The World’s Only Location Holding UNESCO’s “Triple Crown” Designation

Jeju Island is an oval-shaped island about 73km long from the east to west and 41km from the north to south. At the center of the island, Halla Mountain rises 1,950m above sea level, making it the highest point in South Korea.
This volcanic island has a varied and unique volcanic topography, which makes the entire island a volcano museum. More than 360 large and small oreums1) and over 160 lava tubes are distributed throughout the island. It is rare for such a small island to have so many oreums and lava tubes.
