Jeju Island, a UNESCO World Natural Heritage site, offers breathtaking landscapes formed by volcanic activity over millions of years. Here are 5 unmissable natural attractions:
1. Hallasan Mountain (한라산)
South Korea’s highest peak (1,947m)
Hike through surreal ecosystems – from subtropical forests at the base to alpine flora at the summit. The Gwaneumsa Trail (8.7km) rewards hikers with crater lake Baengnokdam. Visit in spring for royal azaleas or winter for snowscapes.
2. Seongsan Ilchulbong (성산일출봉)
UNESCO-listed tuff cone rising from the sea
Climb the 600-step trail before dawn for legendary sunrises. The crater’s 90m-deep bowl resembles a giant crown. Nearby, Haenyeo (female divers) perform harvesting demonstrations. Best visited April-June.
3. Manjanggul Cave (만장굴)
World’s longest lava tube (7.4km)
Walk through 1km of accessible tunnels to see:
- 7.6m-high lava columns (world’s tallest)
- Lava stalagmites resembling turtle shells
- Striated walls showing volcanic history
Constant 11-21°C temperature makes this perfect year-round.
4. Cheonjiyeon Waterfall (천지연폭포)
“Pond of God” with 22m cascade
Follow the lantern-lit path through subtropical forest to witness:
- Rare Marae-do plants growing on cliffs
- Mulgogi (sweetfish) in crystal pools
- Illuminated night views after sunset
Tip: Combine with nearby Jeongbang Falls.
5. Oedolgae Rock (외돌개)
20m-high volcanic sea pillar
Walk the Sammaebong coastal trail for panoramic views where:
- Legend claims a general turned to stone waiting for his king
- K-drama Daejanggeum filmed pivotal scenes
Time your visit with high tide for the most dramatic waves.
