Are the Trang Islands better than the Krabi Islands?

For snorkelling quality and avoiding crowds, many visitors prefer the Trang Islands. Koh Rok offers coral comparable to the Similan Islands with a fraction of the visitor numbers. The trade-off is slightly less infrastructure and accommodation choices than Krabi or Phi Phi.

How do you get to the Emerald Cave?

The Emerald Cave is on Koh Muk, about 1 hour by speedboat from Pak Meng pier. You swim or snorkel approximately 80 metres through a dark cave at low tide to emerge in a hidden lagoon open to the sky. Tours typically operate morning only — arrive by 10 am before tidal conditions change.

When is the best time to visit Trang?

November to April is the dry season on the Andaman coast. May to October brings the southwest monsoon with rough seas and some closures of outer island tours. Trang town itself can be visited year-round.

About Trang Province

Trang is a relaxed and authentic province on Thailand's Andaman coast that remains significantly less visited than its neighbours Krabi and Phuket. The province has some of the most spectacular island scenery in the south — Koh Rok, Koh Muk with its Emerald Cave, Koh Ngai, and the Trang Islands archipelago offer world-class snorkelling and diving with far fewer tourists than equivalent sites in Krabi. The provincial capital is a pleasant market town famous for its dim sum culture and roast pork, a legacy of Chinese immigrant settlers. Trang's dugong population — the largest in Thailand — inhabits the seagrass beds around Koh Libong.
