Seongsan Ilchulbong was formed by an eruption under the sea. At the top is a huge bowl-shaped crater about 600 m across, and it is part of the Jeju Volcanic Island and Lava Tubes UNESCO World Natural Heritage Site.
When to go
As the name (“Sunrise Peak”) suggests, it is famous for sunrise. In spring the fields around it turn yellow with canola flowers — a postcard view. On the way up, turn around for views over Seongsan village and the sea.
Make it a Jeju trip
Jeju is a volcanic island with a mild climate and a culture of its own, about an hour’s flight from Gimpo Airport. With Hallasan, crater hills and the Jeju Olle walking trails that circle the island, it is best with two days or more. Renting a car (with an international driving permit) is the easiest way to get around.
