Introduction to Haeundae Jangsan: According to geologists, Jangsan was formed due to a volcanic eruption about 62 million to 74 million years ago. This was once a basin inhabited by gigantic dinosaurs, but now it has become a popular recreational space for citizens. Only the volcanic rocks that can be seen everywhere tell the story of the past when the fire was shining. There are still Stone Age cultural relics unearthed in Changshan. It is said that there once was a small tribal country called Changshan Kingdom on the hillside of Changshan.
