Mergui Archipelago Liveaboard Diving
The mostly-unexplored 800+ islands of Myanmar's Mergui Archipelago are many divers' dream destination. Although the logistics of getting there are not easy, the location is not remote, less than 500 kilometres from Bangkok. But the challenging logistics have contributed to the untouched & unexplored aura that Mergui has. Connected to The Bay of Bengal, and therefore part of The Indian Ocean, Mergui has diverse and abundant marine life, that comes in all shapes and sizes. Getting there nearly always requires travelling through the south of Thailand, normally to board in or near Ranong.

The Mergui Archipelago is also known as the Myeik Archipelago, in southern Myanmar, also known as Burma. Mergui & Burma are the colonial names, whereas Myeik & Myanmar are the new/official names. For thousands of years, these islands have been home to abundant and diverse marine life, only seen by the indigenous people who live off the sea.
Fans and corals - Credit Johan Folmeus These 'Moken Sea Gypsies' still inhabit some of the islands of Mergui as well as The Surin Islands in Thailand. Then in the middle of the 20th century, the country was cut off from most of the rest of the world. But in recent years the number of dive operators offering liveaboard diving trips into Burma has slowly increased. The most common point of boarding and entry is where the coasts of Myanmar and Thailand meet, at Ranong or Phang Nga, in Thailand. It is then just a very short trip into Myanmar to stamp documents at the local immigration office before sailing off into this vast and wonderful archipelago. New dive sites are still being discovered and explored all the time, and this will continue for years to come. There are dozens of dive sites, which include caves, swim-throughs, currents and vertical walls. The liveaboard diving offers a mixture of ok to fantastic visibility, gentle to strong currents, easy to challenging dive sites, and seahorses & nudibranchs to pelagic sharks & rays. There really is something for everyone, and what makes it better is the lack of other dive boats for as far as the eye can see. The low number of other liveaboards adds to the special feeling of diving in Mergui. And the reason for there not being many boats is mainly due to the bureaucracy & logistics of getting there.
Which areas you can visit for scuba diving in Burma's Mergui Archipelago depends on the length of your trip. Shorter trips tend to stay nearer to the mainland, and longer trips have time to venture further out to sea.
