Gyeryongsan Oncheon is a hot spring at the base of Gyeryongsan, a mountain in South Chungcheong Province of South Korea revered as a sacred site in Korean Taoist and shamanistic traditions and home to one of the country's most celebrated national parks. The geothermal waters emerging near this mountain are naturally heated by the volcanic and tectonic forces that shaped the Korean Peninsula's geology, and their proximity to a site of spiritual significance imbues the bathing experience with a contemplative and reverential quality. Visitors combine a soak in the therapeutic geothermal mineral waters with exploration of the mountain's ancient religious sites, hiking trails, and seasonal landscapes of exceptional natural beauty.
Insider tip — Gyeryongsan Oncheon on Geoje Island draws saline spring water from coastal geology, yielding soft sodium-chloride baths favored for easing muscle tension after outdoor activities. The facility is close to Geoje's shipbuilding coast, offering an interesting industrial-maritime backdrop. Evenings are quieter and the outdoor pools catch spectacular sunsets over the Korea Strait. Bring your own towel as amenity packages vary by season.
