About this audio guide
This guide to Geomun Oreum in Jeju traces what lies beneath the quiet forest around you: a network of lava tubes carved when this volcano erupted with runny basaltic lava roughly a hundred thousand years ago. It follows the flow as it raced some thirteen kilometers toward the coast, hollowing out tunnels including one you can walk through for kilometers underground. Access here is guide-led only, with numbers capped and the mountain closed one day a week.
