Mount Princeton Hot Springs

Mount Princeton Hot Springs near Nathrop, Colorado, is one of the Rocky Mountains' largest and most dramatic hot spring resorts, where silica-rich geothermal water flowing from the Chalk Cliffs — brilliant white travertine formations stained by mineral precipitation — at over 40°C feeds developed pools and natural creek pools at 8,000 feet elevation with direct views of 14,197-foot Mount Princeton. The natural creek flowing through the resort property mixes cold Arkansas River tributary water with the hot spring outflow to create multiple temperature zones where bathers move between scalding natural pools and the main resort's developed facilities at the foot of the Chalk Cliffs geological feature. Colorado's natural hot spring scene reaches one of its scenic peaks at Mount Princeton, where the vertical relief from the Arkansas River valley to the Collegiate Peaks' summits creates a backdrop of American mountain grandeur rarely equaled at any thermal destination.
