Best Beach for a Selfie:
 Koh Kradan

While the islands of neighboring Krabi, such as Phi Phi and Lanta, have been increasingly inundated by tourists over the last decade, those to the immediate south have been slower to attract attention—though that’s likely to soon change. The reason why is that, put simply, Koh Kradan is the Thai island of your dreams. Located off the Trang coast, the slender island is mostly national park, with the few resorts lucky enough to call it home—including the most luxurious, the Sevenseas (doubles from US$400)—hugging the east coast. Here, a pristine white-sand beach borders azure waters home to tropical fish of all hues. At low tide, you’re able to walk a fair ways offshore, though not quite as far as sister islands Koh Mook—home to the famed Emerald Cave, an enclosed beach only accessible via a cave tunnel —and Koh Libong. Still, you’re here for one reason, so snap that selfie already.
