    Site Overview

    Helmet Wreck (Depth Charge / Buoy 6 Wreck), within the Koror Area – Wrecks & Macro of Palau, is one of the region's most rewarding dive sites and a highlight of any Micronesian diving trip. A 30 m Japanese patrol boat still strewn with soldiers' helmets and ammunition, now a colourful artificial reef. Geographically the site features wreck and hull formations built from steel and coral substrate, dropping from a shallow top of around 18 metres to a maximum depth of about 30 metres, with an average working depth near 22 metres. Visibility is typically excellent, ranging from 12 to 28 metres, while water temperatures hold between 27 and 30 degrees Celsius year-round. The marine life is the headline attraction. Divers routinely encounter Lionfish (Pterois volitans), Batfish (Platax orbicularis), Glassfish (Parapriacanthus ransonneti), Moray Eel (Gymnothorax javanicus), Nudibranch (Chromodoris), alongside dense reef fish, invertebrates, and the soft and hard corals that blanket the reef. The mix of nutrient-rich currents and Palau's protected status makes Helmet Wreck (Depth Charge / Buoy 6 Wreck) one of the most reliable places in the country to see both abundant macro life and large pelagic visitors on a single dive. Helmet Wreck (Depth Charge / Buoy 6 Wreck) is best enjoyed as part of a boat programme out of Koror, and it rewards wide-angle photographers, naturalists, and adrenaline-seeking drift divers alike. The Palau Protected Areas Network helps keep the reef pristine, so divers are asked to maintain perfect buoyancy and respect the fragile coral at all times.

    Dive Briefing

    "Your dive at Helmet Wreck (Depth Charge / Buoy 6 Wreck) begins with a controlled descent along the mooring line or wall, depending on the current on the day. You swim the deck and peer into the holds where the helmets remain, surrounded by soft corals and schooling fish. Plan to spend the deepest portion of the dive along the wreck between 18 and 22 metres, where the steel is most colourful and the larger fish congregate. No hooking needed; deploy your DSMB and keep clear of the fragile cargo when ascending. Mid-water, watch the blue beyond the wall for passing Lionfish (Pterois volitans) and other pelagics, and keep an eye on your no-decompression limits given the depths involved. Ascend slowly with a safety stop at five metres to off-gas safely. Because Helmet Wreck (Depth Charge / Buoy 6 Wreck) can experience mild currents and occasionally reduced visibility after heavy rain, dive with a surface marker buoy and always follow your operator's site-specific briefing and emergency plan."

    Traveler Notes

    Who is this for?

    Helmet Wreck (Depth Charge / Buoy 6 Wreck) is aimed at intermediate divers holding at least a Open Water certification, and it suits those comfortable managing mild currents and maintaining neutral buoyancy along vertical terrain. Photographers, marine-life enthusiasts, and experienced drift divers will find it especially rewarding, while history buffs and photographers will enjoy the eerie cargo, while beginners can stay on the shallow deck. Divers who prefer calm, shallow, zero-current conditions should choose one of Palau's sheltered lagoons or house reefs instead, and anyone without the recommended certification should complete a check-out dive with a local operator first.
