Tongni Tantan Park sits near High1 Resort in Taebaek and uses a closed mine tunnel as its setting. Inside the old tunnel, the park has built "A Path Holding Memories" and "A Path Seeking Light," adding media art and music. The main building offers a live sketch based on the Gumunso Dragon Palace tale, an AR photo zone with animals from six continents, and a shooting game about saving Taebaek. The content is limited, so admission carries some burden.
