Why go

Manjanggul Lava Tube is one of the world's longest lava tubes — a 7.4-km volcanic cave on Jeju formed by lava flows over 200,000 years ago. The cave is registered as UNESCO World Natural Heritage and as part of Korea's National Geopark. About 1 km of the cave is publicly accessible, with massive lava columns, lava stalagmites, and the world's largest known 'lava column' (7.6 m tall). For travelers seriously interested in Korean geological heritage, Manjanggul is the strongest single pick on Jeju and one of the most consequential geological destinations in the country.
