Favorite thing: Puuhonua O Honaunau National Historical Park encompasses ancient temples, royal grounds, burial sites and a place of refuge (or puuhonua). It's worth spending some time exploring to check out the carved-wood representations of ancient gods; the stone board for playing konane, an ancient form of checkers played with black lava and white coral; and the wonderful snorkeling found off the natural lava steps just north of the place of refuge.
Favorite thing: take a drive around the island and see it's diversity. from the lava flowing volcano to a snow capped 13,000 foot mountain. from black sand beaches to the beautiful waterfalls set in the rainforests it is certainly a must see. there isn't the clutter of tourists here that oahu and maui seems to have.
Favorite thing: this is where you'd flee to if you've committed a crime in ancient hawaii. if you've managed to get to the designated area before being captured ''you cool''. google o.j. and ford bronco for an unsuccessful modern day attempt of this concept.
