Mercey Hot Springs is a private natural hot spring resort in the Diablo Range foothills of Fresno County, California, where chloride- and sodium-rich artesian water at around 38°C feeds outdoor soaking pools in a remote Coast Range valley accessible from the San Joaquin Valley. The resort, a beloved destination for Bay Area and Central Valley residents, offers a peaceful desert hot spring experience with accommodation in vintage trailers and simple cabins, embodying the California tradition of the informal outdoor hot spring getaway. The surrounding golden grass hills, blue oak woodland, and the extraordinary dark skies of the remote Diablo Range provide a characteristically Californian landscape setting.
