Mount Princeton Hot Springs
15897 Co Rd 162, Nathrop, CO
Nathrop, CO
Warm mineral pools set right in the bed of a mountain creek, steaming below the pale slopes of a Sawatch Range fourteener.
Mount Princeton Hot Springs is a beloved geothermal spot in the Arkansas River valley, where naturally heated mineral water rises along Chalk Creek in the shadow of Mount Princeton, one of Colorado's fourteen-thousand-foot peaks. The most magical soaking is in pools built right into the creek bed, where hot springs mix with the cold mountain stream and you can dial in your own temperature by moving closer to or farther from the flow.
People have valued these waters for generations, and the site today blends those natural creekside pools with larger developed soaking pools. Set against the pale Chalk Cliffs and the high Sawatch peaks, it is one of the most scenic soaks in the state and a perfect way to unwind after a day in the surrounding mountains.
What Guests Love
- Soaking in warm pools built right into the boulders of a rushing creek
- The view up to the pale Chalk Cliffs and Mount Princeton itself
- A relaxing counterpoint to the valley's hiking and whitewater
- The mix of creekside natural pools and larger developed soaking pools
Worth Knowing
- The creekside pools depend on flows, which run high and cold in spring snowmelt
- The resort area is developed, so this is a comfortable soak rather than a wild backcountry spring
- It sits at high elevation, so hydrate and ease into altitude
- Summer weekends and holidays are busy, so an early or midweek visit is calmer

Learn about Mount Princeton Hot Springs
The waters and how they form
The hot springs here are fed by water that percolates deep into the earth, is warmed by the region's geothermal heat, and rises back to the surface along fractures in the rock near Chalk Creek. The result is mineral-rich water that emerges hot and mingles with the cold snowmelt of the creek, creating a natural gradient of temperatures.
The signature experience is the creekside soaking pools, ringed with stone, where the balance of hot spring water and cold creek water lets you find a comfortable spot. Because the creek runs high and cold with spring snowmelt, these pools shift with the seasons, and the surrounding resort also offers larger developed pools that soak comfortably year-round.
The Chalk Cliffs and Mount Princeton
Rising above the springs are the striking Chalk Cliffs, pale slopes on the flank of Mount Princeton that look like chalk or snow from a distance. They are not actually chalk but a soft, weathered rock stained light by the same kind of hot mineral waters that feed the springs, a geological signature of the geothermal activity beneath the range.
Mount Princeton itself is one of the Collegiate Peaks, a run of fourteeners in the Sawatch Range named for universities, that also includes Harvard, Yale, and Columbia. Together they form one of the highest and most concentrated groups of tall peaks in the Rockies, and the springs sit at their feet, a warm reward within sight of some serious mountains.
The history of the springs
The Ute people, whose homeland this valley is, knew and used the healing waters of the region long before the mining era. In the late 1800s, as prospectors and railroads pushed up the Arkansas valley toward the mining camps of the Chalk Creek canyon, the hot springs became a popular stop, and a grand resort hotel once rose here to draw travelers to its waters.
That first golden age faded with the mines, and the original grand hotel is long gone, but the springs endured and were developed again into the retreat that operates today. The valley around it is dotted with the ghosts of that mining past, including the well-preserved ghost town of St. Elmo farther up Chalk Creek, one of the best in Colorado.
The valley and its seasons
The Upper Arkansas valley is an outdoor playground, with the Arkansas River offering some of the finest whitewater rafting in the country, the Collegiate Peaks luring hikers and climbers, and hot springs to soak away the effort. The nearby towns of Buena Vista and Salida are friendly bases with good food and easy river access.
Summer is the busy season, warm and bright, ideal for pairing a soak with rafting or a peak. Fall paints the aspens gold across the range. Winter turns the valley crisp and quiet, and there are few pleasures quite like soaking in steaming water while snow falls on the surrounding mountains. Whatever the season, the pools stay warm and the peaks stay grand.
