Thermo Hot Springs takes its name from the small hamlet of Thermo in Iron County, southern Utah, perched on the high desert plateaus of the Colorado Plateau country. The establishment draws on bicarbonate thermal water rising at a remarkable 60 °C with an alkaline pH of 8 — a chemical combination characteristic of the basaltic geothermal zones of the American intermountain West.

At 60 °C at source, the water is cooled before bathing, but the resulting heat remains deeply enveloping. The bicarbonate composition imparts a particular softness to the water, with that slightly alkaline, almost silky feel on the skin that devotees of alkaline springs recognise immediately. Against a backdrop of rust-red mesas and sagebrush flats in southern Utah, Thermo Hot Springs is an authentic geothermal stopover, well off the tourist trail of Zion and Bryce Canyon.

Insider tip — Thermo Hot Springs near Milford, Utah — a high-temperature geothermal spring (~138°F at source) in Iron County's Black Rock Desert. Named after the nearby unincorporated community of Thermo, which itself is named for the springs. The Escalante Valley has significant geothermal potential.
