Overview
At 469 m, Manisan is the highest peak on Ganghwa Island and one of Korea's most legendary mountains. The summit hosts Chamseongdan, a stone altar said to have been built by the mythical founder-king Dangun over 4,000 years ago.
Highlights
- Chamseongdan altar: An ancient stone platform where the National Foundation Day fire is still kindled each October 3.
- Ridge trail: The main hiking route (3.5 km, ~2 h up) passes through mixed deciduous forest with wildflowers in spring.
- Summit panorama: On clear days the views span the Yellow Sea, the Han River estuary, and the faint outline of North Korea.
History
Legend attributes the mountain's altar to Dangun, the mythological progenitor of the Korean people (c. 2333 BCE). Whether or not the altar is truly ancient, the mountain has been an important ritual site since at least the Goryeo Dynasty.
