Jeju is a very beautiful island that brought tourists to Korea for their outstanding sights and landscapes. One of the most recommended places to go for discovering such beautiful places would be Seongsan mountain. Visitors climb up these stairs to the top of the inactive volcano mountain to see such a wonderful hill full of greens and nature. Some people said that that the mountain rose from under the sea in a volcanic eruption over 100,000 years ago. This would be one of the most recommended places to visit while staying in Jeju, Korea.
