The Trang Islands sit off the Andaman coast of southern Thailand, in Trang province. Koh Muk is best known for the Emerald Cave, called Tham Morakot, which is reached through a passage that can only be passed at certain tide levels. Koh Kradan is a small island with quiet beaches and few resorts. Koh Libong, the largest of the group, has fishing villages and dugong habitat in its seagrass beds.
Trang town on the mainland is known for its old shophouses and for mu yang, Trang-style roast pork. Boats leave from Pak Meng pier. The islands suit beach days, snorkeling and boat trips, and make a calmer base than Phuket or Krabi. The drier months, roughly November to April, have calmer seas. From May to October, seas are rougher and boat trips are often cancelled. Plan at least three nights to visit one or two islands and the town.

Are the Trang Islands worth visiting?
Yes, for quieter beaches and snorkeling than the busiest Andaman islands. Boats often stop in the monsoon months, so the trip suits a few relaxed nights rather than a packed sightseeing schedule.
How do you get to the Trang Islands?
Fly to Trang Airport or take a bus to Trang town, then go by road to Pak Meng pier. Island boats leave from the pier, and the crossing time depends on which island you choose.
How many days do you need in the Trang Islands?
Two to four nights is enough for one island base, a boat trip and a cave visit if the tide allows. Add a second island only if the boat times make the move easy.
Which Trang island should I choose?
Koh Muk suits a first visit because of the Emerald Cave and frequent boats. Koh Kradan is quieter with few resorts, and Koh Ngai is good for snorkeling and beach days.
When is the best time to visit the Trang Islands?
December to March, when seas are calmer and rain is light. April is hot, and May to October brings rough seas and frequent boat cancellations.
Can I pay by card on the islands?
Often not. Many guesthouses and boat operators take cash only, so bring enough baht. Larger resorts are more likely to take cards.
