Why go, and how to do it well

Koh Wai is the small island between Koh Chang and Koh Mak, and eight of the Koh Chang island guides I checked include it, more than any island except Koh Mak. There are no roads and no village, just a long wooden pier, a few beaches and simple bungalows.

The guides describe it as the quiet one, small enough to walk, with reefs close to shore for snorkeling straight off the sand. Most people see it as the first stop on an island-hopping day tour from Koh Chang, and a few stay the night once the day boats leave.

Tips for Visiting Islands

Check Island Closures

Similan Islands, Surin Islands, and Koh Tachai close mid-May to mid-October. Some smaller islands reduce ferry service in monsoon season. Always verify schedules before planning your route.

Snorkel Gear Is Cheap to Buy

Rental gear is often scratched and ill-fitting. Buy a decent mask and snorkel at a Big C for 300–500 THB — cheaper than two days of rentals and much more hygienic.

Bring Cash to Smaller Islands

ATMs on smaller islands like Koh Kood, Koh Mak, and Koh Yao charge high fees and sometimes run out of cash. Withdraw enough on the mainland before heading over.
