El Dorado Hot Springs is owned by Camilla Van Sickle and Bill Pennington. It's a 1,200-gallon-per-minute subterranean hot spring of odorless, tasteless mineral water, with no nasty chemicals. Just a hot tub the way nature intended it. The water has a natural pH of 8.2 and contains sodium, calcium, potassium, magnesium, chloride, bicarbonate, sulfate, silicates, fluoride, boron, and trace amounts of lithium, which does wonders for the hair and skin.
Soak away your hectic workweek in one of the many pools, some of which have retractable shade or misting systems. You can choose either private soaking areas, or semiprivate, and if you decide you don't want to come back to the grind right away, there is an on-site sleeping cabin called Motel California that has a full bath and linens and comes with various soaking packages. It's a steal at $50 to $65. Therapeutic massage and Tibetan Bowl Resonant Relaxation are available by appointment.
