How Do Geothermal Hot Springs Form?
on Oct 1, 2026 | 5 minutes
Geothermal hot springs form when groundwater travels deep into the Earth, absorbs heat from the crust, and rises back to the surface carrying dissolved minerals. Along the way, the water moves through ancient rock layers that shape its unique mineral profile. In Glenwood Canyon, this natural process evolved alongside the Colorado River as it carved deeper into the landscape over millions of years. Today, four natural springs feed 16 geothermal pools at Iron Mountain Hot Springs, with temperatures ranging from 89 to 112 degrees Fahrenheit. How Are Geothermal Hot Springs Formed? Geothermal hot springs form when groundwater absorbs heat from the Earth's crust and rises to the surface enriched with minerals. Three key ingredients make this possible: Water, stored underground as groundwater Heat, held within the rock of the Earth's crust A pathway, created by cracks, faults, and porous rock The journey begins when rain and snow seep into the ground through cracks and faults. Gravity pulls the water deeper, where it collects in porous layers of rock and gradually warms. As the water heats, pressure and buoyancy guide it back toward the surface. It naturally rises through available pathways. By the time it reaches the surface, it carries dissolved minerals gathered during its long underground journey. This process continues beneath Iron Mountain Hot Springs every hour of every day. The water guests soak in is the final stop in a journey that began deep below Glenwood Canyon. Where Does the Heat Come From? The heat inside a hot spring comes from geothermal energy stored in the Earth's crust. The deeper you travel below the surface, the warmer the rock becomes—a natural increase geologists call the geothermal gradient. Groundwater that circulates deep enough comes into contact with these warmer rock layers and absorbs their heat. In general, deeper circulation produces hotter water at the surface. Some hot springs are heated by nearby volcanic activity, but a volcano is not required for geothermal hot springs to form. Colorado has no active volcanoes, so the springs in Glenwood Canyon rely on deep water circulation and heat stored within the Earth's crust. The National Park Service geology of hot springs explains how this same process creates hot springs across the country. Beneath Iron Mountain Hot Springs, the Earth's natural heat keeps the water flowing warm year-round. How Does Water Collect Minerals Underground? Water collects minerals by dissolving them from ancient rock layers on its underground journey. Warm water can dissolve minerals more readily than cold water, and the longer it remains in contact with surrounding rock, the more mineral-rich it can become. Every hot spring develops a chemical signature based on the geology it passes through. Limestone, iron-bearing rock, and mineral veins can each contribute something different to the water. When mineral-rich water reaches the surface and begins to cool, some of those minerals may be left behind, creating the colorful deposits often seen around natural springs. The water at Iron Mountain Hot Springs contains 14 naturally occurring minerals, including iron, sulfate, and magnesium. Iron leaves behind the rust-orange color seen on nearby rock and helped give Iron Mountain its name. Learn more about the mineral profile and water sources at Iron Mountain Hot Springs. How Did the Springs in Glenwood Canyon Form? The springs in Glenwood Canyon shifted with the Colorado River as the river carved deeper over time. Over millions of years, the river cut through layers of rock, reshaping the canyon and influencing where the springs reached the surface. Today, the canyon walls rise high above the Colorado River while the springs emerge near river level. Water beneath Iron Mountain Hot Springs still moves through ancient rock shaped by this ongoing geological process. Together, the area's hot springs and caves form the only known system of its kind in the Southern Rocky Mountains. The National Park Service recognized the significance of these connected features in December 2023 through a National Natural Landmark designation shared by Iron Mountain Hot Springs and Glenwood Caverns Adventure Park. Read more about the National Natural Landmark hot springs designation and what makes this landscape so rare. How Do Four Natural Springs Feed Iron Mountain Hot Springs? Four natural springs feed 16 geothermal pools at Iron Mountain Hot Springs, with temperatures ranging from 89 to 112 degrees Fahrenheit. The water retains