Manjanggul Cave is the largest known lava cave in the world.
Manjanggul Cave, Created when Jeju’s Hallasan erupted hundreds of thousands of years ago, it measures 5 meters in width, and more than 13,000 meters in length.
This massive lava tower, a rare characteristic of lava tubes, was formed when the upper flow tube cracked and poured the molten rock to the lower level.
It is appointed as Natural Monument No.98, and is a unique underground attraction.
There are many caves located throughout the country.
On Jeju Island alone, more than 120 lava caves exist.
Among them, the array of caves at Geomun Oreum (parasitic volcano) are some of the best in the world.
The lava that flowed from Geomun Oreum created 13 kilometers of lava tubes – the Manjanggul, Bangdwi, Gimyeong, Yongcheon and Dangcheomul lava tubes.
Among these only Manjanggul is open to the public, and only partially too.
Manjanggul Cave is a 7.4-km lava tube.
It is an internationally-known large cave at 18m-wide and 23m-high.
There are lots of lava tubes in the world.
The one which is hundreds of thousands of years old as well preserved as Manjanggul is rare.
Manjanggul has three entrances created by sinkholes. Only the second entrance and 1km of the cave is open to the public now.
Inside the cave, there are various lava tube structures including lava stalactites, and lava-stalagmites.
The 7.6m lava column at the end of the public section of the cave is the largest of its kind in the world.
About 8 kilometers long,
the tube retains a yearly average temperature ranging from 15 to 18 degrees Celsius and 87 to 100 percent humidity.
In 1962, it was designated as natural monument No. 98. Inside, the tracks where the lava flowed(200,000 to 300,000 years ago) can still be seen.
One can also see geomorphological features such as the world’s largest, 7.8-meter high, lava column.
Other features exist inside but the public can only view up to the column. One can also spot rare red owls in the cave.
The red owl is also listed on the International Union of Conservation of Nature’s 2007 Red List of Threatened Species.
