>> World Heritage Sites by UNESCO on Jejudo Island
Among all of Jeju’s natural wonders, three sites have been recognized as World Heritage Sites by UNESCO (2007): Hallasan Mountain, Seongsan Ilchulbong Peak, and the Geomunoreum Lava Tube System. Hallasan Mountain is perhaps Jeju’s most prominent geographical feature, rising out of the very center of the island. Seongsan Ilchulbong Peak has been recognized for its sedimentological characteristics and is one of the best places in the world to study Surtseyan-type volcanic eruptions. The third and final World Heritage Site is Geomunoreum Lava Tube System, one of the most extensive series of lava tube caves in the world.
