Woori Yuhwang Spa is a sulphurous hot spring facility in South Korea, offering traditional Korean bathing in waters characterised by hydrogen sulphide content prized within a long thermal tradition for the comfort they leave on the skin and for muscular relaxation. The sulphurous waters are among the more mineralogically potent available in South Korea and attract visitors specifically seeking the distinctive character of this water type. The spa continues the longstanding Korean cultural tradition of well-being through mineral-rich natural spring waters.
Insider tip — Woori Yuhwang Spa in eastern Seoul draws sulfurous deep groundwater at 38°C, one of the few genuine mineral hot springs operating within the city limits. The traditional Korean jjimjilbang atmosphere — heated jade rooms, salt saunas, and communal bath halls — offers a genuine respite from the urban pace. The location in Gwangjin-gu places it within easy reach of the Han River cycling paths and Achasan hiking trails. Late-night soaks after exploring Hongdae or Myeongdong are a local favorite.
