Hantangang Global Geopark Center in Pocheon displays the geology, ecology, history, and culture of the Hantangang River, and it sits near Bidulginangpokpo Falls. Exhibits include columnar joints, pillow lava, and rocks formed by volcanic activity, shown through a 4D film and a digital experience hall. Admission is free, and visitors can touch the rocks while walking through the first- and second-floor exhibition halls. The center is small, so adults can find it dull.
