Cottonwood Hot Springs is located near Buena Vista, in the Colorado Rockies. The sulfurous, slightly acidic water (pH 6.5) reaches around 42 °C (108 °F). The site offers an indoor bath, a rotenburo-style outdoor bath, a sauna and massage.
Insider tip — Cottonwood Hot Springs sits at 8,700 feet elevation in the Arkansas River Valley near Buena Vista, drawing sulfurous geothermal waters from beneath the Collegiate Peaks. The rustic resort dates to the 1880s silver mining era, and its historic stone tubs and wooden cabins retain an authentic frontier atmosphere. At this altitude the mineral pools offer dramatic views of 14,000-foot peaks including Mount Yale and Mount Princeton. The sulfurous waters are especially restorative after hiking or mountain biking in the surrounding San Isabel National Forest.
