Manjanggul Lava Tube [National Geopark] (만장굴 (제주도 국가지질공원)) Visitor Guide with Practical Tips

Arriving at Manjanggul Lava Tube (만장굴) on a sunny day, I was immediately struck by the coolness that enveloped me as I stepped into the cave. The contrast between the warm weather outside and the natural chill inside was refreshing. This UNESCO World Heritage Site on Jeju Island showcases the impressive geological features formed over 100,000 years ago, making it a worthwhile stop for any nature enthusiast.

What makes Manjanggul Lava Tube worth visiting?

The Manjanggul Lava Tube is one of the longest lava tubes in the world, stretching about 7,400 meters. However, only a kilometer is open to the public, which includes some fascinating lava formations like stalactites, stalagmites, and stone pillars. The highlight is a massive stone pillar that stands at 7.6 meters tall, which is recorded as the largest in the world. Honestly, it’s hard to appreciate the scale of these formations until you see them in person.

This site not only provides visual splendor but also serves an important role in geological studies and conservation efforts. The well-preserved conditions within this lava tube make it invaluable for scientists exploring volcanic activity and formations. Just be aware that most of the cave is closed off to protect its integrity, so you won’t get to explore it all. I found that pretty refreshing.
