Manjanggul Cave Tourism

Manjanggul Cave is one of the finest lava tunnels in the world and is a UNESCO World Natural Heritage site located in Jeju Island, South Korea. Extending for about 7.4 kilometers, it was formed about 200,000-300,000 years ago as part of the Geomunoreum lava plateau. Out of its lengthy formation, only about 1km is open to the public. This cave is renowned for its fascinating geological structures, including the lava stalactites and stalagmites, and the lava columns and flowstones. Perhaps the most noteworthy feature of the cave is the 'Stone Turtle,' which is shaped like Jeju Island and is thought to be a guardian of the island's Hallasan Mountain. The cave's environment maintains a consistent temperature of about 11-21°C throughout the year, offering visitors a cool respite from Jeju's external climate. The internal lighting provides a dramatic view of the cave's features, but visitors are encouraged to bring flashlights to better observe the details of the lava formations.
