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.
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.

Even after years of diving in Burma, we discover new things and unknown sites on each trip. And the feeling that we are indeed free to continue to explore draws us to this region again and again. Local experience and expertise in this area is rare, so that few operators run live-aboard trips to the Mergui Archipelago. This ensures that dive safaris are both adventurous and relaxing, with practically no other boats to be encountered in the islands and on the dive-sites.
The Mergui Archipelago remains a diving frontier. Individual discovery expeditions of new sites may be arranged by Thailand Dive & Sail. We are currently foremost in exploration of this region.

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.

There are no day-trips to the Mergui Archipelago and it is not a snorkeling destination in and of it's own. However, for non-divers accompanying divers on a live-aboard trip, the islands do provide limites opportunities for snorkeling and swimming. Your live-aboard dive staff will not include a snorkel guide; however, you may make prior arrangements for a private snorkel guide to accompany you on your trip.
Experience the beauty of the Mergui Archipelago on your own sail boat! For individuals, groups and families of sailing enthusiasts, the islands are the ideal tropical destination and perfect basis for extensive diving and island exploration. Moor in stunning bays and enjoy the peace and relaxation of a remote, uninhabited island atmosphere. Adventure on your own time and at your own pace in an environmentally-friendly manner.

back to top"We contacted Thailand Dive and Sail beginning August 2012 for our October holiday. Having booked into a resort we requested daytrip diving plus OWD courses for our two teenagers. Rick had the complicated task of satisfying this request outside normal diving season and he came up trumps. A great French speaking instructor was provided for our kids and we now have an additional two qualified OWD in the family. We did two day's diving from Phuket, one exclusive day's diving on the local Boonsung Wreck and one day's diving in the Similans. Rick and Clive personally did the transfers to Phuket in their fun pickup, all the equipment provided was brand new Aqualung and we had a fantastic four days diving. Don't hesitate to use Thailand Dive and Sail for your daytrip organisation. We will be back to test their live on-board services in the near future. Thanks guys for Diving with a smile ;)"
