Manjanggul Cave (만장굴 (제주도 국가지질공원) in Jeju, South Korea, is one of the most beautiful lava tunnels in the world. It has been designated as a Natural Monument.

Manjanggul Cave has a variety of interesting structures including one of the biggest lava stalagmites in the world. The cave is 13km long, making Manjanggul cave one of the longest lava tunnel in the world. However, only 1 km is open for visitors.

It is one of the largest lava tubes in the world having a passage with a width of up to 18m and a height of up to 23m. Numerous lava tubes are found worldwide, but Manjanggul lava tube is an outstanding example because it has well preserved passage and features despite its very old age.

We absolutely loved our visit of Manjanggul Cave. This sight was one of our highlights on Jeju island.

The Manjanggul Cave is around 200 to 300,000 years old. It was formed by the flow of lava, cooled during the eruption of the Geomunoreum volcano.

It has been discovered in 1947, then partially visited in 1976. Part of the site has now been classified as a UNESCO World Heritage Site since October 9, 2015.

The interior of the tunnel maintains a temperature of 11 ~ 21C degrees, which can be very pleasant during the heat of the summer.

Tips: since it can get a bit cold in the cave, we strongly recommend to bring a small jacket/hoodie during your visit.

Also we recommend to wear good shoes (no flip flops) as it’s very rocky and wet along the way.

Manjanggul cave is lcoated in a nice park which you can also visit on the way to the entrance of the cave. You will then be mesmerized at the sight of a figure carved out of volcanic rock, the dolharubang, standing in front of the entrance to the Manjanggul.

As you enter the cave, you can realize how big it is and how impressive it is. You will suddenly feel a drop of temperature as low as 10 ° C the deeper you go.

There is only 1 way inside the cave and you need to get back using the same path. During your visit you will see many interesting rock formations. One of the highlight is the Stone turtle an astonishing lava formation outlining Jeju Island. It is actually called a Lava raft. It is a remnant of rock rubble that was carried down flow by a lava flow. Eventually it solidified.

The tunnel itself shaped by the lava flow is simply gigantic. You can only image what it would have been like during the eruption and the power of the volcano. At the end of your visit inside the tunnel you can see an incredible lava column measuring 7 m in height. It is the largest lava column in the world! Its formation came from a huge amount of lava, poured between the two levels of the covered passage.

In Manjanggul Lava Tube, large and small passages occur repetitively, it is not all regular in terms of height and width. Continuous supply of hot lava into the tube caused thermal erosion of the tube’s floor resulting in the irregular size. Sometimes the height of the cave reach 23meters high. It’s really impressive.

Another particularity of the cave is the lave flowlines. When lava flows in a tube the level of the flow is often recorded on the walls. These features are called Lava flowlines. Many flowlines can be found inside Manjanggul.

The cave also has some animals living inside. Manjanggul cave shelters an impressive colony of bats. According to statistics, more than 30,000 specimens have made their home there. In addition, at least 38 other species have been discovered near the caves. But don’t worry, we didn’t see any and didn’t feel scared at all during our visit.
