Odusanseong Fortress (오두산성) is built around the strategic summit of the mountain. Its walls stretch across roughly 620 meters and were built during the Baekje Dynasty. The fortress is built on the intersection of the Imjingang River (임진강) and the Hangang River (한강) on the summit of Odusan Mountain (오두산, 119 meters). The mountain’s slope is steep and stones used in the construction of the fortress walls are scattered here and there at the summit. These scattered stones are evidence that the fortress underwent repairs several times during the Samguk (Three Kingdoms) era and the Joseon Dynasty, as these stones were evidently quarried and used to mend the fortress walls. Excavations have discovered a great deal of earthenware, white porcelain, tile, and iron arrowheads. Topographically, the fortress sits on a prime strategic junction and the Unification Observatory has been situated there as well. The fortress stands as an important object of study concerning fortifications and structures from the Baekje Dynasty. It has been recorded on the stele of King Gwanggaeto, samguksagi (History of the Three Kingdoms), in the baekjebongi (Baekje Annals) and on daedongyeojido (Map of Korea) that the fortress was the Gwanmi Fortress of Baekje, attracting many scholars and researchers interested in this period.

Hyeopjaegul Cave (협재굴) is one example of the lava tubes of Jeju Island, along with Hwanggeumgul, Socheongul, Ssangyonggul and Manjanggul Caves. The cave is approximately 200m in length, 10m in x_width and 5m in x_height. It is thought to have been created by the lava that erupted from Hallasan Mountain some 25 million years ago. This cave uniquely contains features of both lava and limestone caves. The entire area surrounding the cave is a huge stratum of seashells and sand, while the interior of the cave has a mystical ambience due to its various lava formations such as stalactites and stalagmites, which hang from the ceiling and sprout up from the bottom of the cave. Stalactite columns that are formed when stalactites and stalagmites meet each other are also located throughout the cave, so the scenery is very unusual. The cave walls are covered in lime, which at times looks like beautiful cave paintings. The temperature inside the cave stays at 17~18℃ throughout the year, making the cave a welcome escape from the summer heat and a great place to keep warm during winter.The Hyeopjaegul Cave has been designated Korea’s natural monument No. 236 and ranks among the world’s other major mysterious caves, such as the stone salt cave of Peru and the underwater limestone caves of Yugoslavia. As the Hyeopjaegul Cave is close to the Ssangyonggul Cave (meaning ‘Two Dragons’) the two can be visited together on the same day.
