Hyeopjaegul Cave

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 width and 5m in 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.
