Getting There & Around

How to Get to Mu Ko Chang National Park

Mu Ko Chang National Park (Ko Chang) is on Ko Chang island in Trat province. Most visitors reach the island via Trat: take a bus or drive from Bangkok to Trat (roughly 300 km by road), then continue to the Laem Ngop/Laem Ngob ferry piers on the mainland. Regular car and passenger ferries run from Laem Ngop (Ao Thammachat/Centrepoint piers) to Ko Chang (White Sand/Bang Bao areas); the ferry crossing typically takes about 30-45 minutes. Once on Ko Chang, use local songthaews, motorbike taxis or taxis to reach park beaches, trailheads and ranger stations.

Tips for Visiting Mu Ko Chang National Park

  • Plan your visit in the dry season (roughly November-April) when seas are calmer and interior trails are easier to access, avoiding the monsoon months when many park services are reduced.
  • Most visitors arrive at Koh Chang by ferry from Trat (Laem Ngop pier); factor in the boat timetable when planning day trips and check with local operators for which piers they use that day.
  • To escape the busiest beaches around White Sand and Bang Bao, explore quieter northern or southern bays or hire a local longtail to reach smaller islands and snorkel sites inside the national park.
