For a glimpse of ancient Hawaii, you'll want to head for Pua Loa Petroglyphs, found near the 15-mile marker on the Chain of Craters Road. Here, a quick half-mile walk takes you to a circular boardwalk for viewing thousands of Hawaiian petroglyphs carved in stone.

This sacred place has an unusual history: Fathers in ancient Hawaii came here to bury their newborn's umbilical cord in the tiny holes in the lava. This ensured a long life for the child.

Please don't do any petroglyph rubbings, as this will destroy them over time. A photo is much better. Also, you're requested to stay on the boardwalk.
