At Mystic Hot Springs in Monroe, Utah, hot water comes out from deep underground at a scalding 75 degrees degrees Celsius at a rate of about 200 gallons per minute. The water travels through a long channel, cooling as it flows, and distributed to various locations across the property. By the time it reaches the two concrete pools and eight vintage bath tubs, it was cooled to a comfortable 37-43 degrees. Hundreds of tourists come here to soak in the mineral rich waters.

The eight huge, claw-footed tubs are perched at the top of the hill from where one can have stunning views of the valley below. Each tub is cleaned and filled with fresh water daily, and the lower pools are refilled with fresh water once or twice weekly.
