About Geomunoreum Lava Tube System

 

The Geomunoreum Lava Tube System, located on Jeju Island in South Korea, is a stunning testimony to volcanic activity. This World Heritage Site comprises one of the finest lava tube systems in the world, featuring five major caves: Bengdwigul, Manjanggul, Gimnyeonggul, Yongcheondonggul, and Dangcheomuldonggul. These tubes are the result of lava flows from the Geomunoreum volcano, which erupted approximately between 100,000 to 300,000 years ago. Manjanggul, the most accessible and longest, extends over 13 kilometers and offers visitors a glimpse into the past with its well-preserved stalactites, lava stalagmites, and flowlines. The cave system's ecosystem supports a variety of species, including bats and endemic cave-dwelling organisms. Key recreational opportunities include guided tours of the more accessible sections of the caves, particularly Manjanggul, recognized for its striking lava formations and extraordinary size. The allure of the Geomunoreum Lava Tube System is enhanced by Jeju Island's larger volcanic landscape, offering adventurers a chance to explore seamless natural beauty.
