The Mergui Archipelago (also Myeik Archipelago or Myeik Kyunzu) is an archipelago in far southern Myanmar (Burma) and is part of the Tanintharyi Region.
It consists of more than 800 islands, varying in size from very small to hundreds of square kilometres, all lying in the Andaman Sea off the western shore of the Malay Peninsula near its landward (northern) end where it joins the rest of Indochina.
Occasionally the islands are referred to as the Pashu Islands because the Malay inhabitants are locally called Pashu.
They can be found living on their traditional boats during the dry season, but usually keep to land in the rainy season.
The best diving conditions exist from December to April, with whale sharks and manta rays visiting from February to May. A five-star casino and golf resort, the Andaman Club now operates on Thahtay Kyun Island.
