Seongsan Ilchulbong, also known as 'Sunrise Peak', is a distinctive tuff cone formed by hydrovolcanic eruptions over 5,000 years ago. Located on the eastern coast of Jeju Island in South Korea, this UNESCO World Heritage Site is renowned for its well-preserved crater, approximately 600 meters in diameter and 90 meters high. Visitors can hike up the well-maintained trail to the summit to witness the panoramic views of the ocean, nearby islands, and the lush landscape of Jeju. Seongsan Ilchulbong is particularly famous for its spectacular sunrises, which is why many tourists make the effort to climb it early in the morning. The site also hosts an annual festival celebrating the natural scenery. Its grassy crater, coastline, and the diverse species found here contribute to its scientific and educational value. Beyond its geological significance, the peak is also culturally important to the islanders, and it features in many local legends and tales. It is one of Jeju Island's top attractions, offering insight into the area's natural history while providing a challenging and rewarding outdoor experience for visitors.
