Seongsan Ilchulbong, also known as Sunrise Peak, is a stunning volcanic tuff cone located on the eastern coast of Jeju Island, South Korea. Formed over 5,000 years ago by a hydrovolcanic eruption beneath the sea, this UNESCO World Heritage Site is renowned for its unique bowl-shaped crater and dramatic cliffs rising steeply from the sea. The cone reaches a height of 182 meters and is surrounded by lush green slopes and panoramic coastal views, making it one of the island’s most iconic natural attractions. A popular spot for early risers, Seongsan Ilchulbong is famous for its breathtaking sunrise views, drawing thousands of visitors who hike to the summit each morning to witness the sun emerge over the horizon. The trail to the top is well-maintained and takes around 20 to 30 minutes, rewarding hikers with spectacular vistas of Jeju’s landscape and the turquoise sea. In addition to its geological significance, the area is rich in biodiversity, including rare plant species and Haenyeo (female divers) performances near the base. Easily accessible by bus or car, Seongsan Ilchulbong Tuff Cone is a must-visit destination for nature lovers, hikers, photographers, and anyone exploring the natural wonders of Jeju Island.
