Manjanggul formed when the surface of a lava river cooled while the lava inside kept flowing out.
Checked · Researched, not yet visited · times from official timetables and our estimates · Takumi Yamada
A lava tube over seven kilometres long, one of the longest in the world, with a walkable section lit and decked. Reopened on 30 May 2026 after almost two and a half years closed for safety repairs; closed the first Wednesday of the month.
- Number 3 of ten on our list for Jeju.
- Closed the first Wednesday of the month. Check the day before you plan around it.
- 2 hr 50 min door to door needs a 5-hour call: a 2–3 hour stop cannot hold it. Pick something closer instead.
- No single published ride covers this one. Budget for a taxi both ways, or fold it into a guided day.
Manjanggul lava tube and your ship
Both pins on one map, so the distance is a fact rather than a feeling.
Where the 2 hr 50 min goes
The hour before all-aboard is not in this bar; it is already set aside. The minutes are our estimates from timetables and maps, not timed on the ground.
If your ship is late, cut the 1 hr 30 min in the middle. Never cut the hour at the end.
Routes that already include it
Finished days timed from official timetables and our estimates, with this stop in them.
East Jeju: the crater and the lava tube (Jeju Port)Needs an 8-hour call · ~6h door to doorLong calls at the northern terminal
The rainy-day Jeju (Jeju Port)A wet day · ~4.5h door to doorWet weather at the northern terminal — underground and under roofsWhat to put beside it
Each of these still lands you back aboard with the hour to spare.
