Suanbo Oncheon Resort

Suanbo Oncheon Resort is located in Chungju, North Chungcheong Province, South Korea, in the Suanbo hot spring district — one of Korea's oldest and most established natural hot spring resorts, whose high-temperature alkaline waters (emerging at 53°C) have been documented for bathing use since the Goryeo dynasty and designated as a national spa district by the South Korean government. The oligomineral thermal waters here are strongly alkaline and mineral-rich, with a long tradition of bathing for physical relaxation and skin comfort, and the Suanbo district has developed a comprehensive spa infrastructure of hotels, bathhouses, and wellness facilities serving both domestic and international visitors. Set in the scenic Woraksan National Park highlands, Suanbo Oncheon combines the deep bathing heritage of one of Korea's most historically recognised natural hot springs with the mountain beauty of one of Korea's oldest protected natural areas.
