Overview
Formed over 450 million years, this Natural Monument earns its 'underground palace' nickname with dense stalactites, stalagmites and columns along a 1.7km route of narrow passages and steep steel stairs — an explorer's cave, never a dull walk. A constant 15°C makes it summer refuge and winter shelter alike, five minutes from downtown, with Gugyeong Market's garlic snacks waiting after.
Travel Tips
Wear the helmet — ceilings drop low — and grippy shoes. Peak-season weekends favor morning visits.