its natural mineral content as it flows into the pools, where guests can find a comfortable temperature or move between cooler and warmer waters. Set beside the Colorado River, the pools offer views of Iron Mountain and Mount Sopris and an open-air soaking experience in every season. For a refreshing contrast, three cold plunge pools range from 45 to 65 degrees Fahrenheit, giving guests another way to explore different temperatures during their visit. What Separates a Hot Spring From a Geyser? A hot spring releases heated groundwater steadily, while a geyser erupts under pressure at intervals. Geysers depend on narrow underground passages that trap water and steam. As pressure builds, the water eventually erupts above the surface. Hot springs have more open underground pathways, allowing heated water to rise and flow continuously. Other geothermal features include fumaroles, which primarily release steam, and mud pots, which form where limited water mixes with clay and heated gases. The four natural springs that feed Iron Mountain Hot Springs follow the calmer pattern, bringing geothermal water steadily to the surface without the pressure-driven eruptions of a geyser. How Do Inspired Mineral Pools Differ From Natural Springs? Inspired mineral pools start with freshwater and add precise mineral formulas, while natural springs arrive already enriched. Both contain dissolved minerals, but those minerals reach the water in different ways. In a natural geothermal spring, water collects its mineral content as it travels through underground rock. Engineered mineral pools begin with freshwater and use carefully developed formulas to recreate the mineral profiles of well-known waters from around the world. The WorldSprings pools at Iron Mountain Hot Springs follow this approach. Twelve pools are inspired by famous mineral waters, including the Dead Sea, the Blue Lagoon, and Vichy. The Jetted Mineral Spa offers another take on the concept, recreating the mineral profile of Zion Canyon Hot Springs. This means guests can experience natural geothermal pools and Inspired mineral pools in one location. Our guide to hot springs mineral absorption takes a closer look at how the minerals in both types of water interact with the skin. Soak Where the Process Still Runs Geothermal hot springs form underground over long spans of time and surface carrying the minerals of their journey. That natural cycle is still happening beneath Iron Mountain Hot Springs. Water continues to travel downward, warm within the Earth's crust, collect minerals, and rise again to the surface. Reserve your soak in the geothermal pools in Glenwood Springs and experience the final step of that journey firsthand. Book in minutes. Soak for hours. Feel good for days. Frequently Asked Questions Does rain or snow feed hot springs? Yes. Most hot spring water beginsas rain or snow that seeps underground through cracks and faults. From there, it can spend years—or much longer—traveling below the surface before returning as heated spring water. Why do some hot springs run hotter than others? The depth of the water's underground circulation and how quickly it rises helpdetermine its surface temperature. Water that travels deeper is exposed to hotter rock, while water that rises quickly canretain more of that heat. Can hot spring temperatures change over time? Yes. Hot spring temperatures can change as rivers, rock formations, and underground pathways shift. The springs in Glenwood Canyon have moved over millions of years as the Colorado River carved deeper into the landscape. How hot are the pools at Iron Mountain Hot Springs? Every geothermal pool ismaintained at a temperature between 98 and 112 degrees Fahrenheit. With cooler and warmer options located close together, guests can choose their pools based on personal preference. Do hot springs freeze in winter? No. A consistent flow of geothermally heated water keeps hot springs warm throughout the year. At Iron Mountain Hot Springs, winter brings the memorable contrast of rising steam, warm water, and snow-covered canyon views. Do hot springs exist on every continent? Yes. Geothermal springs can form anywheregroundwater, heat from the Earth's crust, and underground pathways come together. Colorado alone is home to dozens of named hot springs. What is the difference between a hot spring and a mineral spring? A mineral springcontains a high concentration of dissolved minerals at any temperature, while a hot spring is defined by water that rises naturallywarm. The water at Iron Mountain Hot Springs qualifies as both.
