Keauhou Bay is a nice little dive when it gets too rough other places. Park in the Sheraton parking lot and walk to the right down the path to get to the bay. Dive from near the point of the Sheraton and back in to the boat ramp. Stay on the side of the bay and no problem. Boat traffic is usually further out, but watch/listen for them. Very clear dive and they fill air tanks at Fairwinds cruises at the end of the bay.
