Geological Wonders Hidden Underground

#hellohalloween
What sets Hallim Park apart is its remarkable geological features: the Hyeopjaegul and Ssangyonggul Caves. These are not just any caves; they are lava tubes formed by ancient volcanic activity, and walking through them is an incredible, humbling experience. The cool, damp air and the unique formations (including rare secondary formations that look like coral) provide a fascinating glimpse into the fiery history of Jeju Island. It’s an easy, well-lit walk that allows even the most casual visitor to witness a true natural wonder. This underground adventure adds an unforgettable, mysterious dimension to the park's surface-level beauty.
