Wonhyoam is a branch hermitage of Naewonsa in the middle of Cheonseongsan in Yangsan, at an elevation of 700 meters. Wonhyo Daesa founded it, and the view looking down over downtown Yangsan is its defining feature. The Daeungjeon is a new building, other new structures stand around it, and natural spring water is available to drink. Reaching it requires climbing to just below the summit of Cheonseongsan, so getting there is not easy.
