Unofficially, Polihale has been incorrectly translated in many instances as the "House of the Po", where Po is the Hawaiian afterworld. By this account, spirits are said to travel to the coastal plain adjacent to the beach, and stay in the temple, known as the heiau. From there, they would climb the cliffs to the north, jump off into the sea to get to the mythical Po. The story further indicates that this belief was so strong that all the homes built in the vicinity of Polihale would have had no east facing doors, so that no traveling spirit could become trapped within.

The foregoing story, however, offers an erroneous translation of the place name. The name "Polihale" literally translates as "House Bosom".[1] The root Po refers to the original night/darkness from which creation is manifested. Po in this case is the "source"; poli, is literally "bosom" or "breast", revealing the word's root in the concept of "source of life". "Polihale" should not be literally translated as "bosom house", but "house bosom".

A sea lettuce called pahapaha grows in the waters near Polihale. A wreath made from pahapaha can fade and dry out, but when soaked in water, it will revive to its original freshness. Only the pahapaha from Polihale does this. According to mythology, Na-maka-o-Kaha'i, sister of Pele and Goddess of the Ocean, blessed Polihale's pahapaha with this special quality.
