JEJU Island

Jeju Island, or Jejudo, is an oval-shaped volcanic island measuring approximately 73 kilometers from east to west and 41 kilometers from north to south. In the heart of the island stands Halla Mountain, a 1,950-meter mountain. Created entirely from volcanic eruptions, Jeju Island boasts a diverse and unique volcanic land form, so much so that the island itself could be seen as a ‘museum of volcanoes. ‘ On land, over 360 oreums (*Oreum refers to parasitic volcano in Jeju dialect) of varying sizes can be seen, while some 160 lava tubes are spread out across the island and are situated underground. It is extremely rare for so many oreums and lava tubes to be found all on a single island that is as small as Jeju Island.

As such, Jeju Island was designated as a Biosphere Reserve by UNESCO in 2002, a World Natural Heritage site in 2007, followed by a Global Geopark in 2010, proving its value by becoming the only place on Earth to receive all three UNESCO designations in natural sciences.
Jeju Island is now undisputedly a ‘treasure island of environmental assets’ for the whole world to appreciate and protect.
