Manisan & Chamseongdan Altar
마니산·참성단
The highest peak on Ganghwa Island. The stone altar Chamseongdan on its summit is traditionally said to be where Dangun, the legendary founder of Gojoseon, held rites to Heaven, and the National Sports Festival torch is lit here.
Mani Mountain rises to about 472 meters and is the highest peak on Ganghwa Island. The stone altar Chamseongdan on the summit is traditionally regarded as the place where Dangun, the legendary founder of Gojoseon, performed rites to Heaven. A Gaecheon Festival ceremony is held there every October 3, and the torch for the National Sports Festival is also lit at this site. The most common route is the stone stairway, with about 918 steps, taking roughly 1.5 hours one way. For better views, try the Dangun Ridge route, a rocky ridgeline overlooking the West Sea tidal flats and islands. The entrance fee is about 2,000 won. From Ganghwa Bus Terminal, take a bus for about 40 minutes to the Mani Mountain entrance.
