Gimnyeong Cave, Manjanggul Cave
Gimnyeong Cave, Manjanggul Cave, Natural lava tube in Jeju Island, South Korea.
The Manjanggul cave system extends 7.4 kilometers underground with dark basalt walls, lava formations, and geological patterns throughout its length.
The volcanic tunnel formed between 300,000 and 200,000 years ago when basaltic lava flows from Geomunoreum created this underground network system.
South Korean authorities designated Manjanggul as Natural Monument 98 due to its scientific research value and contribution to understanding volcanic processes.
Visitors can explore one kilometer of the cave system on designated walkways, with cave temperature remaining at 11-16 degrees Celsius throughout the year.
The cave houses a 7.6-meter-high lava column, the largest known formation of its type in the world.
