Palawan. An island surrounded by the South China Sea and Sulu Sea, the Province of Palawan is the largest yet least populated in the country. Its beauty lies beyond the untouched natural formations of limestone, cliffs, caves, lagoons, undiscovered forest, mountains and so much more. Visit UNESCO world heritage sites - Tubbataha Reef Marine Park and Puerto-Princesa Subterranean River National Park and be marveled by what nature has to offer. Coron Island, situated in Northern Palawan, is another gem worth discovering.
