Coron is one of the great wreck-diving destinations of Asia. The ships — auxiliary supply vessels, tankers, freighters, a seaplane tender — lie scattered across the bay between Coron and Busuanga, most of them in 10 to 40 metres of water and accessible to recreational divers. Visibility is variable but the marine life is extraordinary: schools of batfish, lionfish, scorpionfish, nudibranchs everywhere, and reef life now covering virtually every steel surface.
The most popular wrecks are the Akitsushima (a seaplane tender, deeper at around 38 m), the Olympia Maru (a freighter, well-suited to penetration), the Irako (a refrigeration ship, the deepest of the main sites), and the shallow Lusong gunboat, parts of which lie at only a few metres and can be snorkelled. Most dive operators in Coron town run daily two- and three-tank trips to the wrecks; advanced or wreck certifications are recommended for the deeper sites.
