Manjanggul Lava Tube [National Geopark]

만장굴 (제주도 국가지질공원) · Jeju · Parks & nature

Manjanggul Lava Tube, located in Gimnyeong-ri, Jeju, is part of the Geomunoreum Lava Tube system. The lava tube stretches roughly 7,400 meters, with a maximum height of 25 meters and width of 18 meters. These measurements make it one of the largest lava tubes in the world. Manjanggul holds great value for science and conservation studies, having well-maintained formations despite being formed over one hundred thousand years ago. The majority of the cave is closed off, with only 1 kilometer being open to tourists. Within this open section, visitors can see a variety of lava tube and cave topographical features, including stalagtites, stalagmites, and stone pillars. Among these, the 7.6-meter-tall stone pillar at the end of the open section is recorded as the largest in the world.
