Seongsan Ilchulbong in Korean, also called “Sunrise Peak”, is an archetypal tuff cone formed by hydro volcanic eruptions upon a shallow seabed about five thousand years ago. The 180m height fortress-like Seongsan Sunrise Peak tuff cone located in the eastern coast of Jeju Island, with its walls rising out of the ocean like old castle, shows a dramatic landscape feature and provides not only the finest example of various inner structure but also materials of being understand the process of eruption and accumulation of hydro volcano.

This area is the first to greet each day’s new sun, thus earning the name of “Sunrise Peak”. A hefty climb brings visitors to the top of the peak. Visitors are prevented from entering the crater by fence, but they can still enjoy the panoramic views of the surrounding area. Jagged rocks stick up like teeth along the crater’s perimeter. It is definitely worth the view even if you don’t make it in time for the sunrise.
