Cave · Nature / Park
A 30 m tall (98.5 ft) and 23 m (75.5 ft) wide lava tube penetrating more than 13 km (8 mi) into the earth, Manjanggul Cave makes up part of a World Heritage Site sheltering exceptional volcanic rock formations and wildlife. Observe the world's largest lava column standing 7.6 m (25 ft) tall, and a stone shape resembling Jeju Island. Part of a larger lava tube system, the cave features the greatest number of living creatures of all tubes on the island, including bats and the Jeju cave-spider. Formed 200,000-300,000 years ago, the tunnel remains remarkably well-preserved with lava stalagmites and stalactites and cascades of funky flowstones. Watch the slippery steps and dress for 10 C (50 F). Add Manjanggul Cave to your Jeju travel itinerary, and discover new vacation ideas by using our Jeju online journey planner.

  • We went here right as we landed, it was a fun way to get moving after sitting on the plane for a couple of hours. Really enjoyed this cave experience.  more »
  • Very cool trip and 2km walk underground in the lava tube. Largest in the world. It is dark, cool and damp. The walking surface is cooled lava, so I'd recommend appropriate footwear. The lighting is...  more »
  • Walking through the lava tubes is just an amazing experience. It is surreal and beautiful to see what millennia of lava flow has created. One of the best places to see on Jeju Island.  more »
  • Very beautiful place. Well managed, clean and not challenging for a any person who can take a walk in a park. There are a few steps you got to take on to get down into the cave, but once there, it's all worth it...just mind your step, and your head a bit (but not really). It's a very comfortable walk down in the cave. Nice ambient vibes.
  • Classified as a UNESCO heritage site, this is an amazing must-see attraction on your trip to Jeju. The entire length of this lava tube is about 15km but 1km is open for public. You can see many lava rock formations, stalactites and stalagmites as well as lava textures on the floor of the cave. It is relatively an easy walk but not suitable for wheelchairs.
  • Excellent experience. It was drizzling that day but it was worth the trip. Informative and interesting. The floors are pretty uneven and it was quite difficult to walk. Not stroller friendly, so do carry your toddlers. It can get quite cold inside and, wet and slippery. So wear covered shoes. But 2 year old enjoyed the trip and was amazed at the various rock formations.
  • Pretty darn large cave. Very pretty FYI. If using public transport, the shuttle service to the nearest town is twice per hour so be careful not to miss them like I did. I waited around just over an hour to get back to my hotel.
  • It’s chilly inside and I felt the “chill” and thrill of being in an ancient lava tube. I kept imagining that long Tina ago a molten rock was flowing through this lava tube, leaving behind an intricate structures for us to understand more about earth. Don’t skip to walk to the end, the lava stalagmite is so huge and mesmerizing, it’s almost eerie feeling just to look and gaze upon it.
