The National Gongju Museum's special exhibition gallery hosts 'Gyeryongsan, Korea's Sacred Mountain' from September 22, 2026 to March 1, 2027. The Ministry of Culture's official listing says Tuesday–Sunday 09:00–18:00, closed Mondays, free admission. Gongju Museum is best known for its Ungjin Baekje collections, while this distinct exhibition focuses on Gyeryongsan's natural setting, heritage and the meanings people have attached to the mountain over time. It is an indoor museum show in Gongju, not an entry pass or guided hike in Gyeryongsan National Park. Some separate lectures or classes may require registration even though exhibition admission is free. Address: 34 Gwangwangdanji-gil, Gongju, Chungnam; phone 041-850-6300. Check temporary closures and any changed hours before visiting.
