Seongsan Ilchulbong Peak [UNESCO World Heritage] (Trekking : 60 minutes) Seongsan Ilchulbong Peak rose from under the sea in a volcanic eruption over 100,000 years ago. Located on the eastern end of Jejudo Island, there is a huge crater at the top of Seongsan Ilchulbong Peak. The crater is about 600m in diameter and 90m high. With the 99 sharp rocks surrounding the crater, it looks like a gigantic crown. While the southeast and north sides are cliffs, the northwest side is a verdant grassy hill that is connected to the Seongsan Village. The ridge provides an ideal spot for walks and for horse riding as well.
