The walk is 11.5 km, takes about 4 to 5 hours, and has a low difficulty level. This is the very first Olle path. It connects an oreum (volcanic cone) with the sea, and so it is called “Oreum-Badang Olle.” It starts at the small, pretty Siheung Elementary School, passes grassland which is green in all seasons, and goes to Meolmi Oreum and Al Oreum. You can see Seongsan Ilchulbong Mountain and Udo Island, as well as the sea, which is like a mosaic. While walking, you can also enjoy the great view of the grass surrounding the black stone walls, which you can only see on Jeju Island.