National Natural Landmark: Iron Mountain Hot Springs
on Sep 4, 2026 | 4 minutes
What National Natural Landmark Status Means for Iron Mountain Hot Springs Iron Mountain Hot Springs was designated a National Natural Landmark by U.S. Secretary of the Interior Deb Haaland on December 13, 2023. The recognition from the National Park Service honors Iron Mountain Hot Springs as the only known hot springs and cave system of its kind in the Southern Rocky Mountains. Iron Mountain is now one of more than 600 National Natural Landmarks nationwide. Iron Mountain Hot Springs was founded by the Beckley family, who pursued the designation as part of their long-running commitment to preserving the area's natural resources. Guests can still soak in these nationally recognized geothermal waters, drawn from four natural springs into 16 pools ranging from 98 to 108 degrees Fahrenheit. What Is a National Natural Landmark? The National Natural Landmark Program has identified and supported the conservation of the country's most outstanding natural sites since 1962. Landmarks sit on both public and private land, and for private owners like the Beckley family, participation is entirely voluntary. Sites earn the title based on five criteria: outstanding condition, illustrative character, rarity, diversity, and value to science and education. You can find full program details on the National Natural Landmarks program page. How Iron Mountain Hot Springs Earned National Natural Landmark Status Steve and Jeanne Beckley pursued the designation to have this unique geological site formally documented, and the review took years of geological evaluation before it was approved. The honor reflects what's happening beneath the surface — not a marketing claim, but a federal finding. U.S. Senator Michael Bennet publicly recognized the designation, calling attention to the hot springs as a treasured Colorado landmark and praising the Beckley family's conservation work. The Geology That Makes It Rare Over millions of years, the Colorado River cut deeper into Glenwood Canyon, eroding the Leadville Limestone beneath the area and carving the pathways and chambers that shaped this unique underground system. Naturally heated mineral water still rises through those same ancient channels today, feeding four natural springs and carrying 14 naturally occurring minerals — including iron, sulfate, and magnesium — to the surface. During the review, federal scientists documented eight native cave species and 38 unique bacteria types across the connected cave and spring systems, confirming an underground ecosystem that exists nowhere else on Earth. Many of the geological processes that created it are still active, giving researchers a rare, living window into the past. How Landmark Status Protects the Springs Designation doesn't change ownership or day-to-day operations, and guests soak exactly as they always have. What it does add is national recognition, technical conservation support, and access to potential grant opportunities that help protect the site's geology for future generations. Soaking in a National Natural Landmark People have gathered on this stretch of river for centuries. The first bathhouse was built here in 1897, and today that history carries a new distinction: a federal designation recognizing the springs as a National Natural Landmark. The property's 16 geothermal pools, fed by these notable springs, now sit amongst 35 pools along the banks of the Colorado River, with views of Iron Mountain and Mount Sopris. Iron Mountain Hot Springs is open daily from 9:00 AM to 10:00 PM, excluding planned closures, Thanksgiving Day, Christmas Day, and unforeseen circumstances. Other Colorado National Natural Landmarks Colorado is home to more than a dozen National Natural Landmarks, including: Hanging Lake — Glenwood Canyon, just a short drive from Iron Mountain Hot Springs Garden of the Gods — Colorado Springs Roxborough State Park — Douglas County Spanish Peaks — southern Colorado Protecting the Springs for the Future: Don't Mine Glenwood The same fragile limestone groundwater network that makes Iron Mountain Hot Springs geologically significant is currently at risk from a proposed quarry expansion just north of town. Rocky Mountain Industrials (RMI) is seeking Bureau of Land Management approval to more than triple the footprint of its Mid-Continent Limestone Quarry — from about 16 acres to 56 acres — including new blasting and mining several hundred feet upslope, near the unstable cliff left by a 2023 rockslide. Local officials, the nonprofit Glenwood Springs Citizens' Alliance, and Colorado's congressional delegation have raised concerns that expanded mining could damage the geothermal groundwater network feeding the hot springs, along with local air quality, traffic, and tourism. In response, Senators Michael Bennet and John Hickenlooper and Representative Jeff Hurd introduced the bipartisan Glenwood Hot Springs Protection Act, aimed at stopping the BLM from approving the expansion. We stand with our community in supporting this effort. If you'd like to help protect the water that feeds these landmark springs, visit loveglenwood.org to learn more and contact your member of Congress about the Glenwood Hot Springs Protection Act.

