It is surprising Stewart missed mentioning Kahumana Farms which is a large farm facility with a great vegetarian restaurant, trippy campus housing out of a fantasy movie, conference center, educational center, social services center, etc doing fantastic environmental and social things on many levels...
.
It may be that Kahumana Farms doesn't want to be seen as a touristy place and declines, for philosophical and ethical reasons, to be a "known" tourist stop - but it is one of the best stops anyone can ever make on the Waianae Coast to spend half a day and have a delicious veggie and fresh (locally caught) fish lunch.  
.
A high consciousness place, not a religious trip, just clear earth-concentric thinking and natural food.  A high without smoking anything.
