Puuhonua o Honaunau National Historical Park, considered one of Hawaii's most sacred sites, is a 40-minute drive south from Kailua Kona. The site was formerly royal grounds and a "place of refuge" for ancient lawbreakers. Take a self-guided walking tour amidst the restored, centuries-old temple and fishponds alongside the ocean and soak up the history.
Visit the 223-acre Puako Petroglyph Archaeological Preserve and see more than 3,000 ancient kii pohaku, Hawaiian petroglyphs. Some of these images carved into lava rock date back to 1200 AD. It's thought the carvings of people, canoes, turtles and various symbols represent births and other important events.
