Insider tip — Samseong-oncheon sauna in the Yeosu coastal zone taps a sodium-chloride spring enriched by the region's proximity to the South Sea. Operating around the clock in classic jjimjilbang style, the facility offers multiple heated rooms and communal pools at 40°C. The saline mineral content is reputed to improve skin hydration, making it popular with locals after a day on Yeosu's island-hopping ferry routes.
