There’s a particular alchemy that happens when you slip into 104-degree mineral water while snowflakes dissolve on your eyelashes and the Rocky Mountains tower above you like geological sentinels. It’s not quite meditation, not quite decadence, but something that exists in that perfect space between the two. This is the hot springs in coloradoi experience, and it’s one of the state’s most compelling reasons to venture into the mountains beyond the ski slopes and hiking trails.

Colorado sits atop remarkable geothermal activity, where heated groundwater rises through fissures created millions of years ago when tectonic forces lifted the Rockies skyward. The result? Over 30 developed hot springs resorts and countless primitive soaking spots scattered throughout the state, each offering its own particular interpretation of what happens when mineral-rich water meets mountain air.
Does Colorado Have Any Natural Hot Springs?
Absolutely. Colorado boasts one of the highest concentrations of natural hot springs in the United States. According to Colorado Hikes and Hops, the state features 23 major hot springs destinations ranging from primitive natural pools requiring hikes (like Radium and Conundrum Hot Springs) to developed resort facilities.
The hot springs result from geothermal heating deep underground. Water seeps through rock layers, gets heated by the earth’s interior, and resurfaces at temperatures ranging from 90°F to over 160°F. This water is naturally infused with minerals including sulfur, calcium, magnesium, potassium, and trace elements that have been associated with therapeutic benefits for centuries.
Long before European-Americans settled in Colorado, Indigenous tribes including the Utes, Navajo, and Hopi recognized these waters’ healing properties. The Utes particularly prized several hot springs locations throughout the Western Slope, naming one “Pagosa” meaning “healing waters” in the Ute language.
Today, Colorado hot springs vary dramatically in character. Some remain primitive and free, accessed only by hiking. Others have evolved into full-service resorts with pools, spa treatments, lodging, and restaurants. The beauty of Colorado’s hot springs landscape is this variety. Whether you want rustic authenticity or polished comfort, the state delivers.
How Many Hot Springs Are in Colorado?
Colorado features over 30 developed hot springs resorts and numerous undeveloped natural springs throughout the Rocky Mountain region. The exact number depends on how you count. Major developed facilities number around 30, but if you include every primitive spring that bubbles up along mountain streams, the count exceeds 100.
The most concentrated clusters exist in several regions. Glenwood Springs hosts both the massive Glenwood Hot Springs Resort and the boutique Iron Mountain Hot Springs. Steamboat Springs features Old Town Hot Springs and the more primitive Strawberry Park Hot Springs. The Ouray area, often called the “Switzerland of America” for its dramatic mountain setting, contains numerous hot springs including Ouray Hot Springs Pool, Orvis Hot Springs, and Box Canyon Lodge’s private pools.
Near Rocky Mountain National Park, Hot Sulphur Springs Resort offers dozens of small pools at varying temperatures. In the San Luis Valley, Joyful Journey Hot Springs and Valley View Hot Springs provide more intimate experiences. And in Southwest Colorado, Pagosa Springs claims the world’s deepest geothermal hot spring, feeding The Springs Resort’s 25+ pools.
This geographical distribution means you’re never far from a hot springs experience regardless of where your Colorado adventures take you.
Best Hot Springs in Colorado: The Essential List
Mount Princeton Hot Springs Resort
Situated between Buena Vista and Salida at the base of the Collegiate Peaks, Mount Princeton Hot Springs Resort combines natural riverside soaking with developed pool facilities. The creekside pools offer perhaps Colorado’s most scenic hot springs setting, where Chalk Creek flows beneath towering Mount Princeton and its distinctive Chalk Cliffs.
The resort features multiple pools at varying temperatures, twin 700-foot waterslides (summer only), adults-only spa pools, and extensive lodging options. Overnight guests receive two days of hot springs access included with their stay. Day use costs approximately $25-35 per person depending on season.
The creekside experience particularly stands out. Natural springs feed pools built directly into the creek, allowing you to adjust your temperature by moving between hot spring water and cool creek water. In winter, steam rises dramatically against snowy peaks. In summer, the alpine setting provides relief from heat while maintaining that restorative soak.
