Getting There & Around

How to Get to Hat Chao Mai National Park

From Trang town, drive south on Route 4 or take local buses toward Sikao/Pak Meng; boats to offshore sites depart from Pak Meng or nearby piers. The park is reachable by car or organized tours from Trang.

Tips for Visiting Hat Chao Mai National Park

  • Take a long-tail boat from Trang's Pak Meng or Khanom piers to reach the park's marine or beach areas.
  • Visit the park's underwater attractions via guided snorkeling tours rather than alone-local guides know seasonal currents.
  • Avoid the midday sun on beaches - the southern Gulf of Thailand can be intense; late afternoon light is best for photography.
