Castilla Springs
Castilla Springs comes out hot, comfortably above a bath, about six miles from Mapleton. A 1967 analysis shows the water loaded with dissolved minerals, salty, with sulfate and chloride high. No owner and no public access status appear in the record, so whoever manages it today is unknown here. Utah County is where it sits, with Diamond campground close by.
A short walk of five hundred feet or so separates the spring from the road, and that road carries no name on file. Winter is serious in this corner of Utah: six feet of snow most years and close to twenty inches of precipitation. Diamond campground is under six miles off.
December to February is the window the record gives, though with that much snow the short walk may be in drifts. The water is above 100 degrees, so lower yourself in gradually. Nothing on file confirms public access. The mineral reading is nearly sixty years old. No fee is mentioned.
The water at Castilla Springs is slightly alkaline (pH 7.9) with 6610 mg/L total dissolved solids. It is notably rich in calcium (may support bone density and joint health), magnesium (known for muscle relaxation and stress relief), and sodium (supports circulation and skin hydration).
