Easy Nouméa wreck-reef with open ribs and passing fish.
La Diéppoise is an easy Nouméa wreck-reef with open ribs, a clean interior view, and schools of fish gathering around the structure. Originally built with a wooden hull to reduce magnetic mine risk, it now reads as an artificial reef where sharks and rays may occasionally pass by. Plan it as a careful boat dive rather than a quick look, and spend time tracing the ribs, frame, and fish life around the wreck.
