Mt. Chiryeonsan on Saryangdo Island

in Saryang-myeon, Tongyeong, is a chain made up of seven mountains that run in a north-south direction, which is how it earned its name. On Mt. Mangsan (Gongsusan), one of the seven mountains, is an old beacon tower that was used to signal national emergency in the olden days.
The unobstructed view in all directions as well as the many guideposts and mountaineering information signs along the ridgeline and trails linking the seven mountain chains make mountaineering pleasant and easy.
