Thailand is sandwiched between The Gulf of Thailand on its eastern coastline and the vast expanse of the Andaman Sea on its western coast. It is in these body of waters that scuba divers can explore the marine life of the Indian Ocean and the Pacific Ocean without having to cross continents.

Thailand’s Andaman Sea stretches 870km (541 miles) from Tarutao National Park on the border of Malaysia to the Surin Islands on the border of Myanmar (formerly known as Burma). It is part of the Indian Ocean and is separated from the Bay of Bengal by the Andaman-Nicobar Ridge. Quaint formations of granite outcrops can be senn in the Surin and Similan Islands.
