From the Mergui Archipelago of Myanmar to the Similan Islands of Thailand and the Andaman Islands of India, liveaboard diving in the Andaman Sea is known for whale sharks, manta rays and adventure.
One of the most popular liveaboard diving destinations, the Andaman Sea boasts islands in Thailand, Myanmar and India. Thailand is home to the Similan Islands, Koh Bon and Richelieu Rock. Here, you’ll find some of the best whale shark and manta ray encounters in the world. In Myanmar, most sites are in the Mergui Archipelago, which offers shark encounters to the west. Finally, India is home to the Andaman Islands, only open to tourism since 1993. With pristine reefs and manta rays, these remote islands are worth traveling for. All of these destinations are only accessible by liveaboard, and typical itineraries last 4 to 8 days. The best time to dive in the Andaman Sea is from October to May.
