Papua Drop-Off: easy south-coast reef with a cavern
Papua Drop-Off is an easy south-coast boat dive built around a sand channel, a shallow reef plateau and a small cavern opening. Divers can keep it relaxed on the plateau or follow the drop-off more gradually, which makes the site a good fit for beginners, freedivers and anyone who wants a flexible reef day. Eagle rays, turtles and giant clams are the standout sightings.
