Manjanggul Lava Tube
Jeju, South KoreaAbout Manjanggul Lava Tube
One of the world's finest lava tubes and part of Jeju's UNESCO World Natural Heritage site. About 1km is open to visitors, ending at a 7.6m lava column. It reopened on 30 May 2026 after a long closure, with new walkways; it's cool and damp inside year-round, so bring a layer. It's closed on the first Wednesday of each month.
