El Dorado Hot Springs sits in the open Sonoran Desert between Phoenix and Quartzsite near Tonopah, Arizona, drawing geothermal water at around 46°C from desert aquifers into a collection of private outdoor soaking tubs and communal pools. The facility operates clothing-optional and at night draws astro-photography enthusiasts for the exceptionally dark desert skies alongside the warm thermal water. The stark beauty of the flat desert surrounding the springs, with distant mountain ranges on the horizon, is characteristically Arizona.
