Kyo Maru Wreck - Subic Bay

The Kyo Maru is our pick for Subic’s most atmospheric wreck, a Japanese freighter torpedoed in 1944. Dropping to a flat 31 metres, it's a dive that instantly feels like stepping back in time. We love pushing into the cargo holds, where the light filters down through the superstructure, illuminating the ghostly outlines of machinery and scattered debris. Schools of batfish often hang motionless above the deck, almost part of the wreck itself, and we’ve often spotted lionfish tucked into shadowy corners. This isn’t a pristine, intact ship; rather, it’s a beautiful ruin, completely colonised by the sea. The forward mast, once reaching towards the surface, now lies across the deck, creating cool swim-throughs where we’ve found robust moray eels. Visibility can vary, especially after heavy rain, but on a good day, the scale of the Kyo Maru is genuinely impressive. It’s definitely an expert dive, requiring good buoyancy for penetration and a solid understanding of wreck protocols. For those who love exploring history underwater, this is essential Subic.
