13/10/08; Jeju-do (Island); 63 ha; 33°24'N 126°36'E. Within National Park and UNESCO World Heritage site and Biosphere Reserve. A volcanic crater lake at above 900m altitude on Jeju Island, with a forest of broad-leaved deciduous trees. On the water-scarce island, the crater lakes on such parasitic cones around Mt Hallasan provide an important store of rain water, and this site retains some water even through the dry season. A number of endangered fauna and flora species are present, including Peregrine falcon, Fairy pitta, Black kites, and Black paradise flycatchers, as well as Japanese forest peony (paeonia obovata). It is considered to be one of three holy mountains on the island and is associated with legends of the giant goddess Seolmundae. Only limited human access is permitted to the area. Ramsar site no. 1847. Most recent RIS information: 2009.
