Even early Arizonans knew a resort when they spotted one.
For centuries, members of the Yavapai and Apache tribes luxuriated in the piping-hot, therapeutic waters of a site now called Castle Hot Springs north of the Valley near Lake Pleasant. More than 200,000 gallons of 120-degree water gurgles from the earth each day at the base of rugged and remote southern Bradshaw Mountains. Native Arizonans would soak their bones and bask in the healing properties of the mineral-rich, pure thermal waters.
