Even the Ancient Romans knew the joys (and the benefits) of sinking into a bubbling thermal bath and soaking in the mineral waters—starting from the Baths of Caracalla, Italians have maintained an enduring love affair with the many natural hot springs scattered across the country. As temperatures start to dip and the chill in the air gets stronger, a visit to a thermal bath might be the trick to ease you nicely into fall.

Nitrodi, Campania

The oldest spa in the world. Or so they say, having been established by the Ancient Greeks when they colonized the island of Ischia. The reputation for the thermal waters of Nitrodi made it a hot destination for treatment and relaxation between the 1st Century BC and 6th Century AD.