What Hot Springs Minerals Actually Do To Your Body
on Aug 17, 2026 | 5 minutes
There’s something special about soaking in naturally mineral-rich water. For centuries, people have sought out hot springs for the chance to relax, recharge, and enjoy the unique qualities of geothermal water. But what actually happens when you soak? Does your skin absorb the minerals in the water? And what makes a hot spring soak feel so restorative? The answer is a little more interesting than a simple yes or no. At Iron Mountain Hot Springs, our geothermal waters rise to the surface through four natural springs beneath Glenwood Springs. Along their journey through the earth, the waters pick up naturally occurring minerals from the surrounding geology, creating a distinctive mineral profile that is part of what makes our hot springs unique. What Happens When You Soak in Mineral-Rich Water? When you sit in a hot spring pool, your skin comes into direct contact with the minerals naturally dissolved in the water. Your skin is an important protective barrier, so it doesn't absorb minerals as readily as your digestive system does. Does your body absorb minerals from hot springs? Research continues to explore how certain minerals interact with the skin during bathing, including whether some may enter the outer layers of the skin. Exactly how much is absorbed—and the full effect on the body—remains an area of study. So, while a soak isn't a substitute for getting essential minerals through your diet, there's something uniquely enjoyable about surrounding yourself in naturally mineral-rich geothermal water. And the minerals aren't working alone. Why Does a Hot Spring Soak Feel So Good? Part of the magic of a hot spring is that several things happen at once. Warmth, buoyancy, water pressure, and the naturally occurring minerals in the water all come together to create a deeply relaxing experience. Heat Helps You Relax Warm water encourages your blood vessels to widen and increases circulation near the skin and muscles. That warmth can help loosen tight muscles and create the familiar feeling of settling into a hot spring and letting the day's tension melt away. It's one reason a soak feels especially good after hiking, skiing, traveling, or simply spending a long day on your feet. Buoyancy Gives Your Body a Break There's a reason you feel lighter in the water. Buoyancy supports your body weight, taking pressure off your joints and allowing your muscles to relax. Your knees, hips, back, and other weight-bearing areas get a break while you float and soak. Water Pressure Supports Circulation Water creates gentle pressure around your body while you're immersed. This pressure can help support circulation, particularly in your arms and legs. Together, heat, buoyancy, and water pressure create many of the physical benefits associated with warm-water immersion. The Added Experience of Mineral-Rich Water So where do the minerals fit in? They're part of what makes a natural hot spring different from an ordinary warm-water soak. Mineral waters develop their unique characteristics as groundwater travels through layers of rock underground. Along the way, the water picks up naturally occurring minerals before emerging at the surface. At Iron Mountain Hot Springs, that journey happens deep beneath Glenwood Springs. Our four natural springs produce geothermal water containing 14 naturally occurring minerals, creating a distinctive mineral profile that is part of what makes our waters unique. Discover what's in our geothermal waters What Minerals Are Found in Hot Springs? Different hot springs have different mineral compositions depending on the geology beneath them. At Iron Mountain Hot Springs, our waters contain minerals including magnesium, sulfate, and iron. Magnesium Magnesium plays an important role in normal muscle and nerve function and is one of the minerals most commonly associated with mineral bathing. Sulfate Sulfate occurs naturally in many mineral waters and has long been part of traditional bathing practices. Iron Iron is one of the defining minerals in our geothermal waters—and it's even part of our name. The iron-rich geology of the area is part of what makes Glenwood Springs' hot springs so distinctive. Together, these minerals create the naturally mineral-rich water that makes a geothermal soak at Iron Mountain a little different from your average hot tub. A Closer Look at Magnesium and Potassium Soaking Want to explore individual minerals? At Iron Mountain Hot Springs, our Sauna Summit features dedicated Magnesium and Potassium pools, giving guests another way to experience mineral-focused soaking. These pools are part of a larger contrast therapy experience where you can move between warm and cold water, sauna heat, and relaxation. Explore Sauna Summit and our hot springs pools Why Combine Hot and Cold Water? There's a reason contrast therapy has become a favorite recovery ritual. Moving between warm and cold water creates noticeable changes in your body's response to temperature. Warm water encourages blood vessels to widen, while cold water causes them to narrow. At Sauna Summit, you can build your own rhythm of heat, cold, soaking, and rest. And after spending time in the warmth, that first cool plunge can be surprisingly invigorating. The