Diving the Coron Wrecks from Skeleton Wreck Snorkel Depth to Irako Wreck at 43 Metres

Coron Wrecks Diving Skeleton to Irako

No single dive card covers every Coron wreck. The shallowest sits at two metres, the deepest at forty-three. The difference is the whole game. Your certification, plus the month you visit, decides which of these sunken WWII Japanese ships you can actually reach.

On 24 September 1944, US Navy aircraft from Task Force 38 sank a Japanese supply fleet sheltering in Coron Bay. A dozen wrecks lie scattered around Busuanga Island, each at a different depth. Coron town is the dive hub. The southwest monsoon runs July to mid-October, cancelling boats and churning up the visibility. Book for the dry months, November to May, when the water clears to thirty metres and dive operators run daily.

Skeleton Wreck Coron Snorkel Low Tide

The Skeleton Wreck is your entry point. No certification required. This 25-metre vessel, likely a small cargo ship or fishing boat, sits in just two to five metres of water. At the lowest tide its stern breaks the surface. Anyone who can swim can snorkel it.

Book a standard Coron Island lakes tour; most itineraries include a stop here. Your boat anchors nearby and you snorkel over the clearly visible outline. At low tide you get a sharp view of the coral-encrusted structure. This is one of only two wrecks genuinely open to non-divers.

The Lusong Gunboat Snorkel

The other is the Lusong Gunboat, a 35-metre patrol boat whose stern also rises to the surface at low tide. Its maximum depth is twelve metres, so the upper sections are easy to see from the surface. Most full-day island tours from Coron town stop at either the Skeleton Wreck or the Lusong Gunboat, rarely both. Confirm which one when you book.

Open Water Wrecks: Okikawa Maru to Akitsushima

An Open Water certification opens up the big fleet supply ships. These wrecks sit between ten and thirty-six metres. Their decks and superstructures fall within your eighteen-metre limit. Their keels lie deeper.

Start with the Okikawa Maru, a 168-metre oil tanker. Its shallowest point is at ten metres, the deck at sixteen to eighteen, the seabed at twenty-six. Operators run this as a first dive of the day. The Olympia Maru, a 122-metre cargo ship, is another solid pick: deck at eighteen metres, maximum depth at thirty.

The Akitsushima is a step up. This 118-metre seaplane tender starts at twenty-two metres and rests on a slope reaching thirty-six. Stay above eighteen metres and you miss most of it. Get an Advanced Open Water certification or book a guided deep dive with an instructor to see the wreck properly.

What to Expect on a Coron Wreck Dive

Coron Bay is a working environment, not a sanitised dive park. Expect strong thermoclines, sudden shifts from warm to cold water. Currents can be unpredictable. Most Coron town dive operators require you to have dived within the last year or to complete a checkout dive first. Ask for nitrox blends; they give you longer bottom times on these deeper profiles. You need the certification to use them.

Irako Wreck Coron Technical Dive 43m

The Irako is the deepest of the main wrecks and the reason technical divers come to Coron. This 147-metre refrigeration ship has its uppermost point at twenty-eight metres. Its keel rests at forty-three. The entire structure sits beyond the forty-metre recreational limit.

Penetration is possible inside the Irako, with swim-throughs into vast cargo holds and engine rooms. This is not a dive for the newly certified. You must hold at least an Advanced Open Water certification with a Deep specialty. Most reputable Coron operators will ask for proof of technical certification and penetration experience before they take you. The dive plan involves mandatory decompression stops. A nitrox blend or trimix is standard.

Book a two-dive day trip from Coron town. The Irako is the primary dive; follow it with a shallower wreck like the Kogyo Maru, a cargo ship sitting between twenty-two and thirty-four metres. That second dive works well for Advanced Open Water divers and lets you decompress after the deep profile.

Coron Bay WWII Japanese Wrecks

The fleet was caught at anchor, believing itself hidden among the islands, when US fighters found it. The sinking was swift and the ships landed remarkably intact on the seabed. You see that history in the details: the Akitsushima still has its massive crane for lifting seaplanes, and the Irako's refrigeration machinery remains in place.

That history shapes your dive. The ships were loaded with supplies. You will see truck tyres on the Okikawa Maru and sake bottles inside the Irako. The wrecks are now artificial reefs, encrusted with soft corals, holding schools of batfish, barracuda, and resident lionfish.

To grasp the scale, book a multi-wreck package with a Coron town operator. A two-tank trip visits two different wrecks, giving you a cross-section of the destruction. Dedicate three to four diving days in Coron. Work your way from the shallow snorkel sites up to the deeper technical challenges.

Coron Wreck Dive Operator Busuanga

Your dive hinges on the operator you choose. Coron town, on Busuanga Island, had between thirty-five and forty-five dive shops as of 2024. They range from backpacker day boats to technical specialists running full mixed-gas support.

Book directly in town. Arrive, wait a day or two, assess the weather and sea conditions, then commit. Do not pre-book online from abroad for a specific date. The southwest monsoon from July to mid-October frequently grounds all boats. Reputable operators will be transparent about their safety records, guide credentials, and gas mixes. They should brief you on each wreck's profile, current potential, and penetration rules before you board.

Budget for extras. The dive trip price rarely includes the environmental fee, paid in cash at the port. That fee covers reef conservation and is collected by the local tourism office; the amount changes, so ask your operator for the current figure. Also carry cash for gear rental. Most island ATMs run dry by Sunday afternoon.

Who Should Dive the Coron Wrecks

This is for competent, current divers comfortable with variable conditions and deep profiles. It suits adventure-minded couples and small groups chasing raw history over luxury.

Who Should Skip It

Skip the Coron wrecks if you are a new Open Water diver with fewer than twenty logged dives, or if you demand perfect visibility every day. The logistics and depth demands make it a poor choice for families with young children or anyone on a tight five-day Philippines itinerary. If you cannot dedicate a full week to Palawan, pick Coron or El Nido, not both. The ferry between them eats an entire day.
