Crystal Crane Hot Springs, near Burns, Oregon, feeds its pools with iron-rich water at 38°C. The site includes an indoor bath and an outdoor bath, amid the wide-open landscapes of eastern Oregon.
Insider tip — Crystal Crane Hot Springs sits in the high desert of Harney County, Oregon, where natural iron-rich geothermal water fills a large pond and private soaking tubs on an off-grid ranch. The remote setting — surrounded by sagebrush, cranes, and vast silence — makes it one of the most atmospheric hot-spring destinations in the American West. Stargazing after dark is extraordinary given the near-zero light pollution. Primitive camping and rustic cabins let guests extend the desert immersion overnight.
