Expedition to the Mergui Archipelago

Unexplored & Undiscovered by Even The Most Seasoned divers!

About Mergui Archipelago

Scattered like pearls on a blue velvet bed sheet are a bunch of 800 islands scattered over the Andaman sea just off the eastern coast of Myanmar. This is Burma’s tropical paradise of Mergui Archipelago. The British colonial name of “Mergui” still remains as opposed to the Burmese “Myeik”.

Myanmar has got turquoise waters, palm-fringed white sand beaches, amazing dive sites, rich wildlife, mangrove forest, but despite the fact that there are only a few islands in Thailand, comparatively, Mergui Archipelago, is far less famous than its Andaman Sea neighbor, the surin and similan islands.

In fact, Myeik Archipelago is one of the world’s best-kept secrets due to the fact that it was only opened to tourism in 1997 and is still under quite a strict regulation.

If you want the most unique Burma diving experience in the planet, then Myanmar (formerly known as Burma) is the place for you. Its waters were closed off until 1997, which means that they are relatively unexplored and undiscovered by even some of the most seasoned divers. With gorgeous landscapes made of caves, soft and hard coral, incredibly rich wildlife and exclusive dive sites, it is diving like you’ve never done it before.

Burma’s Mergui Archipelago offers over 800 islands sprinkled throughout 12,000 square kilometers of crystalline waters just begging to be discovered. Since Burmese waters were opened, only a few boats have begun to appear, yet the islands remain almost entirely uninhabited save for the odd Burmese sea gypsys. Most divers who go to Burma seek the mysterious waters of the Mergui Archipelago. This off-the-beaten-path diving destination is made mostly from limestone (ensuring there are plenty of caves and tunnels) and a few granite pinnacles circled by a wide diversity of corals of beautiful color.

Diving Burma gives you the possibility to run into species like manta rays, barracudas, frogfish, crabs of all types (spider crabs, decorative crab, sponge crab…) seahorses, and all types of shrimps (harlequin being my favorite, I also love marble shrimp and . Different kinds of sharks also populate the area, and often swim along divers. The reefs in the area are also quite impressive, not only because of their sheer beauty, but also because of their size- some reefs can be as large as a small house!
