This Natural Underground Cave in Colorado Is Actually a Healing Subterranean Steam Spa

Imagine stepping into a world hidden beneath the Colorado mountains, a place where the earth itself breathes out warm, healing steam. For centuries, this natural wonder has been a sanctuary for those seeking relaxation and rejuvenation, a secret passed down through generations. It’s a spa experience unlike any other, powered entirely by geothermal energy, offering a unique way to detoxify and de-stress that you simply can’t find anywhere else.

This isn’t your typical day spa with piped-in music and standard treatments. Here, you descend into a network of underground rock caves, naturally filled with hot mineral water vapor. The air is thick with steam, hovering around a balmy 110-112°F, creating a natural steam room that soothes tired muscles, clears the mind, and purifies the body. It’s an ancient, almost mystical experience that connects you directly to the raw power and tranquility of nature.

This incredible destination is the one-and-only Yampah Spa & Vapor Caves in the heart of Glenwood Springs. Known as one of the few natural vapor caves in North America, it offers a truly unique wellness journey. Whether you’re a local in need of a reset or a traveler looking for an unforgettable Colorado experience, this place is a must-visit.

What We Love

The Vapor Caves

The main event, and for good reason! Descending the stairs into the dimly lit, labyrinthine caves feels like entering another world. You’ll find marble benches tucked into various nooks where you can sit and let the mineral-rich steam work its magic. The natural, earthy scent and the quiet drip of water create a deeply meditative atmosphere that melts stress away instantly.

You can move between the three adjoining caves, finding the temperature that’s just right for you. It’s recommended to take breaks every 10-15 minutes, heading to the cooling room or sipping some water to stay hydrated. This cycle of hot and cool is incredibly invigorating and leaves you feeling completely refreshed and renewed from the inside out.

Full-Service Spa

While the caves are the star, Yampah is also a comprehensive spa offering a wide array of treatments to complement your visit. After your steam session, when your muscles are warm and relaxed, it’s the perfect time for a deep-tissue massage. They also offer facials, body wraps, and manicures, making it easy to build a full day of pampering.

The staff are professional and attentive, ensuring your experience is tailored to your needs. Combining a cave visit with a treatment like a massage or a hydrating body polish elevates the experience from a simple visit to a truly holistic wellness retreat. It’s the ultimate way to treat yourself.

The Solarium

Between steam sessions, you’ll want a peaceful place to cool down and relax, and the Solarium is perfect for that. This bright, sun-filled room offers comfortable lounge chairs and a quiet atmosphere. It’s a serene space to read, meditate, or simply close your eyes and absorb the benefits of your cave experience.

The contrast between the warm, dark caves and the bright, airy Solarium is a key part of the therapeutic process. It allows your body to regulate its temperature and gives your mind a chance to process the deep relaxation. It’s a thoughtfully designed space that enhances the overall sense of tranquility.

Mineral Water Soaks

If you’re looking for another way to soak in the local geothermal goodness, Yampah offers private mineral baths. These tubs are filled with the same therapeutic hot springs water that creates the vapor in the caves. It’s a more private and intimate way to enjoy the healing properties of the water.

You can book a solo soak or a bath for two, making it a wonderful option for couples. The warm, mineral-rich water is fantastic for soothing sore joints and muscles, and it’s a perfect add-on to your cave visit for the ultimate relaxation package. It’s a quiet, personal indulgence that feels incredibly luxurious.

Historic Roots

Part of the charm of Yampah is its incredible history. The Ute people, native to the region, considered these caves a sacred place for healing and purification for centuries. The spa itself has been in operation since 1893, making it a true Colorado institution with a story to tell.

Knowing that you are participating in a wellness tradition that is hundreds of years old adds a layer of depth to the experience. You can feel the history in the stone walls of the caves. It’s not just a spa; it’s a connection to the past and a tribute to the enduring power of nature.

Atmosphere & Setting

The vibe at Yampah is one of profound peace and tranquility. From the moment you walk in, the focus is on quiet relaxation. The decor is simple and clean, letting the natural elements be the focus. The facility is co-ed, and guests are respectful of the serene environment, speaking in hushed tones and moving mindfully through the spaces.

Down in the caves, the atmosphere is even more meditative. The dim lighting and the natural rock formations create a cocoon-like environment that encourages you to turn inward and disconnect from the outside world. It’s a grounding, earthy, and deeply calming setting that feels both rustic and restorative.

Value (Is It Worth It?)

For such a unique natural phenomenon, access to the vapor caves is quite affordable, making it an excellent value. A day pass allows you unlimited time in the caves and access to the relaxation areas for the entire day, so you can come and go as you please. This allows you to truly take your time and not feel rushed, which is a huge plus.

When you consider the detoxification and relaxation benefits, the cost is more than justified. Spa treatments are priced competitively with other high-quality day spas, but the experience is enhanced by the one-of-a-kind setting. It’s an investment in your well-being that pays dividends in how you feel for days afterward. Absolutely worth it!

Other Considerations

What to Bring: You’ll need a swimsuit for the co-ed caves. The spa provides towels, robes, and lockers for your belongings. It’s also a great idea to bring a water bottle to stay hydrated, though they have water stations available.

Age Limits: Guests must be 18 years or older to use the spa facilities, including the vapor caves. This ensures a quiet, adult-oriented atmosphere for all visitors.

Reservations: While you can often walk in for a cave visit, it’s highly recommended to book any additional spa treatments (massages, facials, etc.) well in advance, as they fill up quickly, especially on weekends.

Parking: There is a dedicated parking lot for the spa, which is a convenient perk in downtown Glenwood Springs. Street parking is also available nearby if the lot is full.

Health Considerations: The caves are very hot and steamy. It’s important to listen to your body and take frequent breaks. If you are pregnant or have certain health conditions like heart problems or high blood pressure, you should consult your doctor before visiting.

So, if you’re looking for a way to unwind that goes beyond the ordinary, a visit to Yampah Spa & Vapor Caves is an absolute must. It’s a chance to experience a powerful natural wonder, connect with a piece of Colorado history, and give your body and mind the deep, restorative break they deserve.

It’s the kind of place you’ll tell your friends about for years to come—a truly special gem hidden right in Glenwood Springs. Grab your swimsuit, clear your schedule, and get ready to breathe deep and relax in a way you never have before. You won’t regret it!
