The long-tail engine clicks to life and the sea answers, pushing the boat out of Old Town Pier as limestone cliffs shrink into the rearview. Sun hits the Andaman like a sheet of glass; the guide trims the motor and the boat drifts toward a string of small islands whose names are spoken like directions to a secret — Koh Chuak, Ko Muk, Koh Ngai, Ko Maa.

The long-tail engine clicks to life and the sea answers, pushing the boat out of Old Town Pier as limestone cliffs shrink into the rearview. Sun hits the Andaman like a sheet of glass; the guide trims the motor and the boat drifts toward a string of small islands whose names are spoken like directions to a secret — Koh Chuak, Ko Muk, Koh Ngai, Ko Maa.
These islands sit on the southern edge of the Andaman shelf, where karst towers rise from shallow coral platforms. The geology is Pleistocene limestone carved into caves and narrow passages; the most famous is Emerald Cave on Ko Muk, a short, dark swim through a tunnel that opens onto a sunlit beach. Koh Lanta’s Old Town grew as a modest fishing and trading port with a mix of Thai, Chinese, and Chao Leh (sea gypsy) influences, reflected in timber houses and seafood cuisine along the shore.
Expect clear snorkel spots over fringing reefs, vibrant reef fish, and occasional turtles or blacktip reef sharks in the shallows. The tour balances breath-taking highlights with practical comforts: lifejackets, masks, lunch on the sand, and hotel transfers from Koh Lanta.
Practical tips — arrive with reef‑safe sunscreen, a lightweight dry bag, and a quick snack if you get peckish before the buffet. Plan for a 7‑hour day, choose morning departures in monsoon season for calmer seas, and follow your guide through Emerald Cave — currents can surprise you. This is a relaxed, accessible marine day that rewards small-group exploration and basic snorkeling skills.