result? You leave feeling refreshed, relaxed, and ready to do it all over again. More Than Just the Minerals Here's the thing about a hot spring: you don't have to choose one reason to love it. It's the warmth of the water. The feeling of weightlessness. The mineral-rich geothermal water surrounding you. The Colorado sunshine. The mountain views. The opportunity to slow down for a while. And maybe most importantly, the chance to step away from everything else and simply soak. The science supports many of the physical effects of warm-water immersion, while the experience itself is something you have to feel for yourself. Experience Mineral-Rich Hot Springs in Glenwood Springs At Iron Mountain Hot Springs, you can experience 16 geothermal pools, naturally mineral-rich water, dedicated magnesium and potassium pools, and the heat-and-cold experiences of Sauna Summit. Come for the hot springs. Stay for the feeling. Take your time. Move between pools. Try something new. Find your favorite temperature. And let the water do what hot springs have always done best: give you a reason to slow down. Compare passes and book your soak

on May 26, 2026 | 6 minutes
After hiking and biking the trails of Glenwood Springs, recover mind and body at Iron Mountain Hot Springs. Discover the wellness benefits of mineral soaking and sauna therapy after your next outdoor adventure. Adventure Hard, Recover Well In Glenwood Springs, summer means practically living outside. One minute you’re pedaling the Glenwood Canyon Recreation Trail with the Colorado River rushing beside you, and the next you’re climbing rugged switchbacks on Red Mountain’s Cross trail. Recreation is an integral part of the Glenwood Springs experience. But every great day on the trails deserves an equally rewarding recovery. That’s where Iron Mountain Hot Springs comes in. After miles of hiking, biking, climbing, and exploring, soaking in mineral waters and unwinding in steam and sauna spaces can help your body reset, and your mind recharge. And the best part? You don’t have to be a professional athlete, wellness influencer, or meditation expert to benefit. Recovery isn’t reserved for elite competitors. It’s for regular people who love being active outdoors and want to feel good doing it again tomorrow. Trails That Earn the Soak Whether you prefer smooth paved paths or rugged dirt terrain, Glenwood Springs offers trails that invite adventure mile after mile. Smooth Paved Paths Rio Grande Trail. A rails-to-trails project that follows the Roaring Fork River from Glenwood Springs to Aspen. It’s perfect for biking, walking, jogging, or a relaxed bike ride with mountain and river views all along the way. Glenwood Recreation Trail. A paved trail that wends its way along the Colorado River through Glenwood Canyon, offering stunning vistas of a landscape etched over time by running water. Atkinson Canal Trail. A short, mellow, but rewarding route popular for strolling, running, and biking, offering Roaring Fork River access for fishing and wading. Rugged Dirt Trails Red Mountain Trails. Thanks to panoramic views of Glenwood Springs, this trail is a local favorite. It features steeper climbs, winding switchbacks, and, for bikers, flowy downhills with bonus hang time. Wulfsohn Trails. These hilly dirt trails through scrubby terrain offer a quieter, tucked-away feel, close to town, while still delivering a fun challenge. Doc Holliday Trail. A scenic route blending local history with a short, uphill hike or ride to Linwood Cemetery, the final resting place of gambler and gunslinger, John “Doc” Holliday. Jess Weaver Trail.

Why Mineral Waters Feel So Good There’s a reason people have been soaking in hot mineral waters for centuries. Warm water naturally helps relax tight muscles, while buoyancy reduces pressure on joints and connective tissue. After a long ride or hike, that combination alone can feel transformative. Mineral-rich waters may also help support circulation and ease physical tension built up from repetitive movement and exertion. The heat encourages blood flow, helping oxygen and nutrients move through tired muscles while promoting relaxation throughout the body. At Iron Mountain Hot Springs, the experience goes beyond simply “taking a hot bath.” With 30+ pools, all varying pool temperatures, including cold plunges, guests can easily customize their recovery experience. And while the physical benefits are easy to feel, the mental reset might be even more valuable. Recovery for the Mind, Too Outdoor recreation challenges the body, but it also fills the mind with stimulation that includes navigation, elevation changes, adrenaline, weather shifts, and physical exertion. After hours of activity, soaking provides a rare opportunity to simply pause. The transition from movement to stillness can help calm the nervous system and create a sense of mental clarity that often gets lost in daily life. Even a short soak can leave you feeling grounded, refreshed, and ready to reconnect with yourself, your travel companions, or simply the moment. Elevate Recovery at Sauna Summit Iron Mountain Hot Springs recently expanded its wellness offerings with its new Sauna Summit—a collection of five unique globally-inspired sauna experiences—creating even more ways to recover after outdoor adventures.

