3. Palawan, Philippines

Travel & Leisure magazine named Palawan the world’s “best island” three years in a row—and that’s definitely something. There aren’t enough words to describe this heavenly place. From unique beaches, emerald lakes, caves and mountains to abundant wildlife, Palawan is something that doctors should prescribe when you’re stressed.

Here you can explore the world’s longest navigable underground river (The Cabayugan River), see the the Philippines’ rarest birds, or enjoy a safari on Calauit Island. Of course, don’t forget to go wreck diving in Busuanga Island; you will spot WWI Japanese ships right off the coast.
