Khao Sam Muk has symbolic significance in Chonburi.
Local people believe that the spirit of that mountain protects the fishermen from harm. One legend tells that the wife of a fisherman waited on the hill for her husband who was lost at sea.
Another legend tells that in the 18th century a poor Chinese girl named Sam Muk jumped to her death from the cliff after her parents objected to her marriage to her lover, becoming deified after her death.
In some versions both the girl and her lover threw themselves from the escarpment. Sam Muk hill appears in somewhat stylized form in the provincial seal of Chonburi.