If you spent the day hiking, biking, walking, climbing, or exploring Glenwood Springs, your body has already done the work. Where Every Trail Can Lead To Bliss At Iron Mountain Hot Springs, the reward for adventure is the soak afterward! Learn more and make your reservation to relax, restore, and recover today!
Springtime at Iron Mountain Hot Springs
on Apr 29, 2026 | 4 minutes
Spring is a fresh start; it’s always surprising and overflowing with possibilities. It’s also one of the best times of the year for riverside relaxation at Iron Mountain Hot Springs. Find out all the reasons we’re addicted to springtime vibes. Every season has its own highlights, but of the four, spring tops our list for visiting Iron Mountain Hot Springs. Verdant, moody, and indecisive, it keeps us on our toes but always captures our hearts. When it comes to spring, these are a few of our favorite things: A slower pace. Technically, a shoulder season, spring is the calm inhale before Memorial Day, the unofficial start to the summer season. Between now and then, the kids are still in school, and there are fewer visitors overall. That means the pace is a little slower, the vibe is more laidback, and you can settle into the simple joy of moving from pool to pool. There are 35 pools in all, each one a slightly different temperature and offering its own perspective on the river and mountain panoramas. Choose Your Experience. Iron Mountain pricing allows you to enjoy the waters your way. Our Premier Access pass includes admission to the entire property—the 21+ WorldSpring waters, the newly opened Sauna Summit, two cold plunges, two mineral-intensive pools, as well as access to all the original Geothermal Hot Springs. Guests also have the option to purchase Select Access passes for the original springs area only. With 16 geothermal soaking pools, a Family Zone with a freshwater pool, a cold plunge, and a fire pit, it’s the ideal spot for parents and children to unwind together. Baby birds. Spring is baby time! Waterfowl abound at Iron Mountain Hot Springs. They like the river views just as much as any of us. We guarantee you’ll be delighted to see a mama mallard and her retinue of fuzzy ducklings queuing up to waddle around the campus or wade into the river. In addition to ducks of all varieties, you might spot eaglets, bald-headed vulture chicks, and even—on rare occasions—a cygnet gliding alongside her long-necked swan mom. It’s these kinds of quiet, unscripted moments that pair perfectly with a long soak. River rats return. Don’t worry—we look forward to the return of these lively river regulars every year. “River rats” is a term of endearment for those who like to play on the water—anglers, rafters, and paddle-boarders. They can’t get enough of it, and for those soaking in the pools along the terraced banks, they add a bit of local color to the experience. One minute you’re watching the steam rise off the water, the next you’re waving at a crew of rafters floating by. Moody days. Spring is notoriously unpredictable, and that’s exactly what we love about it. Every day is different, and every day is a great day to soak, no matter what kind of mood Mother Nature is in. Mornings are especially beautiful—low-lying clouds hugging Red Mountain, steam rising from the pools permeated by a quiet calm before the day gets going. And when those quick mountain storms roll in? There’s no need to retreat. Just sink a little deeper into the warm mineral water or make your way up to Sauna Summit, featuring the resort’s five new globally-inspired saunas.The contrast of heat and cool air feels especially invigorating in spring’s shifting weather. Lounging in sunshine. Most days, however, spring leans into its brighter side—sunny, warm, and just right for lingering a little longer than planned. This is the season for claiming a lounger, closing your eyes, and letting the combination of fresh air and mineral water do its thing. It’s also the perfect excuse to ease into an unhurried afternoon with a light bite and drink from the Sopris Café or the Sandbar Café. Spring Into Iron Mountain Hot Springs Spring days won’t last long, enjoy this budding, but fleeting season now. Learn more and make reservations to visit Iron Mountain Hot Springs today!
