Two soaking pools have transfer walls and grab bars that allow a person with upper body strength to leave a mobility device and transfer onto the wall and into the water. All buildings are accessible, and there are two changing rooms with showers for families and caregivers. For current access to WorldSprings, mobility access is limited temporarily while a new locker building is under construction. Once the new locker building is complete, ADA access will be located near the general access property’s Summit Station towel pick-up area. Guests with mobility issues may request on-site transportation via our ADA golf cart.

What minerals are present in the hot springs water?

There are more than 14 different minerals found in the analysis of our geothermal waters. Iron, sulfate, chloride, sodium, and calcium are the five most abundant minerals in the soaking pools. Iron and sulfate are known for their relaxing qualities. Each of the WorldSprings pools includes different mineral formulas. Each pool is different; for example, the Blue Lagoon pool is rich in Silica, Potassium, and Boron minerals; the Vichy pool includes Bicarbonate, Silica, Sodium, and more minerals; the Hokkaido, the Japan pool, is naturally rich in Sodium, Sulphur, and Bicarbonate; the Turkey pools have large amounts of Bicarbonate, Sulphate, and Calcium; the Romania pool is rich in Iron, Magnesium, Potassium, and Calcium; the New Zealand pool incorporates Sodium, Sulfate and Potassium, the Italy pool is rich with Sodium, Sulfate, and Bicarbonate; and in the Bali pool, Sulfate, and Magnesium make up 74% of the minerals. 

Will the minerals in the water discolor my bathing suit?

Yes, it’s possible, as our natural mineral waters are rich in iron. We recommend you bring an extra swimsuit to Iron Mountain Hot Springs (like last year’s suit) and leave all jewelry at home or in your locker. Then, if our iron-rich water stains your suit, you’ll simply take home a souvenir and lasting memory.

Where does the hot water for Iron Mountain Hot Springs come from?

Several springs are emerging on the Iron Mountain Hot Springs property; the average temperature of the water from these springs ranges from 105 to 108 degrees. The water from our well is 120 degrees. The hot springs have been named Redstone, Gamba, Hobo, and CDOT, pushing 400 gallons per minute to our pools. The water is heated by geothermal heat from the Earth’s mantle.

Where does the hot water for the WorldSprings pools come from?

The water for the WorldSpring pools is the same freshwater used in our Family Pool, Jetted Spa, Confluence Pool, and Cold Plunge. This water is then carefully prepared to match the temperature and mineral content of famous baths and springs from across the globe.  Please note that this water does contain low levels of chlorine, as determined by the Glenwood Springs Water Department.

What is the difference between the waters on the General Access side and the water at WorldSprings?

The General Access side is our legacy section that features 19 different pools including our 16 Geothermal mineral pools. These Geothermal pools are all natural water with no additives. The water flows through the pools and discharges directly into the Colorado River. The large family pool and jetted spa have trace amounts of chlorine since they are not the geothermal waters. The temperatures of these pools vary depending on what mineral water is flowing to that pool. WorldSprings is inspired by some of the most famous hot springs on the planet. Each inspired pool uses a unique mineral formula designed to replicate these famous hot springs. With the use of filtration, trace amounts of chlorine and heat we have created a new encounter at an already memorable location sitting along the Colorado River. We take our water very seriously and follow all required procedures to ensure that what our guests enjoy is also beneficial. Both sections offer unique qualities that everyone should soak up.

Why is everyone required to sign a liability waiver?

Our insurance company requires us to have a signed liability waiver (Exención Por Actividades) for everyone that uses the property; plus, it informs guests of the safety rules, the natural terrain, and the natural untreated mineral waters. Children under 18 will require a parent’s signature.

What is the family pool like?

The family pool on the western portion of the Iron Mountain Hot Springs property is the largest of our pools. It is approximately 70′ x 35’ with 86,000 gallons of chlorinated fresh water, heated to a comfortable 95 degrees by the geothermal exchange. A smaller pool, our Jetted Spa, approximately 18′ x 8’, sits on the edge of the family pool with a perfect soaking temperature above 100. Parents can enjoy the hotter water while supervising their children below.

Are there other pools for soaking?

Yes! We have 16 natural geothermal springs and a WorldSprings-inspired pool connected with heated walkways. The walkways are heated to melt snow and prevent iciness in the winter months, but you’ll still want to bring a pair of sandals or slippers to keep your toes warm. Our pools are filled with natural geothermal water with a complete changeover in water every two hours. The temperatures will vary from pool to pool, providing guests with various soaking indulgences. Sorry, children under five are not allowed in the geothermal pool area, and children 5 to 13 must be accompanied by their parents or other adults. Those who purchase an upgrade to the WorldSprings pools will have access to additional pools, including 11 inspired pools by the most famous hot springs on the planet, one freshwater cold plunge pool, one freshwater pool with waterfalls, and one Dead Sea-inspired pool with waterfalls. Please note that guests aged 21 and over who visit the property with children under 14 will not be able to experience WorldSprings since children under 14 must be supervised by an adult. 

Are drones allowed?

Iron Mountain Hot Springs is a no-drone zone to respect our guests’ privacy. If you are a journalist, blogger, or travel writer, Contact our public relations representative to request high-resolution images and additional information.

Can I bring a speaker?

To respect the relaxation of our guests, Iron Mountain Hot Springs does not allow individual speakers to be brought on the property by guests. 

What should I bring for a wintertime soak?

We recommend coming dressed and prepared for changing Colorado weather conditions. To ensure your comfort, pack a pair of sandals to wear when walking between pools, a robe to stay warm, and we’ll supply two towels. This will provide additional warmth when you are outside the water, whether to get to another pool or when ordering food from our Sopris Café or the Sandbar Café on the WorldSprings property.

Where can guests go to smoke during their reservation?

We have a smoking section located in front of the bathhouse before you check-in. Guests wishing to smoke tobacco products during their reservation will need to exit the bathhouse and walk to this designated smoking area. Please know that the use of Marijuana is illegal in public places. Guests who use tobacco vaporizers must also use the designated smoking area. Guests who smoke inside the property in or near the pools will be removed from the property without a refund. Passholders will have their pass revoked without a refund.
