The Mergui Archipelago, 800 islands of pristine tropical paradise, begins west of Kawthaung in the Andaman Sea and extends some 300km up the coast.
It is what Phi Phi Island and Phuket, down the coast in Thailand, were 100 years ago - crystal clear water, spectacular snorkelling and fiery sunsets in places still undiscovered and unspoilt by mass tourism and resorts.
Only a couple of small resorts have been built on the islands - though there are reportedly plans to develop more in the future - so the only way to explore this semiremote paradise at the moment is by boat. With so few people venturing to the Mergui, and so many islands to choose from, it is easy to feel like you have discovered your own private paradise.
Burma Boating is one of four companies - including Intrepid, Mergui Princess and Island Mergui Safari tours - which are authorised to charter cruises in the archipelago, a national park.
Most of the time, when we enter a bay to snorkel or drop anchor, our beautiful 19th-century-styled boat, with four cloud-coloured sails and an ironwood hull, is the only vessel there.
When we are ferried by a small speedboat to an unpopulated beach, ours are the only toes which touch the crystalline waters and walk its crescents of powdered sand.
