Busuanga Island is the largest island in the Calamian Group in the province of Palawan in the Philippines. Busuanga Island is, in fact, the second largest island in the province after Palawan island itself. The island is located halfway between the islands of Mindoro and Palawan with the South China Sea located to the west and the Sulu Sea to the southeast. South of the island are the two other major islands of the Calamian Group: Culion Island and Coron Island.
Busuanga Island is mainly known as a recreational diving location due to the twelve World War II Japanese wrecks that were sunk by American navy bombings in Coron Bay, a natural anchorage near the town center of Coron, on September 24, 1944.
