Seongsan Ilchulbong, Volcanic tuff cone in Jeju Island, South Korea.
Seongsan Ilchulbong is a volcanic tuff cone rising on Jeju Island, towering roughly 182 meters above sea level. The summit features a wide crater with steep inner walls, while the rim is defined by a distinctive jagged rock formation that frames the eastern coastline.
This volcanic cone formed approximately 6,700 years ago through hydrovolcanic eruption on the shallow seabed near Jeju Island. The eruption created a robust structure composed of volcanic ash and rock fragments, which has endured and shaped the eastern landscape.
Local communities have long gathered here to celebrate the new year's first sunrise, making it a focal point for seasonal traditions and communal gatherings. The place hosts performances and celebrations that draw families and visitors seeking to participate in these longstanding customs.
A wooden staircase leads to the summit, with the climb taking roughly 30 minutes and being fairly straightforward for most visitors. The path is well-maintained with viewing points along the way, so staying on the marked route keeps you oriented and safe.
The crater's rim is formed by roughly 99 individual rock spikes that together create a crown-like silhouette. This natural arrangement developed through the way volcanic material was deposited and weathered during and after the eruption.
