Seongsan Ilchulbong, also called Sunrise Peak, is a volcano on eastern Jeju Island, in Seongsan-ri, Seogwipo, Jeju Province, South Korea. It is 182 meters high and has a volcanic crater at the top. Considered one of South Korea's most beautiful tourist sites, it is famed for being the easternmost mountain on Jeju, and thus the best spot on the island to see the first sunrise of the year.
