Ilchulbong which looks like a grand old castle. It was formed 5,000 years ago by an underwater eruption on the shallow sea bed. Especially the exquisite inner structure which looks like a bowl formed with crater and slope, excluding the North West side and the repeated process of eating away and depositing by waves, all joined together make a surpassing sight. With a background of sun rising in the east beyond the horizon, the beauty of Seongsan Ilchulbong is beyond words description. That is why many people gather in this place on New Year morning to see the sun rise. The fatal attraction of the vast sea beneath a steep cliff and the white bubbles made by blue waves are so beautiful that it stir up one for a moment a desire to plunge into the sea. In addition, it is also recognized worldwide as a base for researches in past volcano eruptions and under water volcanoes.
