About Castle Hot Springs
Castle Hot Springs is a developed hot spring pool in Yavapai County, Arizona, about 13 miles southwest of Black Canyon City, AZ. The nearest large city is Deer Valley, AZ, roughly 25 miles away as the crow flies.
The temperature at the source has been recorded at 115°F (46°C). That puts it in the "too hot to enter at the source" range. Water this hot can burn skin quickly. Soaking pools are usually cooled by mixing with creek or tap water. Never enter the source itself. At developed sites the soaking pools are normally cooled to a comfortable level, so the pools you sit in will be cooler than this figure.
This is a developed site with built pools, tubs or a bathhouse, so there is usually an entry fee, set opening hours and basic facilities.
The site has 2 mapped pools or sources within about 500 meters of each other.
This spring comes from the US federal Thermal Springs List compiled in 1981. Nobody has confirmed it on the ground for this directory since, so treat the details as historical. Many springs on that list sit on private ranch land, so never visit without permission.
