Dive-site story
The Olympia Maru is an intact Imperial Japanese Army freighter sunk during the US air raid on Coron Bay in September 1944. Sitting upright on the sandy seabed, the wreck provides wide cargo holds that offer straightforward penetration routes under natural ambient light. Large schools of batfish congregate around the superstructure while soft corals encrust the masts and deck winches.
