Mergui Beach

After hundreds of dives in the Mergui Archipelago off the southwestern coast of Burma, we are still enthralled. The remoteness of the islands, the pristine seascape and the abundant marine life that thrives in this region still holds for us the promise of new discovery. Reachable mainly by live-aboard or sailboat, the isolated islands and dive-sites are never crowded with other boats, perhaps only the occasional Moken sea-gypsy longtail in the distance. A visit to the Mergui Archipelago remains a true sea expedition.

WELCOME TO THE MERGUI ARCHIPELAGO

The Mergui Archipelago (not to be confused with the Burma Banks), comprised of over 800 individual islands, was opened by the Myanmar government to foreign visitors in 1997. Since then, however, it has remained untouched and largely undiscovered. Visitors are free to explore at will, seek potentially new dive-sites and wander uninhabited islands bordered by white sand beaches and dense mangrove swamps. Unlike the Similan and Surin islands to the south, the sea terrain of the Mergui Archipelago is characterized mainly by limestone rock formations. Expansive and intricate dive-sites and excellent visibility ensure adventurous diving. Rare marine species may be sighted, large pelagics are frequent, and colorful hard and soft coral gardens at shallower depths teem with reef fish.

Thailand Dive & Sail is currently the most knowledgeable source of information and experience in the region. We are some of the first people to have explored and mapped the area. Our services include every aspect of a safari to the Mergui Archipelago. Whether it be a live-aboard booking, a reliable guide for your individual trip, a sailboat charter or visits to local Moken settlements, please feel free to contact us – you’re in experienced professional hands.

MERGUI ARCHIPELAGO DIVE SITES

Over the years, our exploration of the region has led us to discover and map many dive-sites scattered throughout the Mergui Archipelago, eleven of which we currently highly recommend for live-aboard trips. The sites are so diverse in their topography and marine life that each time we return, we find something new. The rugged, high-profile dive terrain, and healthy reef ecosystems are home to a myriad of rare indigenous species seen no where else in the world. Encounters with sharks and rays are common. Macro and wide-angle opportunities abound.
