## About White Sulphur Springs (California)

White Sulphur Springs in Napa County sits less than a mile outside Saint Helena and was, by Wikipedia's account, the oldest warm mineral springs resort in Northern California, founded in 1852. No temperature is on file for the current record. The USGS sampled the water in 2004 and found it alkaline and mineral-heavy, with iron among the dissolved load. Access and ownership are not recorded.

A road passes within about 160 feet. The elevation is low, around three hundred feet, on the ground near the town. Rain runs to two feet or so a year, concentrated in winter, and snow is not a thing here. The nearest campground listed is fourteen miles off at Oak Shores, which the name says is for day use.

Founded in 1852 in St. Helena, White Sulphur Springs was regarded as Northern California's oldest warm mineral springs resort facility. The USGS maintains a sampling site there.

No best months are listed. Roadside access, so a look needs no walk. Because no temperature is on record you cannot plan a soak from this page; the 2004 chemistry is the most recent firm data. Ask in Saint Helena about the property's current status, since the record does not say what stands there now. No fee on file.
