The Poso Wreck site lies close to Pulau Karang Congkak, where a sloping, patchy coral reef runs down to a flat sand bottom. The wreck sits on that sand at around 30 m, a short swim out from the foot of the reef.

Also known as Poso.

The dive

Divers usually enter by the lighthouse and follow the reef, which is easy to navigate, then take a short heading off it across the sand, at right angles to the reef, to reach the wreck at around 30 m. Yellowtail fusiliers, glassfish, snapper, barracuda, groupers and batfish hover in its shaded sections, while shrimps, nudibranchs and blennies live on the hull. Turtles pass by, stingrays bury themselves in the sand, and the shallower reef is busy with reef fish.
