Pu’u Keka’a, great place to swim with the Honu. The hotel has this cliff diving ceremony nightly along with a story.
The story goes that every island has this "jumping off" point, a place where one would go at death to join ancestors, if they cannot be shown the way by the family guardian animal spirit or ‘aumakua, they would wonder this area eventually attaching to nearby rocks. Perhaps this is why it is considered very bad luck to remove and take rocks?
