O.K. UNO - Subic Bay

The O.K. UNO isn’t your typical deep-water wreck. This former fishing vessel ran aground during Typhoon Ruby in 1988, leaving her bow high and dry on the beach at Grande Island, while her stern slopes into the shallows. It's a unique dive, accessible to almost everyone because the deepest parts are only around 8 metres. We love the way the wreck has become part of the shoreline. You can walk right up to the bow, then kit up and swim along the hull as it descends. Inside, the wheelhouse is still largely intact, an eerie skeleton draped in fishing nets, and there are some cool swim-throughs into the engine room. Our favourite part is the stern, which has become a haven for juvenile fish. Look closely and you'll spot clouds of glassfish, cardinalfish, and tiny damselfish darting between the rusted plates. It's a fantastic spot for macro photographers and those looking for a relaxed, easy dive with a bit of history. Try it in the late afternoon; the light plays beautifully through the superstructure.
