Icheon Spa in Icheon city, Gyeonggi province, draws on deep bicarbonate alkaline springs at around 40°C that have been prized since the Joseon dynasty, when the royal court commissioned the first bathing facilities to be built here. Icheon is doubly celebrated in Korean culture — for its thermal waters and for its celadon pottery tradition, which was revived in the 20th century after being almost lost and today produces some of the finest blue-green glazed ceramic work in the world. Modern spa complexes in Icheon offer a range of thermal bathing experiences from traditional Korean jjimjilbang-style facilities to more internationally oriented wellness centres, all drawing on the same naturally warm mineral-rich water. The Gyeonggi landscape of Icheon, with its paddy fields, autumn foliage and proximity to Seoul, makes it a perfect day-trip or overnight destination from the Korean capital.
Insider tip — Icheon is South Korea's most celebrated spa city, historically supplying alkaline sodium-chloride hot water to Joseon kings who visited to treat skin ailments — the water is naturally soft and silky on the skin, locally called 'jade water.' Modern jjimjilbang complexes offer gender-separated soaking floors, heated clay rooms, and communal rest areas open 24 hours. Day-trip from Seoul Station (40 min by express bus) and combine a visit with Icheon's famous ceramics village.
