Why dive here
With 182+ marine species recorded in the area - including barracuda, lionfish, mandarin fish, napoleon wrasse and nautiluses - Iro offers some of Rock Islands's richest wreck diving. Water ranges 29-30°C, warmest June, October, November.
The Iro is a Japanese WWII oiler, lying mostly intact between 16 and 131 feet. It’s a proper wreck dive, with plenty of penetration opportunities for those with the right training, but even from the deck, you’ll spot a surprising amount of detail. Keep an eye out for batfish and snapper shoals that often hang around the superstructure. It's a solid choice for advanced divers looking for a piece of history.
