Ral Island - Rabaul & New Britain

Ral Island is a good choice for a third dive, especially after something like Deep Pete, or if you're just after an easier afternoon. The coral garden surrounding the island stays shallow, mostly between 5 and 15 metres, which keeps things relaxed and light. We often find ourselves cruising over healthy corals, but the real fun here is poking around the sandy slopes. Keep your eyes peeled for decorator crabs, maybe a seahorse or pipefish tucked into the seagrass, and plenty of nudibranchs. We’ve even spotted a mimic octopus here once, so it pays to take your time and look closely.
