Park along Beach Road, or along Diamond Head Road if Beach Road is full (buses will have to drop students off at the top of Beach Road). Beach road ends just under the Diamond Head lighthouse. It looks like a driveway (and is sometimes missing the sign). Walk south along the shore, past a small cove, until you come to a flat bench with grooves. This is the OPIHI site.