Location: Nathrop, Colorado (between Buena Vista and Salida) What makes it special: Creekside soaking with spectacular Collegiate Peaks views
The Springs Resort & Spa, Pagosa Springs
The Springs Resort features over 50 hot spring pools ranging from 35°F to 112°F, fed by the Mother Spring which is the deepest geothermal hot spring on Earth. This luxury resort in downtown Pagosa Springs offers everything from cold plunge pools to steam grottos to adults-only wellness pools with mountain views.
The Mother Spring produces water at 144°F containing 13 different minerals including potassium, magnesium, zinc, lithium, iron, and manganese. The resort channels this water through an elaborate system of pools, allowing guests to find their perfect temperature.
Overnight guests enjoy 24-hour pool access, complimentary wellness activities including Aqua Yoga and forest bathing hikes, and exclusive access to salt-therapy saunas. Day passes are available for those not staying overnight, typically $40-50 per person.
The resort emphasizes luxury while maintaining connection to the natural hot springs. The Thermal Spa offers treatments, multiple restaurants provide dining options, and the riverside location creates a retreat atmosphere that justifies the premium pricing.

The sheer size impresses, but can also mean crowds during peak summer and winter holidays. The resort’s long history and family-friendly amenities have made it a Colorado institution, though those seeking intimate natural settings might prefer smaller facilities.
Location: Glenwood Springs (off I-70) What makes it special: Largest natural hot springs pool, historic resort, easy access
Iron Mountain Hot Springs, Glenwood Springs

Strawberry Park Hot Springs
Seven miles into the mountains from Steamboat Springs, Strawberry Park Hot Springs blends pure natural beauty with unique stone masonry thermal pools along Hot Springs Creek. This facility maintains a more primitive feel than resort-style hot springs, with pools built directly into the creek bed.
Five cascading pools range from about 104°F in the upper pools to significantly cooler temperatures in the lower pools as hot spring water mixes with creek water. The stone masonry work creates beautiful natural-looking pools despite human construction.
The setting delivers genuine mountain serenity. Surrounding forest, creek sounds, and mountain views transport visitors far from urban life despite being relatively close to Steamboat. The property offers camping (summer only) and rustic cabin rentals for overnight stays.
Important notes: The last two miles of road are unpaved. From November through May, Routt County law requires 4WD vehicles with snow tires or chains. Shuttle services operate from Steamboat.

Location: Hot Sulphur Springs (near Rocky Mountain National Park) What makes it special: Many small pools at different temperatures, convenient to RMNP
Natural and Primitive Hot Springs in Colorado
Beyond developed resorts, Colorado offers numerous primitive hot springs requiring hikes to access. These typically cost nothing, follow leave-no-trace principles, and often have clothing-optional etiquette.
Conundrum Hot Springs: Near Aspen, this requires an 8.5-mile hike gaining 2,500 feet elevation. The reward is two pools at about 100°F in spectacular alpine setting at 11,200 feet. Most visitors backpack in and camp overnight. The popularity has created management challenges, and the Forest Service now requires permits.
Radium Hot Springs: Along the Colorado River near Kremmling, Radium requires a steep but short hike. The primitive pools reach about 80°F, making them better for summer soaking. The riverside setting offers solitude and wildlife viewing.
Penny Hot Springs: Right alongside Colorado Highway 133 in the Crystal River Valley, Penny Hot Springs requires almost no hiking. The primitive pools where hot spring water meets the Crystal River offer free year-round soaking with spectacular Marble mountain views.
Rainbow Hot Springs: Near Pagosa Springs, Rainbow Hot Springs requires a 4.5-mile hike but rewards with natural pools in a backcountry setting. Less crowded than Conundrum, though still requiring permits during peak season.
These primitive springs offer authentic experiences but come with responsibilities. Pack out all trash, respect private property boundaries, be prepared for changing weather, and understand that water temperatures can vary significantly based on river flows and season.
What is the Number One Attraction in Colorado?
According to various tourism metrics, Colorado’s top attraction varies between Rocky Mountain National Park, Pikes Peak, Garden of the Gods, and hot springs destinations. However, hot springs collectively represent one of Colorado’s most distinctive and popular draws.
