The Geomunoreum
Lava Tube
A lava tube, or pyroduct, is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave.

System is located between Seonheul-ri, Jocheon-eup and Weoljeong-ri, Gujwa-eup,
Jeju City,
Jeju-do. This lava tube system refers to a series of lava tubes formed while
basaltic lava flow which had erupted several times from the Geomunoreum volcano (which has an elevation of 456m) flowed in a north-northeast direction, down to the coastline for about 13km. It is estimated that it was formed between about 100 and 300 thousand years ago.
Lava tubes so far included in the Geomunoreum Lava Tube System are the Seonheul Vertical Cave, Bengdwigul Lava Tube, Bukoreumdonggul Lava Tube, Daerimdonggul Lava Tube,
Mangjanggul Lava Tube,
Gimnyeonggul Lava Tube, Yongcheondonggul Lava Tube, and Dangcheomuldonggul Lava Tube towards the sea. However, it is estimated that more tubes will be found. Bukoreumdonggul Lava Tube, Mangjanggul Lava Tube and Dangcheomuldonggul Lava are designated as natural monuments. Although these lava tubes are extremely large and ancient, the internal morphological features are well-preserved and the inner scenery is considered to be outstanding. As a result, "
Jeju Volcanic Island and Lava Tubes" are UNESCO World Natural Heritage Sites.
As study results about the Geomunoreum Lava Tube System are published in academic journals, this system is credited officially.
