Before the days of jetted tubs, spas, and heated pools, the only real place to soak in hot water not in
your bath tub was to visit a geothermal hot spring. Although not an option for some, you might be surprised to learn that you live closer to a hot spring than you think. In fact, there are hot springs on every continent produced by superheated groundwater pushed to the surface by the extreme heat from the Earth’s core. So pass on what is likely a coal-powered soak and visit one of these classic all-natural spring-fed soaks.
