Cultural heritage
St. Paul Cave was known to local people since ancient times, in their thoughts it was inhabited by a spirit that prevented them from entering the cave. The park's territory and surroundings are the ancestral lands of the Batak people, of whom only 200-250 survive, and Tagbanua communities who live around the boundaries, including the coast. The Tagbaunas unlike the Bataks are generally acculturated to the Christian culture.
