelines, but the enclosed steam cave environment at 110 to 113 degrees requires careful management of time and cooling. Sessions of 10 to 12 minutes with breaks in between are recommended. Staying longer without cooling can lead to overheating or lightheadedness. Guests who feel unwell at any point should exit the cave immediately and rest in the cooling room or solarium.
People with heart conditions, high blood pressure, respiratory conditions, pregnancy, or claustrophobia should consult a physician before entering the vapor caves. The cave environment is dim and enclosed; those prone to anxiety in confined spaces should be aware before descending. Cold water and cooling buckets are available inside the cave for immediate temperature regulation.
The staircase into the cave and the cave floor are wet. Grip footwear is recommended when moving between changing areas and the cave. The mineral content of the steam and water is high in sulphate, nitrate, zinc, and potassium; guests with known mineral sensitivities should note this. The facility recommends checking with a doctor before booking if any medical conditions are present.
Alcohol before or during cave use increases the risk of overheating and should be avoided. Drinking plenty of water before and after a cave session is strongly advised. The cave staircase is narrow; move carefully and hold the rail. Staff are trained to monitor guest wellbeing and may stop any service if safety concerns arise. Standard spa hygiene applies, including showering before entering any water area. The vapor caves are not suitable for young children.
