The Geomunoreum Volcanic Cone is one of the 368 parasitic cones distributed across Jeju Island. Located on the northeastern side of Jeju at a height of 400m, it is surrounded by numerous caves and is significant as the source of a group of 20 lava caves (including Gimnyeonggul Cave and Manjanggul Cave) in the area, formed when lava from this volcanic edifice flowed down the slope to the coast in the northeasterly direction. In this group of caves are cave systems running in three directions. The first cave system starts at Geomun Oreum and stretches for 13km, almost in a straight line, to Dangcheomuldonggul Cave, encompassing Baengdwigul Cave, Manjanggul Cave, and Gimnyeongsagul Cave. A study of the Natural Heritage District of Jejudo Island has found that the lava caves around Geomun Oreum in Seonheul-ri are of world standard in terms of scale, length, and cave organisms. In light of its value for research and as natural heritage, this site was nominated for UNESCO Natural Heritage listing.
