Jeju Island is home to some natural World Heritage Sites, including: Jeju Volcanic Island and Lava Tubes. This island was formed through volcanic activities a long time ago, which created countless parasitic cones- called ‘Oreum’ (in the Jeju language). This can be understood as a hill or a mountain. It is a great joy to hike Oreum. You should experience the amazing scenery of Oreum for yourself. If you follow a hiking course, which we will next introduce, you will visit the Oreum Volcanic Cone named Gogeunsan Mountain. In addition, you can also explore nearby tourist attractions, while enjoying a variety of different restaurants.
