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.

Located in Gongju-si, Gongsanseong Fortress is a mountain castle which was established during the Baekje Period (234-678). The castle is about 2.5km long, and there are two ways of touring the castle. One way is to start from the parking lot, pass the west gate, Geumseoru, and walk along the cement road. The other way is to turn left at the beginning of the cement road and walk along the top of the castle, which is called Sanseong Road. The cement road is very smooth and you can walk along it comfortably. On the other hand, Sanseong Road has many twists and the passage is narrow, but it has the advantage of following along the Geumgang riverside.When you begin the tour, the first site that you will meet is the Gongbukru, in front of the Sanseong village. From Gongbukru, follow the Sanseong Road, go over a low hill, and you will see Yeongeunsa, a small temple built in the 4th year of King Se-Jo’s reign. In front of the temple is Manharu and Yeonji, and this place is probably the most elegant out of the whole fortress. Enjoy the breathtaking view of the Geumgang riverside right here. Follow the trail path a little further up and Imryugak Pavilion appears, known as the largest of its kind within the fortress. You can glimpse a view of Geumgang River, but the trees may obstruct the open view of the scenery.It is worth the visit for its historical and cultural significance, and also for the beautiful view Geumgang riverside and the castle’s trail. The whole course is about 3 km, and 110m high, and so if you travel at a leisurely pace, it will take you about 2 hours and 30 minutes.

As one of the best sights in Geojedo Island, Geoje Haegeumgang River is called the Geumgang River (Sea Diamond) of the South Sea. As a rock island, Haegeumgang River belongs to Hallyeo Marine National Park, which is assigned as an official green area in South Korea.

These days it is known as Haegeumgang River, meaning Geumgangsan Mountain in the sea.The most stunning scenery of Haegeumgang River is the sunset and sunrise and can be best viewed on Ilwollbong Peak or Lion Rock. There is Shipjagul Cave in the center of Haegeumgang River, which is 100m long from east to west and 180m long from south to north. It has been called Shipjagul (meaning ‘cross’ in Korean) Cave because it looks like a cross when viewed from the sky. If you go on the tour, you will be fascinated by the x_height of the rock walls and the inside of the cave. A long time ago, scholars expressed their yearning for the beauty of nature by writing and reading poems they wrote on sailboats with a bowl of makkoli (rice wine) in their hands.When you take a ship around the island, you’ll be fascinated once more because of the great works such as the Maitreya Rock, which reflects on Eunjin Maitreya, Candlestick Rock and the 1,300 year old guardian pine tree of Haegeumgang River.
