Dotsero Warm Springs
Dotsero Warm Springs flows at 90 degrees Fahrenheit along Eagle River corridor public lands, carrying extraordinary dissolved salts—nearly 5,800 milligrams per liter of chloride and 3,700 of sodium—making it one of Colorado's most saline thermal springs.
Water emerges just 23 meters from roadside in high-elevation terrain near Gypsum, with the Colorado River Valley unfolding to the west. Rocky, sparse vegetation dominates the arid landscape at 6,187 feet, where the spring marks a transition zone between river canyon and sagebrush plateau. Gypsum Campground along the Eagle River provides nearby camping access.
The spring sits immediately beside a pullout on the Eagle River corridor, offering effortless roadside access. Water chemistry is highly saline—unsuitable for direct contact without dilution. Gypsum Campground (first-come, first-served, May-November) lies 11.5 kilometers away with river fishing and hiking opportunities.
Dotsero's extreme salinity reflects circulation through ancient marine sediments deposited during Colorado's geologic past when shallow seas covered the region. The nearby volcanic crater and lava flows mark the area's complex geothermal and igneous history, linking surface thermal expression to deeper magmatic influences.
The water at Dotsero Warm Springs is neutral (pH 7.0). It is notably rich in calcium (may support bone density and joint health), sodium (supports circulation and skin hydration), and sulfate (traditionally used for skin conditions and inflammation).
