Emerald Cave (Tham Morakot)
ถ้ำมรกต
A sea cave on the west side of Koh Muk. After swimming about 80 meters through a pitch-black passage, you emerge into a secret beach enclosed by cliffs.
Emerald Cave lies on the west coast of Koh Muk, within Hat Chao Mai National Park. At low tide, follow a guide wearing a headlamp and a life jacket and swim through an 80-meter pitch-black sea-carved tunnel. The exit opens onto a small beach enclosed by vertical limestone walls, with light coming in from the top. Legend says it was once a pirate treasure hiding place. Island-hopping tours usually arrive between 9 and 11 a.m., and there may be a queue when it is busy. Arrive early or in the late afternoon for fewer people. The national park entrance fee is about 200 baht, collected by the boat operators. From May to October, during the monsoon season, the cave is often closed because of rough seas.
