Cottonwood Hot Springs emerges at an extraordinary 136 degrees Fahrenheit near Buena Vista, a scorching roadside spring in the San Juan foothills of Colorado that stands 98 degrees above ambient air temperature.
Water courses from bedrock fissures, flowing just 41 meters from the road into a setting of high-elevation terrain where mountain views frame the basin. The mineral-rich flow creates a thermal ecosystem within the snowbound landscape of Chaffee County at 8,683 feet.
History of Cottonwood Hot Springs
This spring's exceptional heat likely derives from deep circulation along regional fault structures. The Chaffee County geothermal system has supported local interest for generations, with the nearby Collegiate Peaks range lending geological context to the area's thermal activity.
Roadside access allows easy viewing from Cottonwood Pass Road. Spring water exceeds 136 degrees Fahrenheit—extremely hot and dangerous to enter. Visit in late spring through early fall when mountain roads are passable and snow has cleared from high passes.
