Manjanggul Cave, Jeju

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.

If you're into your geological formations or simply just walking in an underground cave this is your place to go. Super cool getting to walk a kilometre stretch of this lava tube and getting to see the different formations along the way. It can be cold underground so be prepared. The ground is rough too so be confident in your footwear!

The cave itself is dark inside with few lights. The end is where the lava column is. It is so cold down there and there is no mobile reception. The path is not even (rocky floor) and it is a kilometre long! Anyway it is a nice experience.

Really interesting cave. Wear closed toe shoes as there is lots of moisture in there. Very affordable entrance fee. It’s a good place to take kids. It does get a bit dark in some places so I recommend taking a small flashlight.

A fantastic experience. Beautiful and surprisingly spacious. Also astonishingly empty -- at least when I went (late November). The ground inside is very uneven, so bring good shoes.
