Resort and Hotel – Only in Korea, the Former Lava Flow Turned into a Cave this Cool. This is amazing, in Korea there are caves formed from the former flow of volcanic lava.
Jeju is a volcanic island which is 130 kilometers from the Korean Peninsula. On this island there is an elongated tubular lava flow system. This is not a former mine tunnel but a natural channel from the magma of a volcano that has now been empty and forms a vast space, making it one of the largest caves in the world.
Because of its unique origins, the cave has become a research site for scientists and not only is this cave also one of the popular tourist destinations there. There are many alleyways in the cave, but what is most impressive is the Geomunoreum Lava Tube System formed by basaltic lava flows when the Geomunoreum volcano erupted around 200-300 thousand years ago.
Geomunoreum Mountain has a height of 456 meters and lava eruption flows as far as 13 kilometers to the coast. On its way to the beach, this lava creates many lava tubes and the Manjanggul Lava Cave Cave is the largest cave in this system. This cave stretches as far as 8,928 meters with a depth of 30 meters and 23 meters high.
Like the former lava flow, the interior of the cave does not have stalactites and stalagmites typical of limestone but is decorated with colorful carbonate decorations that form lava columns, lava bridges, cave corals, to beautiful shelves. In one of the last aisles that tourists can visit, there will be a huge lava column formed from molten lava that spills from the top to the lower area. This column stands 7.6 meters high and is the largest lava column in the world.
This lava cave is also home to 30,000 humpbacked bats that live in tubes and form the largest colony in Korea. In addition, 38 cave species have also been identified as living in the cave, most of them are Jeju spider caves. Curious to explore this cave? Stop by Jeju Island when visiting Korea.