Colorado hot springs are one of the state’s most popular attractions, from luxurious hot springs resorts to hike-in natural wonders. The combination of therapeutic mineral water, spectacular Rocky Mountain settings, and year-round accessibility creates appeal that few other Colorado attractions match.
Unlike skiing (limited to winter) or hiking (challenging in winter), hot springs work in any season. In fact, many enthusiasts argue that winter delivers the ultimate Colorado hot springs experience, when 104-degree water meets sub-zero air in dramatic fashion.
Which Town is Famous for Its Hot Springs?
Several Colorado towns claim hot springs fame. Pagosa Springs literally translates to “healing waters” from the Ute language. Glenwood Springs has operated hot springs resorts since 1888. Steamboat Springs takes its name from the hot springs that early settlers thought sounded like a steamboat.
However, Ouray possibly holds the strongest claim to hot springs town status. This small mountain community of under 1,000 residents sits in a valley with abundant geothermal activity. Multiple hot springs operate within town limits, the dramatic San Juan Mountain setting creates stunning scenery, and the town actively promotes its “Switzerland of America” identity tied closely to hot springs culture.
The Million Dollar Highway connecting Ouray to Silverton ranks among America’s most scenic drives, and the Ouray Ice Park transforms the town into a winter climbing destination. But hot springs remain central to Ouray’s identity and economy.
Are Colorado Hot Springs Free?
It depends. Primitive natural hot springs accessed by hiking are typically free, though some now require Forest Service permits due to overuse. Examples of free hot springs include Radium, Penny, South Canyon, and (with permit) Conundrum.
All developed resort hot springs charge admission. Day-use prices typically range from $15-20 for municipal pools (Ouray, Salida) to $40-50 for luxury resorts (The Springs Resort, Mount Princeton). Many offer discounts for children, seniors, military, or local residents.
The value calculation depends on your priorities. Free primitive springs offer authentic natural experiences but minimal amenities. Resort hot springs provide changing facilities, varied pool temperatures, food service, and often easier access, justifying their costs for many visitors.
Are There Clothing-Optional Hot Springs in Colorado?
Yes, several Colorado hot springs allow or specifically permit clothing-optional bathing. Most primitive backcountry hot springs follow clothing-optional norms, though this varies by specific location and group present.
Among developed facilities, Strawberry Park Hot Springs becomes clothing-optional after dark (minors not permitted in evening). Valley View Hot Springs in the San Luis Valley operates as clothing-optional at all times. Orvis Hot Springs near Ouray is clothing-optional. Desert Reef Hot Springs near Florence follows clothing-optional policies.
Most large resort hot springs (Glenwood, Pagosa, Mount Princeton) require swimwear at all times given their family-friendly focus. Always check specific facility policies before visiting if this matters to your plans.
Are There Hot Springs Near Rocky Mountain National Park?
Yes. Hot Sulphur Springs Resort sits approximately 30 miles west of Rocky Mountain National Park’s west entrance near Grand Lake. The town of Hot Sulphur Springs has served hot springs enthusiasts since the late 1800s.
Indian Hot Springs near Idaho Springs provides another option, located about an hour from RMNP’s east entrance near Estes Park. While not immediately adjacent, these locations work well for visitors making RMNP the centerpiece of Colorado trips.
Strawberry Park Hot Springs near Steamboat Springs sits about 2.5 hours from RMNP, making it possible though not convenient for a same-day combination.
Best Time of Year for Hot Springs in Colorado
Every season offers distinct hot springs appeal. Winter (December through March) provides the classic Colorado hot springs experience. Soaking in 104-degree water while snowflakes fall creates magical contrast. The mountains wear dramatic snow cover, steam clouds billow dramatically in cold air, and après-ski soaking becomes irresistible after days on the slopes.
Spring (April-May) brings snowmelt and shoulder-season pricing. Mountain wildflowers begin blooming at lower elevations, and day-trip accessibility improves as higher-altitude roads open.
Summer (June-August) allows combining hot springs with hiking, mountain biking, and other outdoor activities. While sitting in hot water seems less appealing at 85 degrees, many Colorado hot springs cool their pools slightly in summer, and evening soaking under star-filled skies provides lovely experiences. This season sees the heaviest crowds.
Fall (September-November) delivers spectacular aspen color, pleasant weather, and fewer visitors than summer. September and October rank among the best months for balancing good weather, fall colors, and manageable crowds.
