A day at the Glenwood Hot Springs is not just a day at a pool. It's a day at the place that the Ute called Yampah — Big Medicine — for thousands of years before there was a town here. It's a day where Doc Holliday came to die, where Theodore Roosevelt came to hunt, where the Navy ran a wartime hospital. The water is the same water that's been coming out of the ground at 122°F for as long as anyone has been counting. Here is how to spend the day in it, and what you should know about what you're soaking in.
The pool sits in a wide flat at the bottom of Glenwood Canyon, where the Roaring Fork River meets the Colorado. From the highway you can see the steam rising off the water in winter, white and dense against the snow on the canyon walls. The first thing that surprises most first-time visitors is the sheer scale — the Grand Pool is over two city blocks long, 405 feet by 100 feet, holding more than a million gallons of mineral water. People talk about it as a pool. It is closer in scale to a small lake.
The water comes from a single source spring — the Yampah Spring — which the resort still pumps directly from. It comes out of the earth at 122°F, fast enough to fill the entire Grand Pool every six hours, and is cooled by exposure to the air down to between 90° and 93°F before it reaches the swimmers. There is a second pool — the Therapy Pool — where the water is cooled less, to 104°F, and held for soaking. Together the two pools have been the center of the resort since 1888.
Five Things You Should Know.
The Ute people were the original keepers of these waters, and used them for healing rituals for hundreds of years before any settlers arrived. They named the source spring Yampah, which translates roughly as "Big Medicine." The name is still used today — the Yampah Source Spring, the Yampah Mineral Baths, the Yampah Spa Vapor Caves down the road. The water itself contains fifteen minerals, including potassium, sodium, calcium, magnesium, and lithium — and the Ute were aware of its therapeutic properties long before anyone had a name for any of those elements.
The gunslinger of OK Corral fame — John Henry "Doc" Holliday — arrived in Glenwood Springs in May 1887, hoping the mineral waters could ease his advanced tuberculosis. He spent the last 57 days of his life in town. On November 8, 1887, he asked for a glass of whiskey, drank it, looked down at his bare feet, said "This is funny," and died. He was 36 years old. He's buried up the hill in Linwood Cemetery; the Doc Holliday Trail leads from town up to his grave, and visitors leave whiskey bottles at the marker. The springs didn't save him. But they may have given him a few more weeks of comfort than he would have had elsewhere.
President Theodore Roosevelt came to Glenwood Springs in 1905 for a six-week bear-hunting expedition. He stayed at the Hotel Colorado — steps from the pool — and the press of the day called the hotel "the Little White House of the West." His party bagged ten bears on that trip; Roosevelt is credited with six. According to legend, on a separate hunting trip in Mississippi, Roosevelt refused to shoot a bear cub that had been trapped — and a Brooklyn candy shop owner named Morris Michtom started making stuffed toy bears in honor of the president, calling them "Teddy Bears." The Hotel Colorado claims its share of credit, with hotel maids said to have made the original bear from scraps of cloth and given it to Roosevelt's daughter at the hotel.
From July 1943 to 1946, the Hotel Colorado and the Glenwood Hot Springs pools were leased by the U.S. Navy and run as a convalescent hospital — formally, the U.S. Naval Convalescent Hospital. Wounded sailors and soldiers came here from the Pacific and the European theaters to recover; the warm mineral water of the springs was used as a therapeutic tool. Over 6,500 patients passed through during the wartime period. The hotel was essentially stripped bare to meet sanitary requirements. The Navy returned it to its civilian operators in 1946.
The Yampah Source Spring produces over 3.5 million gallons of mineral water every single day, year-round, regardless of weather or season. The water emerges at 122°F — hot enough to scald — and is cooled before reaching the pools. The flow has remained essentially constant since the resort opened in 1888. There is no way to "use up" the spring. The water that fills the Grand Pool every six hours has been cycling through the earth for somewhere between several decades and several thousand years, depending on which hydrological model you trust. You are bathing in geological time.
How to Spend the Day.
The pool opens at 9 AM most days and closes at either 9 or 10 PM depending on the season. The right move is to arrive when the doors open, around 9 AM, when the Grand Pool is at its quietest and the steam is still rising in the cold morning air. Buy your day pass at the entrance — adult tickets run $38–55 depending on day of week and season — and head straight for the locker room. Lockers are free and included with admission. Towels rent for $4 or $5 (pack your own to save).
