Jeju Island is a volcanic island located off the coast of the Korean Peninsula that has received UNESCO World Heritage Status for its outstanding natural assets, which include the finest lava tube system on the planet.
In addition to the remarkable Manjanggul Lava Tube Cave, which has multi-colored carbonate roofs, floors, and lava walls, the island is home to Mount Hallasan, the tallest mountain in Korea, which boasts waterfalls, forests, and a lake-filled crater.
You can learn all about the remarkable geology of Jeju Island on a guided day tour from Seoul, or spend a little longer on the island and visit Mount Halla National Park, where you can hike along a very scenic 9-mile shaded forest trail.