Local insight: Many Colorado hot springs enthusiasts prefer the shoulder seasons, particularly October and March/April, when you get good weather, reasonable crowds, and dramatic seasonal transitions.

Planning Your Colorado Hot Springs Adventure
Location Strategy: Colorado’s hot springs cluster in several regions. Plan your base location around other activities, then visit nearby hot springs. Glenwood Springs works well for I-70 travelers. Pagosa Springs serves Southwest Colorado explorers. Steamboat Springs combines hot springs with skiing. Ouray provides access to the San Juans.
Reservations: Increasingly, Colorado hot springs require reservations, particularly during peak times. Strawberry Park, for example, opens reservations 25-30 days in advance and books quickly. Call ahead or check websites before driving long distances.
What to Bring: Swimsuit (required most places), towel, water bottle, flip-flops, and a change of clothes. Many facilities provide towel rentals. Waterproof bags protect electronics. Sunscreen matters even in winter due to altitude and reflection off snow.
Timing: Visit weekdays when possible to avoid crowds. Early mornings or evenings typically see fewer guests than midday. In winter, aim for clearer weather when mountain views aren’t obscured by storms.
Elevation Awareness: Many Colorado hot springs sit at 7,000-10,000 feet elevation. The combination of altitude, heat, and mineral water can cause dehydration and dizziness. Drink extra water, limit soaking time initially, and allow a day to adjust to altitude before extensive hot springs sessions if arriving from sea level.
Driving Distances: Colorado’s size means hot springs are spread out. Glenwood Springs to Pagosa Springs requires 5+ hours. Steamboat to Ouray takes 5+ hours. Plan realistic road trip distances, particularly in winter when mountain passes require careful driving.
Combine Activities: Hot springs pair beautifully with skiing (Steamboat, Glenwood), hiking (Mount Princeton, Ouray), wine tasting (Palisade near Glenwood), historic mining towns (Silverton near Ouray), and scenic drives (Million Dollar Highway through Ouray).
The Verdict: Why Colorado Hot Springs Matter
In a world increasingly dominated by screen time and urban living, Colorado hot springs offer something remarkably grounding. You’re soaking in water heated by the earth itself, surrounded by mountains older than human civilization, absorbing minerals that have been underground for millennia. This isn’t a spa treatment someone invented last year. It’s a connection to geological processes operating on timescales that dwarf human concerns.
The Utes understood this centuries ago. They traveled considerable distances to reach healing waters, recognizing benefits that extended beyond simple relaxation. While we now understand the science (improved circulation, muscle relaxation, mineral absorption through skin), the essential experience remains unchanged. Hot mineral water makes you feel better. Mountains restore perspective. The combination creates something close to necessary in modern life.
Colorado’s particular gift is variety. Want luxury? Pagosa Springs delivers. Seeking authenticity? Hike to Conundrum. Need family-friendly convenience? Glenwood Springs obliges. Craving rustic mountain atmosphere? Strawberry Park awaits. This diversity means almost everyone can find their ideal Colorado hot springs experience.
The seasonal variation adds another dimension. Each visit delivers different experiences based on weather, temperature, crowds, and surrounding landscape. Winter snows, spring runoff, summer warmth, and fall colors transform the same pools into new experiences across the calendar year.
So yes, Colorado has world-class skiing, spectacular hiking, charming mountain towns, and stunning scenery. But the hot springs might be the state’s most distinctive feature. Where else can you soak in naturally heated mineral water at 10,000 feet elevation, surrounded by 14,000-foot peaks, watching snow fall or stars emerge depending on season? This specific combination exists in Colorado more accessibly than almost anywhere on Earth.
The hot springs aren’t going anywhere. The same geothermal forces that created them will continue heating groundwater long after we’re gone. But your ability to experience them exists right now. The drive into the mountains, the moment you slip into perfectly heated water, the mountain views that remind you how small your daily stresses actually are, and the feeling of genuine relaxation that settles in after 20 minutes of soaking. That’s available. The question is simply when you’ll make the journey to experience it.
The mineral water is hot. The mountains are waiting. The only question is which Colorado hot spring you’ll visit first.