Start in the Grand Pool. The water at 90–93°F is warm enough to be comfortable but cool enough that you can actually swim in it without overheating. The far end has a lap lane and a diving board. The middle is for floating, drifting, and watching the canyon walls. Spend forty-five minutes here.
Then move to the Therapy Pool. At 104°F, this is the soak. New therapy jet chairs and power shower clusters provide upper-body massage; submerged benches let you sit and let the heat work. Twenty minutes here and your shoulders unclench in a way they probably haven't in months. After that, alternate — back to the Grand Pool to cool off, then back to the Therapy Pool. The contrast is the whole point.
The New Yampah Mineral Baths.
The resort recently expanded with the Yampah Mineral Baths — five smaller pools at varying temperatures, designed for a different kind of soak than the big pool. There's an infinity-edge pool with mountain views, a waterfall grotto where you can stand under falling water for a natural shoulder-and-neck massage, and two cold-plunge pools (Inhale at 52–60°F, Exhale at 75–80°F) for contrast therapy after a hot soak. If you've never done cold plunge before, this is a forgiving place to try. Twenty seconds in Inhale, then back to a warm pool. The endorphin response is real and immediate.
The first time I went under the waterfall in the grotto, I stayed there for ten minutes without realizing it. Time does something strange in hot mineral water.
Lunch, Then Back In.
The genuinely useful thing to know about a day at the Glenwood Hot Springs is the hand stamp policy. You can leave the pool, get a hand stamp at the gate, walk over the bridge into downtown, eat lunch, and come back without paying again. Use this. Lunch at Slope & Hatch — the taco-and-hot-dog spot at 208 7th Street, ten minutes' walk from the pool — is the right play. Or Sweet Coloradough for a sandwich and a donut. Then back across the bridge for the afternoon soak.
The afternoon and evening sessions are quieter than mid-day. The mid-day rush is the busiest stretch — families, day-trippers from Denver, the lunchtime crowd. After 4 PM, the energy shifts. The pools settle. By dusk, the steam off the water in winter is its own light show.
The Splash Zone (For Kids).
If you have kids, the Sopris Splash Zone is the answer to "but is there anything for them?" — yes, plenty. Shoshone Chutes is a tube-ride river designed to mimic a Glenwood Canyon whitewater rafting trip; the walls are made to look like the rock formations a few miles upriver. There's a splash pad, a kids' wading pool, an interactive fountain show, and mini-water slides modeled after Hanging Lake. It runs in summer and through fall as weather permits.
The Yampah Vapor Caves.
If you want to add something genuinely unusual to your day, the Yampah Spa & Vapor Caves are about a five-minute walk from the pool. These are natural underground steam caves — geothermally heated chambers cut into the rock, where the same mineral water that fills the pool emerges as vapor. You sit in the caves on a marble bench, the temperature is around 110–112°F, the humidity is essentially 100%, and you sweat. The Ute used these caves for healing rituals; today they operate as a spa with massage and treatment add-ons. There is nothing else like it in North America.
By the Numbers.
The Glenwood Springs Day, Done Right.
If I had one day in Glenwood Springs and the goal was to do the hot springs properly, here is what I would do.
Arrive on the California Zephyr from Denver at 2 PM. Walk across the pedestrian bridge from the Amtrak station — five minutes — to the Glenwood Hot Springs Resort. Check into the Hotel Colorado for the history, or the Hotel 1888 for the proximity. Take a forty-five-minute first soak in the Grand Pool to wash off the train. Walk into downtown for an early dinner at The Pullman or Riviera Scratch Kitchen. Walk back across the bridge to the pool for a long evening soak — under the stars in summer, under falling snow in winter — until the pool closes at 10 PM. Sleep deeply.
Morning: complimentary breakfast at the hotel. One more soak. Walk to Sweet Coloradough for a coffee and a donut. Catch the eastbound Zephyr at 5:30 PM back to Denver. Two days, no driving, more therapeutic value than most week-long vacations.
The Ute called this water Big Medicine. Spend a day in it and you'll understand why.
