Trang is a beautiful southern province on the Andaman coast. First known for its annual underwater wedding festivities, it really has much more to offer. One of the more amazing sites is Tham Morakot, or the Emerald Cave on Koh Mook. You need to hire a boat at Pakmeng or Chaomai, about an hour out of town. Then, it’s another hour or so by boat. But don’t let the boat take you in, better to swim or paddle a kayak through the dark cave entrance, which then opens to an emerald lagoon and white sand beach protected by limestone cliffs that reach like fingers for the blue sky above.
