Beginning in 2013, Palawan, Philippines, has been voted as the best island in the world by readers of Travel+Leisure a number of times in its yearly polls and in the top 3 rankings by Condé Nast Traveler. With huge limestone cliffs rising from palm-fringed white sand beaches, gorgeous seascapes, old-growth rainforests, subterranean rivers and impressive aquatic and terrestrial biodiversity, the island has been dubbed as the country’s “Last Ecological Frontier.”
