Castle Hot Springs in the Bradshaw Mountains north of Phoenix, Morristown, Arizona, is a historic luxury resort whose silica-rich geothermal waters were first developed in the 1890s to attract visitors escaping the desert heat to a cool mountain oasis at 2,000 feet elevation. The property — burned in 1976 and meticulously restored and reopened in 2018 — retains the intimate character of a classic Arizona dude ranch combining historic bungalows, pool gardens, and hot spring soaking with western horseback riding in the surrounding Tonto National Forest. Presidents Coolidge and Roosevelt, Howard Hughes, and John D. Rockefeller were among the 20th-century luminaries who sought recreational escape at this Bradshaw Mountain resort, giving Castle Hot Springs one of the most distinguished guest books of any American hot spring destination.
