Myanmar's Mergui Archipelago

One of diving's last great frontiers.

Closed to the outside world until 1997, Myanmar's Mergui Archipelago — over 800 islands scattered across 12,000 km² of the Andaman Sea — remains one of diving's last great frontiers, relatively unexplored and undiscovered.

The islands remain almost entirely uninhabited, except for the Burmese sea gypsies. This off-the-beaten-track destination has been built from limestone, creating a labyrinth of caves and swim-throughs, with a scattering of granite pinnacles ringed by soft and hard corals in beautiful colour.

Diving the Andaman Sea here means the chance to come face to face with whale sharks, manta rays and barracuda, while the macro life delivers frogfish, seahorses, nudibranchs, crabs and shrimp — and blacktip and nurse sharks often cruise alongside divers. With isolated pinnacles, caves and exclusive dive sites all to yourselves, the Mergui Archipelago and the Burma Banks offer some truly breath-taking diving. We can't say you're definitely going to see whale sharks, but they're there.

You'll explore the Mergui Islands aboard the M/Y Thailand Master, a classic timber phinisi under her signature red sails. Seven cabins carry a small group in comfort, with spacious dive decks, an easy-going saloon, and four dives a day on days 2–6, then two dives on day 7 — up to 22 dives across the trip.

Note: We have carefully chosen only twin-share cabins for our guests — no quad share. The trip price reflects this and means you'll be sharing with just one person, not three.
