A walk around a spa town

The Czech town of Karlovy Vary is home to over a dozen hot springs, all revered for their healing properties

You must have a sip," the guide insists, in a gentle but persuasive tone. The sip in question is from a thin shooting geyser around which is built a wide, shallow basin, enveloped in warm steam. In the bright afternoon sun, falling droplets and steam from the geyser catch the light rays and convert them into rainbows that vanish as quickly as they appear. Any lingering doubt about the nature of the spring is swiftly dispelled by the distinct sulphurous smell that hangs in the air. A changing tableau of people approach the spring, fill tiny, fist-sized juglets from the geyser, chug it and move on. How bad can it be, I think to myself and follow suit—and promptly gag.

The water is metallic, acrid and vile. Yet, in the Czech town of Karlovy Vary, about two hours west of Prague, more than a dozen hot springs (as well as 300 smaller ones), are revered as the springs of health, wellness and longevity.

Known locally as Karlsbad/Carlsbad, Karlovy Vary (literally Charles' spring) was a European spa town for centuries before Czechia got swept behind the Iron Curtain. It is named after Charles IV, the 14th-century Roman Emperor and king of Bohemia.
