Scuba Diving in Coron

Diving in Coron

Diving in Coron is a bucket-list stop for anyone who loves wrecks. In September 1944, a US airstrike sank a Japanese supply fleet in the sheltered bays around Busuanga, and eight decades later those ships have become some of the best wreck dives on Earth. They rest in calm, protected water, wrapped in soft and hard coral and patrolled by batfish, groupers, and lionfish, with everything from shallow decks a beginner can explore to deep engine rooms only advanced divers should penetrate.

What makes Coron special is the range within a single destination. The Okikawa Maru sits shallow enough for wreck newcomers, while the Irako and Akitsushima drop into technical territory with dark cargo holds and passageways. Then there's Barracuda Lake, a surreal freshwater dive where the temperature spikes as you descend. The wrecks lie a short boat ride from Coron town, visibility runs 5 to 20 m (16 to 66 ft) depending on the site and day, and the dry season from November to May brings the calmest conditions. This isn't a big-pelagic destination, it's about history, structure, and the strange thrill of finning through a sunken ship.

Okikawa Maru

Okikawa Maru is widely considered the best all-around wreck in Coron, and the friendliest for divers new to wrecks. This oil tanker rests upright with its deck between 10 and 16 m (33 and 52 ft) and the bottom around 26 m (85 ft), so you can enjoy the highlights without going deep. The hull is completely covered in coral, and schools of fish drift through the structure, with plenty of easy swim-throughs for those with the right training.

• Depth: 10–26 m (33–85 ft)
• Visibility: 10–20 m (33–66 ft)
• Current: Gentle to Moderate
• Level: All Levels to Intermediate
• Key species: Batfish, groupers, lionfish, scorpionfish, reef fish

Irako

Irako is the wreck the technical divers come for, a Japanese refrigeration ship sitting upright and remarkably intact. The deck lies at 28 to 35 m (92 to 115 ft) and the bottom reaches 43 m (141 ft), with a maze of passageways and cargo holds that many consider the best penetration in Coron. This is a deep, serious dive that calls for Advanced Open Water plus deep or wreck training, and often a decompression plan.

• Depth: 28–43 m (92–141 ft)
• Visibility: 10–20 m (33–66 ft)
• Current: Moderate
• Level: Advanced to Technical
• Key species: Groupers, snappers, batfish, lionfish, glassfish

Akitsushima

Akitsushima is Coron's only warship, a seaplane tender lying on her port side. Her upper hull rises to about 22 m (72 ft) and the bottom sits around 36 m (119 ft), with strong current possible and visibility averaging 15 m (49 ft). Experienced wreck divers can follow penetration routes deep into the ship, including a run up the propeller shaft into the engine room, making this one of the most rewarding advanced dives in the bay.

• Depth: 22–36 m (72–119 ft)
• Visibility: 10–20 m (33–66 ft)
• Current: Moderate to Strong
• Level: Advanced
• Key species: Groupers, batfish, scorpionfish, snappers, reef fish

Barracuda Lake

Barracuda Lake is unlike anything else in Coron, or almost anywhere. You climb over a limestone ridge to reach a hidden lake, then descend through a sharp thermocline, the layer where water temperature changes fast, and the water jumps from around 28 °C (82 °F) to over 38 °C (100 °F). The dramatic karst walls, warm bathwater feel, and mirror-like haloclines where fresh and salt water meet make it a surreal, otherworldly dive that photographers love.

• Depth: 4–35 m (13–115 ft)
• Visibility: 5–15 m (16–49 ft)
• Current: None
• Level: All Levels to Intermediate
• Key species: Barracuda (occasional), shrimp, few fish; the draw is the geology, not the marine life

Best time to dive Coron

The best time to dive Coron is the dry season from November to May, when the bays are calm and the wrecks are at their clearest.

Because the wrecks lie in protected bays, Coron dives well most of the year, but November to May gives you the driest weather and calmest crossings. Visibility on the wrecks depends more on tide and plankton than season, so a good operator will time dives for the clearest water.

Marine life in Coron

Marine life in Coron grows on and around the wrecks. Decades underwater have turned these ships into artificial reefs, their hulls thick with soft and hard coral and home to the resident fish that shelter in the structure. It's not a destination for big pelagics, it's a place where the marine life and the history are wrapped together.

• Wreck dwellers: Batfish, groupers, lionfish, scorpionfish, and clouds of glassfish
• Reef life: Sea turtles, snappers, sweetlips, nudibranchs, and reef fish on the surrounding coral
• Coral growth: Soft corals, sponges, and hard coral encrusting the hulls

Wreck macro (nudibranchs, scorpionfish, frogfish): year-round on the coral-covered hulls.

Sea turtles: year-round around the shallow reefs and the tops of the wrecks.

The Calamianes reefs and wrecks around Coron are increasingly protected, and dive operators emphasize careful wreck etiquette, keeping fins clear of the fragile coral growth and disturbed silt inside the ships. Responsible penetration and good buoyancy protect both the divers and the wrecks that took decades to become reefs.

Getting there

Fly into Francisco B. Reyes Airport on Busuanga, a 45-minute to one-hour hop from Manila or a connection from Cebu, then transfer about 30 to 45 minutes to Coron town. Ferries also run from Manila for those with more time and a smaller budget. From Coron town, dive centers run daily boat trips out to the wrecks, most of which are a short ride across the bay.
